A few days ago, on April 18, we were surprised by the news that
neuroscienst Dr. Jaak Panksepp had passed away. Dr. Panksepp
in his last days was Professor of the Integrave 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 dicult. But it is just a supercial contradicon.
It is simple because his work had an immense and undeniable
impact. It is dicult, because it has brought about so many
transformaons in so many areas that everything that can be
menoned will never be enough. Also, in his work there is plenty
of subtlees with great implicaons. Lile is le out of the impact
of his work, not only sciencally, but also as part of the Human
Weltanschauung from the philosophical point of view.
A short, but insighul, biography of Panksepp has been compiled
by Robin Stock, so there are no innovaons 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 Pisburgh in Pennsylvania. In 1967, I earned
his M.S. and in 1969 his Ph.D. both in Physiological Psychology at
the University of Massachuses in Amherst, Massachuses. His
graduate thesis focused on electrical smulaon and lesions of
the brain and the corresponding behavioral eects. His thesis,
"The Neural Basis of Aggression in the Albino Rat," focused on
the behavioral consequences of incenve shis, eects of drug
on self-smulaon and aggression, and behavioral analysis
on posive and aversive electrical smulaon 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 inhibion in
feeding behavior. At the Worcester Foundaon in Shrewsbury,
Massachuses, 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 interesng and capvang poetry of daily life,
but what is truly amazing is his work.
The general lines of his work emphasized that Emoons seem
to be the most fundamental of the hard-wired neural circuits
in the visceral-limbic brain that facilitate diverse and adapve
behavioral and physiological responses to major classes of
environmental challenges. Presumably these circuits developed
early in the mammalian brain evoluon, and the underlying
control mechanisms remain similar in humans. This would
suggest that theorecally guided studies of the animal brain can
reveal how primive emoons are organized in the human brain.
Let Panksepp himself explain:
“[…] conversely, granted this cross-species heritage, it is arguable
that human introspecve access to emoonal states may
provide direct informaon concerning operaons of emove
circuits and thus be a primary source of hypotheses for animal
brain research. In this arcle the possibility that emoons are
elaborated by transhypothalamic execuve (command) circuits
that concurrently acvate related behavior paerns is assessed.
Current neurobehavioral evidence indicates that there are at
least four execuve 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 acvies
of such circuits is also discussed” [1].
The four (at least) execuve circuits quoted above later became
7, as we can see above. The manner in which learning and
psychiatric disorders may arise from acvies of such circuits is
also very extensively discussed across his work. With this in mind,
one can easily understand that if this assumpon is true, animal
brain research will reveal the basis and the general architecture
of emoons in the human brain.

No one can overrate this issue as far as “boom-up” and “top-
down” quesons are concerned. This means that the center
of control of the acon or system acvaon starts in the body
feelings or come from encephalic regions. We can appreciate
this in a special paper called “Integrang boom-up internalist
views of emoonal feelings with top-down externalist views:
Might brain aecve changes constute reward and punishment
eects within animal brains?” [5].
Again, the implicaons 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 Aecve/Social
Neuroscience: Understanding Animal Aecve States as a Guide
to Development of Novel Psychiatric Treatments”.
In an aempt to situate its impact of Panksepp on a short
comment, a synthesis was necessary, which implies some
simplicaon, but, even at this risk, we can understand the
importance of his scienc work, both from the point of view
of research, as well as the philosophical point of view, and the
resulng interacon between the two.
The human and biological sciences, in their eorts to understand
the human being or even to dene it, always lead to the queson
of emoons. Panksepp with his aecve neuroscience model
could situate the role of the basic emoons in the behavior,
bringing these quesons to the methods of the natural sciences
and allowing it to be studied at the laboratory. This eort
brought other consequences, enabling the consolidaon of
the knowledge of the human being as "a being" of nature. By
a strange aberraon of these methodological dicules quite
oen 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
quesons); in a profoundly existenal 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.
