Neck myoclonus was systematically described and quantitative assessed during REM sleep in a sample of 190 patients (Frauscher et al, 2010). NNM was present in more than 50% of patients (Index 1.0+/-2.7/h). In suspected REM parasomnia of young 26 year-old female this index was reported reaching to 89,9/h (Otto et al 2012).
The stimulus responsivenes...
Introduction
The prognosis of reconstructive surgery for brachial plexus injuries is related to the localisation of injury, whether the damage exists primarily in the brachial plexus, the spinal nerves distal to the dorsal root ganglia, or at the point of connection with the spinal cord (Jones, 1980). The use of somatosensory evoked potentials (SSE...
We present preliminary results from the ongoing study entitled “Icelandic AVH-TMS” which aim is to study the effectiveness of repetitive transcranial magnetic stimulation (rTMS) treatment for patients with schizophrenia and with persistent auditory verbal hallucinations (AVH) using symptoms and psychometric scales and high-density EEG system (256 c...
Schizophrenia is a complex disorder about which much is still unknown. Potential treatments, such as transcranial magnetic stimulation (TMS), have not been exploited, in part because of the variability in behavioral response. This can be overcome with the use of response biomarkers. It has been however shown that repetitive transcranial magnetic st...
With this communication during the first World Jackal Day on 19th April 2023 (https://www.goldschakal.at/gb/world-jackal-day/) we presented the preliminary results of our informal research project on the golden jackal behavioural ecology and reproductive biology in north-eastern Italy.
In the last decade, there has been a remarkable increase in the number of scientific publications on the ecology of the golden jackal Canis aureus , whereas information on its reproductive biology is still scanty, and the basic reproductive parameters of the species are not yet fully understood. In 2021, we began a research project in North-Eastern...

For this purpose, we instructed six patients (SCZ) and six healthy controls (HC) to do an auditory-motor task (AMT) by p...
Hunting is forbidden in Danube Delta Biosphere Reserve since 2010. In 2018, Romanian authorities have reported more than 500 separate outbreaks of African swine fever in pigs, mainly in the Danube Delta and near the Hungarian border. For the 2018-2019 hunting season, 2000 golden jackals were supposed to be removed from the Danube Delta as a harvest...
TMS cortical silent period and electrical cutaneous silent period changes after alcohol acute ingestion. GABA-B intracortical neurons produce an inhibitory effect on abductor pollicis brevis silent period which is enhanced after alcohol ingestion. Cutaneous silent period is known to be modulated only at spinal level by A-delta afferents and alpha m...
The use of transcranial magnetic stimulation (TMS) in schizophrenia has its greatest efficacy in treating auditory hallucinations especially by decreasing the frequency and severity of auditory hallucinations mainly by targeting low frequency TMS stimuli to Wernicke's area in the left temporo-parietal cortex (Cole et al. 2015). Neural circuitry and...
Resting state EEG beta and gamma bands activity is often used to assess changes on physiological processes of the brain with different interventions like medication or noninvasive brain stimulation. Even so, the relative power and the local cortical plasticity changes might be insufficiently analyzed with conventional 18-21 channel system EEG. We a...

Golden jackals show an increasing long-distance dispersal from their known historic geographic range into new areas (Rutkowski et al. 2015). Only in the last years, single golden jackal individuals were reported in Latvia, Lithuania, Poland, Germany or Denmark and a survival cluster of 5 territorial groups (Männil 2016, pers. comm.) is monitored in...
In the first continent-wide study of the golden jackal (Canis aureus), we characterised its population genetic structure and attempted to identify the origin of European populations. This provided a unique insight into genetic characteristics of a native carnivore population with rapid large-scale expansion. We analysed 15 microsatellite markers an...
First European jackal discovered in Denmark, the news came on 13th of September. A male jackal was road-killed near Karup, Central Jutlandia, Denmark during the last summer and was genetically analized. It seems that this jackal arrived to Denmark on the same "Nature Highway" like the other canid, the wolf, few years ago.
I am suggesting an alterna...
Golden Jackal Informal Study Group in Europe (GOJAGE) and Jackal Ecology Task Force (JETF) in Central and SE Europe do not consider the golden jackal to be an invasive alien species in Poland, Lithuania, Latvia, Estonia, Belarus and NE Ukraine.
Golden jackal (Canis aureus) is a widespread canid species ranging from central, eastern and southern Europe
to northern Africa, Middle East and Southeastern Asia. Since the beginning of the 20th century the species’

Nurick and Rawanat classifications for myelopathy are often used for lumbar stenosis symptoms. Is there a name for the compressive lesions in the lumbar spine region? Or we should name this "stenosis"?
In the attached picture Z-score from 0-60 is representing the PSD of low gamma 30-49 Hz, recording with 256 electrodes.. What is the topographical representation? PSD amplitude over sensors how it is translated in a confluent map. Is it that way?
Two weeks since cardiac arrest with 30 min CPR and ECMO. Unresponsive with clinical coma. Blinking spontaneously. Do you see the missing AP gradient. What would be your assessment from now.
Hi, everybody
1) On the issue of QEEG bands frequency absolute or relative power calculations, I wonder if we can us a simple method to assess baseline and post-treatment changes. By example dividing the GBA_fin (Gamma Band Activity after the task or treatment) to GBA_bas (Gamma Band Activity in baseline condition) and name this like Index of Plasticity as described here.
2) The other complementary and mandatory question is: If I am using a High density approach with 256 Channel, how are you seeing the calculation by averaging the result of relative power of 17 electrodes from a region of interest or other divided by the averaged number of 256 channels get one number, then do the same with data after intervention and calculate the RATIO naming this the Index of local Plasticity? Would you accept it?
For the brain, a brief sequence of correlated activity, of the order of milliseconds, may correspond to a highly significant event if it occurs in a large numbers of cells. Such brief synchronous events may pass undetected if they are recorded from limited cells or areas of the brain. The techniques currently available permit to record large cortical surface with high sampling rate from different locations.
The relationships between synchronized neuronal activity and behavior are likely to be detectable only for conditions that maintain synchronization for longer periods of time. Synchronization affects discharge rates by enabling more effective summation than asynchronous inputs. Modulation of response amplitude and synchronization of discharges can operate as complementary mechanisms for the selection and binding of responses.
The auditory-motor task proposed to assess the EEG cortical fragmentation and its clustered topography before and after rTMS treatment for "hallucinated" voices might trigger and modulate gamma activity.
The selection of high spatial and temporal resolution method like 256 channel HD-EEG enhance the effect of this activity and will show the function of the cortico-cortical connections by adjusting the timing of discharges rather than modulating discharge rates.
From our preliminary data we observe that same composed surface of a determined task-time-locked frequency analyzed from power spectral density analyses are constant even if the cluster numbers and area fluctuate considerably after the 10 days rTMS.
How to quantify the EEG fragmentation of these beta or gamma clusters and to use the parameter as a metric of treatment effectiveness?
