Abstract

On April 18, we were surprised by the news that neuroscientist Dr. Jaak Panksepp had passed away. Dr. Panksepp in his last days was Professor of the Integrative Physiology & Neuroscience at Washington State University and Emeritus Professor of the Department of Psychology at Bowling Green State University. Talking about the importance of his legacy is both simple and unbelievably difficult. But it is just a superficial contradiction. It is simple because his work had an immense and undeniable impact. It is difficult, because it has brought about so many transformations in so many areas that everything that can be mentioned will never be enough. Also, in his work there is plenty of subtleties with great implications. Little is left out of the impact of his work, not only scientifically, but also as part of the Human Weltanschauung from the philosophical point of view.

A few days ago, on April 18, we were surprised by the news that
neuroscienst Dr. Jaak Panksepp had passed away. Dr. Panksepp
in his last days was Professor of the Integrave Physiology &
Neuroscience at Washington State University and Emeritus
Professor of the Department of Psychology at Bowling Green
State University.
Talking about the importance of his legacy is both simple and
unbelievably dicult. But it is just a supercial contradicon.
It is simple because his work had an immense and undeniable
impact. It is dicult, because it has brought about so many
transformaons in so many areas that everything that can be
menoned will never be enough. Also, in his work there is plenty
of subtlees with great implicaons. Lile is le out of the impact
of his work, not only sciencally, but also as part of the Human
Weltanschauung from the philosophical point of view.
A short, but insighul, biography of Panksepp has been compiled
by Robin Stock, so there are no innovaons to be made in this
topic:
“Jaak Panksepp was born on June 5, 1943 in Tartu, Estonia. He and
his family ed to the United States when the Soviets began to take
over his country. Panksepp earned his B.S. in Psychology in 1965
from the University of Pisburgh in Pennsylvania. In 1967, I earned
his M.S. and in 1969 his Ph.D. both in Physiological Psychology at
the University of Massachuses in Amherst, Massachuses. His
graduate thesis focused on electrical smulaon and lesions of
the brain and the corresponding behavioral eects. His thesis,
"The Neural Basis of Aggression in the Albino Rat," focused on
the behavioral consequences of incenve shis, eects of drug
on self-smulaon and aggression, and behavioral analysis
on posive and aversive electrical smulaon of the brain.
Panksepp completed a postdoc in 1971 at the University of
Sussex in Brighton, England, where he studied the role of medial
hypothalamic lesions, insulin, and protein synthesis inhibion in
feeding behavior. At the Worcester Foundaon in Shrewsbury,
Massachuses, I completed another postdoc in 1972 in sleep
physiology.”
So, Dr. Panksepp lived his life as a good and honest man and it
could sustain an interesng and capvang poetry of daily life,
but what is truly amazing is his work.
The general lines of his work emphasized that Emoons seem
to be the most fundamental of the hard-wired neural circuits
in the visceral-limbic brain that facilitate diverse and adapve
behavioral and physiological responses to major classes of
environmental challenges. Presumably these circuits developed
early in the mammalian brain evoluon, and the underlying
control mechanisms remain similar in humans. This would
suggest that theorecally guided studies of the animal brain can
reveal how primive emoons are organized in the human brain.
Let Panksepp himself explain:
“[…] conversely, granted this cross-species heritage, it is arguable
that human introspecve access to emoonal states may
provide direct informaon concerning operaons of emove
circuits and thus be a primary source of hypotheses for animal
brain research. In this arcle the possibility that emoons are
elaborated by transhypothalamic execuve (command) circuits
that concurrently acvate related behavior paerns is assessed.
Current neurobehavioral evidence indicates that there are at
least four execuve circuits of this type–those which elaborate
central states of expectancy, rage, fear, and panic. The manner in
which learning and psychiatric disorders may arise from acvies
of such circuits is also discussed” [1].
The four (at least) execuve circuits quoted above later became
7, as we can see above. The manner in which learning and
psychiatric disorders may arise from acvies of such circuits is
also very extensively discussed across his work. With this in mind,
one can easily understand that if this assumpon is true, animal
brain research will reveal the basis and the general architecture
of emoons in the human brain.

No one can overrate this issue as far as “boom-up” and “top-
down” quesons are concerned. This means that the center
of control of the acon or system acvaon starts in the body
feelings or come from encephalic regions. We can appreciate
this in a special paper called “Integrang boom-up internalist
views of emoonal feelings with top-down externalist views:
Might brain aecve changes constute reward and punishment
eects within animal brains?” [5].