Starng from the work of pioneer giants such as Konrad
Lorenz, Nicholas Tinbergen, among others (and therefore the
development of an epistemology based on an evoluonary
understanding), this knowledge made possible the emergence
and development of neuroscience and a scienc analysis of
emoonal behavior, bringing the human being more consistently
close to the Animal Kingdom; it also began to be analyzed in an
extremely procient way under the paradigms of causality and
from an empirical point of view.
With his researches and discoveries on the neural systems
generang of emoons, he has shed immense light on this
eld, which allowed for an approach that aligned the behavior
of several species and their funcon, 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 parcular kind of possible
environmental challenges and his repertoire of adapve
behavior. Each one of these seven sets is genecally provided
with emoonal systems of mammalian brains. Also, the author
stressed that all these systems are subcorcally localized, so it is
not possible to invesgate with modern brain imagery.
This seven basic emoons or emoon 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 separaon/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 encephalizaon 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
overacvity of the separaon-distress PANIC system reecng
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 acvity of the SEEKING, the so-called brain reward networks,
leading to a movaonal 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 relang the funcon of the systems of primary
emoons, both in the evoluonary sense, as an anatomical and
biomolecular point of view, we have the solid foundaon for a
branching of studies in several areas. This can be viewed in tles
of some of his most recent works, such as "Posive Emoonal
Learning Induces Resilience to Depression: A Role for NMDA
Receptor-mediated Synapc Plascity" [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 concepons and results have
brought to the understanding of what Tinbergen called "proximal
causes" [4]. Considering emoons as primary tools shared by
all mammals, we have that they play their part in a boom-up
pathway, favoring a class of behaviors that have proven most
suitable in the evoluonary past of this genre. This has major
implicaons in the frame where research and concepons and
theorecal approach give shape to the “making hypothesis”
process, even in quesons about the mind-body theme.

this statement by Panksepp, "the aachment system begins in
the midbrain periaqueductal gray, very close to the area that
produces physical pain responses, suggesng that it may have
originated from the pain circuits ", from this observaon we
can beer understand how certain types of environment can be
harmful to health.
We can state that Panksepp's book, “Aecve Neuroscience:
The Foundaons of Human and Animal Emoons”, Oxford
University Press [7], will be one of the most important
contribuons to the understanding of the biology of emoons
since Darwin’s “The Expression of the Emoons in Man and
Animals”. We should also quote other books of his own, “The
Archeology of Mind: Neuroevoluonary Origins of Human
Emoon” [5]; “The Textbook of Biological Psychiatry”, (2004);
“Emoons 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 emoons as a tangible part of our existence and
not as a mere abstracon, almost unreal, as tended to consider
the science of the century XIX unl almost the end of the XX.
The fact that emoon would have adapve value was already
in Darwin's texts (1872): The Expression of the Emoons 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 explanaon and punctual understanding of each class of
behavior, going to its anatomo-funconal and neurochemical
descripon. As we can see in this passage of Vuilleumier:
"emoonal processes not only serve to record the value of
sensory events, but also to elicit adapve responses and modify
percepon" [8].
In short, aer his work some changes were made possible:
1. Denitely consider emoon as a eld of scienc research,
independent of the logical-philosophical dicules to
handle the subject;
2. To bring the emoonal life of the human being closer
to that of other species, making it possible for a whole
eld of research on a more substanal basis to be able
to theorecally relate the results of comparave 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 dierence and dierenated from
the whole biological kingdom;
4. It made possible the systemac study of the dierent
classes of behaviors linked to their purpose, in relaon
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 emoons and our
es, what moves us and drives us, our goals, are not
superior or so dierent from those of other animals ...
we are as fragile and sweet as lile 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 situang the
problem of emoon for understanding the brain, it builds
a solid foundaon 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 citaons,
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 innite beauty of an
existence that is complete, leaving behind the very meaning of
‘yes, it was worth coming!’
With gratude, we say farewell to this great scienst!