Again, the implicaons are immense. It is enough to see the
tle of one of his last books: ‘’Social Behavior from Rodents
to Humans’’ [6], where one of the chapters is justly called
‘’The Psycho-Neurology of Cross-Species Aecve/Social
Neuroscience: Understanding Animal Aecve States as a Guide
to Development of Novel Psychiatric Treatments”.
In an aempt to situate its impact of Panksepp on a short
comment, a synthesis was necessary, which implies some
simplicaon, but, even at this risk, we can understand the
importance of his scienc work, both from the point of view
of research, as well as the philosophical point of view, and the
resulng interacon between the two.
The human and biological sciences, in their eorts to understand
the human being or even to dene it, always lead to the queson
of emoons. Panksepp with his aecve neuroscience model
could situate the role of the basic emoons in the behavior,
bringing these quesons to the methods of the natural sciences
and allowing it to be studied at the laboratory. This eort
brought other consequences, enabling the consolidaon of
the knowledge of the human being as "a being" of nature. By
a strange aberraon of these methodological dicules quite
oen le aside, the Human being stood apart from nature, as in
a solitary solipsism.
Panksepp "animated" us (give us a “anima” a “natural soul”, his
results and methodological approach allowed the human being
to be animal, in a absolutely good and new way to consider these
quesons); in a profoundly existenal sense, he had returned us
to Nature. The opposite also applies: his work had “humanized”
the “other animals”, and both us “animals” and “human” became
closer and very near, indeed.
Starng from the work of pioneer giants such as Konrad
Lorenz, Nicholas Tinbergen, among others (and therefore the
development of an epistemology based on an evoluonary
understanding), this knowledge made possible the emergence
and development of neuroscience and a scienc analysis of
emoonal behavior, bringing the human being more consistently
close to the Animal Kingdom; it also began to be analyzed in an
extremely procient way under the paradigms of causality and
from an empirical point of view.
With his researches and discoveries on the neural systems
generang of emoons, he has shed immense light on this
eld, which allowed for an approach that aligned the behavior
of several species and their funcon, and brought together
several elds of research and several other areas of knowledge,
such as Psychology, Biology, Anthropology, Psychoanalysis, and
several works like those of John Bowlby. Let us see, for example,
Based on this, Panksepp described seven primary processes.
Each one of them is in charge of a parcular kind of possible
environmental challenges and his repertoire of adapve
behavior. Each one of these seven sets is genecally provided
with emoonal systems of mammalian brains. Also, the author
stressed that all these systems are subcorcally localized, so it is
not possible to invesgate with modern brain imagery.
This seven basic emoons or emoon systems consist of the
seven “neuronal process” [2]:
1. SEEKING/Enthusiasm;
2. RAGE/Anger;
3. FEAR/Anxiety;
4. sexual LUST/Passion;
5. maternal CARE/Nurturance;
6. PANIC separaon/distress, Grief; and
7. PLAY/Social Joy.
How the author himself stressed several mes across his work,
most of these systems gure heavily in social bonding, and social
bonds are very important to mammals. We can add to this that
there is very strong evidence linking the high encephalizaon and
complexity of social life in primates, like us, humans [3].
Based on these seven systems Panksepp presented a
methodology for the study and comprehension of several kinds
of pathologies. In Current Topics in Behavioral Neuroscience [2],
for instance, he and his team describe depression as a “sustained
overacvity of the separaon-distress PANIC system reecng
severed social bonds and the excessive "psychological pain" of
loneliness that, if sustained, can lead to a downward cascade
known as psychological despair, and (ii) The despair phase that
follows the PANIC response, which is characterized by abnormally
low acvity of the SEEKING, the so-called brain reward networks,
leading to a movaonal states that characterize depression. To
understand why depression feels so bad, we must understand
the neural mechanisms that mediate such social feelings.”
From this, always relang the funcon of the systems of primary
emoons, both in the evoluonary sense, as an anatomical and
biomolecular point of view, we have the solid foundaon for a
branching of studies in several areas. This can be viewed in tles
of some of his most recent works, such as "Posive Emoonal
Learning Induces Resilience to Depression: A Role for NMDA
Receptor-mediated Synapc Plascity" [2], where we can see the
remarkable approach of complex behaviors, personal experiences
and changes at a cellular-molecular level. Here we can see
the remarkable advance that his concepons and results have
brought to the understanding of what Tinbergen called "proximal
causes" [4]. Considering emoons as primary tools shared by
all mammals, we have that they play their part in a boom-up
pathway, favoring a class of behaviors that have proven most
suitable in the evoluonary past of this genre. This has major
implicaons in the frame where research and concepons and
theorecal approach give shape to the “making hypothesis”
process, even in quesons about the mind-body theme.

this statement by Panksepp, "the aachment system begins in
the midbrain periaqueductal gray, very close to the area that
produces physical pain responses, suggesng that it may have
originated from the pain circuits ", from this observaon we
can beer understand how certain types of environment can be
harmful to health.
We can state that Panksepp's book, “Aecve Neuroscience:
The Foundaons of Human and Animal Emoons”, Oxford
University Press [7], will be one of the most important
contribuons to the understanding of the biology of emoons
since Darwin’s “The Expression of the Emoons in Man and
Animals”. We should also quote other books of his own, “The
Archeology of Mind: Neuroevoluonary Origins of Human
Emoon” [5]; “The Textbook of Biological Psychiatry”, (2004);
“Emoons and Psychopathology”, (1988); “Handbook of the
Hypothalamus: Behavioral Studies, Physiology and Anatomy of
the Hypothalamus” (in 4 volumes) and many others. It helped us
to understand emoons as a tangible part of our existence and
not as a mere abstracon, almost unreal, as tended to consider
the science of the century XIX unl almost the end of the XX.
The fact that emoon would have adapve value was already
in Darwin's texts (1872): The Expression of the Emoons in Man
and Animals). But with Panksepp's work, it reached a degree of
clarity and a high level of comprehensiveness that made possible
the explanaon and punctual understanding of each class of
behavior, going to its anatomo-funconal and neurochemical
descripon. As we can see in this passage of Vuilleumier:
"emoonal processes not only serve to record the value of
sensory events, but also to elicit adapve responses and modify
percepon" [8].
In short, aer his work some changes were made possible:
1. Denitely consider emoon as a eld of scienc research,
independent of the logical-philosophical dicules to
handle the subject;
2. To bring the emoonal life of the human being closer
to that of other species, making it possible for a whole
eld of research on a more substanal basis to be able
to theorecally relate the results of comparave research
with other animals and with humans;
3. To understand the human being integrated into and within
Nature, leaving the “obscured area” in which this animal
was segregated with dierence and dierenated from
the whole biological kingdom;
4. It made possible the systemac study of the dierent
classes of behaviors linked to their purpose, in relaon
to both the proximal and nal causes, in the concept of
Tinbergen, opening a wide eld of research, both basic
and clinical;
5. Finally, Panksepp, teaches us that our emoons and our
es, what moves us and drives us, our goals, are not
superior or so dierent from those of other animals ...
we are as fragile and sweet as lile lab rats, laughing and
joking, while trying to make bonds, escape pain, seek
pleasure ... While opening the eld and paving the way
for understanding complex behaviors, by situang the
problem of emoon for understanding the brain, it builds
a solid foundaon for the researches on conscience.
According to a very quick research on Google Scholar, we could
see this remarkable result: Panksepp published 648 works,
including books and periodicals, and obtained 43,337 citaons,
which proves that he has been the great and generous writer
when sharing such wide knowledge.
Only one thing comforts us in this loss: the innite beauty of an
existence that is complete, leaving behind the very meaning of
‘yes, it was worth coming!’
With gratude, we say farewell to this great scienst!

Oxytocinergic System: a proposal João Paulo Correia Lima* and Avelino Luiz Rodrigues Department of Clinical Psychology and Nucleus of Neuroscience and Behavior, Institute of Psychology, University of Sao Paulo, Brazil *Corresponding Author: João Paulo Correia Lima Psychologist for Neuroscience and Behavior Institute of Psychology University of Sao Paulo, Brazil Tel: +55-11-32852420, +55-11-983439754 E-mail: joaopclima@usp.br Introduction Since 1910, when Ott and Scott (1910) published their discovers about the oxytocin participation in milk ejection, the comprehension about function and role of oxytocin in several physiological functions didn’t stop didn't stop enlarging and growing. In birth, through his action over uterus contractions, in uterus contractions in women’s orgasm (Master and Johnson, 1966) and men’s erection (Andersson, 2011; Carter,1992), for instance. However, this approach always considers its peripheral effects. After this, some oxytocin effects had been reported to have actions over behavioural traits, like we can see in publishings of Pedersen and Prange (1979) and Winslow and co-workers (1993), reporting the oxytocin actions over, respectively, maternal behaviour and pair bonding. Since then, the increasing data about the oxytocin’s function in behaviour and its central action can’t be ignored. In this short proposal, we’ll consider the opportunity or utility of thinking about oxytocin as a system, instead of a single neurotransmitter. Neurotransmitter or Hormone: central and peripheral actions of oxytocin Once a molecule could have his function defined through the way it acts over the organism, not for his special chemical properties we can think about oxytocin as a hormone or neurotransmitter. If it is released into the bloodstream and have his effects on distant organs, we used to consider a particular molecule a “hormone”. If this release takes place in a close and specific locus, very close to the releasing point and with specific effects, we used to consider this molecule a “neurotransmitter”. So, oxytocin has both functions and its neurotransmitter action has been heavily and abundantly reported in academic publishing since decades ago to more recent studies (Swanson, Hökfelt, & Björklund, 1987; Sofroniew, 1980; Onaka, 2014; Herbert, 1994; Sawchenko & Swanson, 1982). More recently we found the oxytocin participation in broader traits, as social behaviour (Donaldson & Young, 2008; Goodson & Thompson, 2010; Heinrichs, Dawans & Domes, 2009) in a great spectrum of functions and actions, like affiliative and romantic behaviours (De’Biec, 2007), empathy (Wu, Li & Su, 2012; Ahmad, Palgi, Klein, Decety & Shamay-Tsoory, 2015) or the oxytocin’s effect in social contact (Üvnas-Moberg & Petersoon; 2005; Üvnas-Moberg, 1997) and the benefits of oxytocin-releasing over stress (Uvnäs-Moberg; 1999; Onaka, Takayanagi & Yoshida, 2012). This kind of publishing list goes far and far (Olff et all, 2013). Special mention to the Porge’s work (2011), who assembled great amount of data about a social behaviour system, including a particular theory that gathers these results in a comprehensive whole, presenting the idea that the mammalians have three system: social engagement system (relax and interact, oxytocin being the main neurotransmitter), mobilization system (to face the challenges, stress-like reactions) and immobilization (feigning death, passive avoidance). In the same direction, we have the Cozzolino works (2014), who consider the human relationships in a neural point of view, presenting the importance of oxytocin in attachment too. There is a great number of publishing about the importance of oxytocin in social behaviour or even and especially the importance of this molecule to regulate stress reactions in a very beneficial way, in this way our research about oxytocin effects on stress reaction in a model of social stress: the findings were indicative that oxytocin exerts a inhibitory effect on cortisol levels, pointing oxytocin have a inhibitory effect over stress reaction (Lima, 2017). In a very informative and insightful publishing, Lee and co-workers (2009) reviewed the actions of oxytocin and noticed that all these actions can be understood under a single line: interaction, social behaviour, friendship, bonding, reproduction and nurture. In this line of thinking they consider oxytocin “the great facilitator of life” (indeed, the title of his article). Reasons for an Oxytocinergic System Research Some consider this kind of proposal simply “philosophical”, or, in other words, purely logical questions with no empirical consequences. We consider it in a very different way. When you think about dopamine like a “rewarding system” we can understand a lot of behaviours better, like addiction or the search for something “better” in human behaviour. Or when we consider the clinical approach of serotonin, we think better when we consider how it can be relevant to the human mood with great consequences for the affective disorders treatment. This progress does not come considering simply or uniquely a molecule effect, isolated from a class or behaviour that we have studying at the moment. When we think of emotions in the context of mammalian survival we can understand its action much better and in an insightful way, like in Panksepp analysis (Panksepp, 1998; Lima & Rodrigues, 2017). Bringing to the discussion Nicholas Tinbergen's teachings (1963), the researchers must always have in mind the different classes of causes. Considering the action of a single molecule the researcher is in the field of “proximate explanations”. And when the researcher considers a “system”, involving a certain class of behaviour, he is able to step forward to “ultimate explanations”, what brings the full picture. So, it is not a simple matter of “philosophical” question, but the very ground of Evolutive Psychology. Not considering this can bring a lot of unfortunate misleading and misinterpretation of the results. It is so because we are trying to understand an organism, not a single chemical interaction isolated from the context where it happens – the animal itself (despite the fact that without understanding the chemical interaction we can’t understand the whole). Simplifying the complex to achieve a better comprehension of the whole is an approach that has brought to us much of our actual knowledge (Kandel, 2016). So, when we have solid material and information about a molecule and its action through a range of functions and behaviours, and we can see that these actions belong to the same class, is time to consider if we don’t have a “system”. Which advantage does it bring to us? The same that we have found in considering a “noradrenergic system” or a “dopaminergic system”. A concept like “oxytocinergic system” makes question formulation easier formulating questions, design experimental essays and the interpretation of the results can be much more accurate. Conclusions The research about complex behaviour has had a great benefit and improvement when we consider not just a punctual effect of a molecule, but its action in a broader context. Why not think about oxytocin as a system with a particular function and purposes instead of a simple molecule? It is time to change it and subscribe “oxytocin” officially a system of social behaviour with great function against the hazardous chronic stress effects. We say “officially” because it already happens informally. Despite in scientific publishing, one doesn’t find the expression “oxytocinergic system” we think about oxytocin as a system of social behaviour. It seems to us that is a great advance and means a guidance for the future research and discussion of the results of essays and can put the question that drives the research in a more accurate way. Adding to it, this allows the approximation of social issues and psychological questions to the laboratory, what we can see – very richly in stress studies, for instance. We also consider it could be a great progress for the teaching and training of students in the field, presenting the subject in a more organized way allowing a deeper understanding of the architecture of behaviour, linking it with the purposes of life and the general lines of the biological way of thinking. After all, the understanding of the particular effect of a molecule only gets this true meaning when we consider the broader effect in a singular class of behaviour that have this purpose in the pursuit of living well. And in its lays the ultimate porpoise of the scientific labour: the understanding and improvement of the well-being with significance.

Group size covaries with relative neocortical volume in nonhuman primates. This regression equation predicts a group size for modern humans very similar to that for hunter-gatherer and traditional horticulturalist societies. Similar group sizes are found in other contemporary and historical societies. Nonhuman primates maintain group cohesion through social grooming; among the Old World monkeys and apes, social grooming time is linearly related to group size. Maintaining stability of human-sized groups by grooming alone would make intolerable time demands. It is therefore suggested (1) that the evolution of large groups in the human lineage depended on developing a more efficient method for time-sharing the processes of social bonding and (2) that language uniquely fulfills this requirement. Data on the size of conversational and other small interacting groups of humans accord with the predicted relative efficiency of conversation compared to grooming as a bonding process. In human conversations about 60% of time is spent gossiping about relationships and personal experiences. Language may accordingly have evolved to allow individuals to learn about the behavioural characteristics of other group members more rapidly than was feasible by direct observation alone.

Some investigators have argued that emotions, especially animal emotions, are illusory concepts outside the realm of scientific inquiry. With advances in neurobiology and neuroscience, however, researchers are proving this position wrong while moving closer to understanding the biology and psychology of emotion. In Affective Neuroscience, Jaak Panksepp argues that emotional systems in humans, as well as other animals, are necessarily combinations of innate and learned tendencies; there are no routine and credible ways to really separate the influences of nature and nurture in the control of behavior. The book shows how to move toward a new understanding by taking a psychobiological approach to the subject, examining how the neurobiology and neurochemistry of the mammalian brain shape the psychological experience of emotion. It includes chapters on sleep and arousal, pleasure and pain systems, the sources of rage and anger, and the neural control of sexuality. The book will appeal to researchers and professors in the field of emotion.

Emotions seem to arise ultimately from hard-wired neural circuits in the visceral-limbic brain that facilitate diverse and adaptive behavioral and physiological responses to major classes of environmental challenges. Presumably these circuits developed early in mammalian brain evolution, and the underlying control mechanisms remain similar in humans and “lower” mammals. This would suggest that theoretically guided studies of the animal brain can reveal how primitive emotions are organized in the human brain. Conversely, granted this cross-species heritage, it is arguable that human introspective access to emotional states may provide direct information concerning operations of emotive circuits and thus be a primary source of hypotheses for animal brain research. In this article the possibility that emotions are elaborated by transhypothalamic executive (command) circuits that concurrently activate related behavior patterns is assessed. Current neurobehavioral evidence indicates that there are at least four executive circuits of this type – those which elaborate central states of expectancy, rage, fear, and panic. The manner in which learning and psychiatric disorders may arise from activities of such circuits is also discussed.
