Dataset of spiking and LFP activity invasively recorded in the human amygdala during aversive dynamic stimuli
We present an electrophysiological dataset collected from the amygdalae of nine participants attending a visual dynamic stimulation of emotional aversive content. The participants were patients affected by epilepsy who underwent preoperative invasive monitoring in the mesial temporal lobe. Participants were presented with dynamic visual sequences of fearful faces (aversive condition), interleaved with sequences of neutral landscapes (neutral condition). The dataset contains the simultaneous recording of intracranial EEG (iEEG) and neuronal spike times and waveforms, and localization information for iEEG electrodes. Participant characteristics and trial information are provided. We technically validated this dataset and provide here the spike sorting quality metrics and the spectra of iEEG signals. This dataset allows the investigation of amygdalar response to dynamic aversive stimuli at multiple spatial scales, from the macroscopic EEG to the neuronal firing in the human brain.
The paper reviews contemporary research of group helping behavior - help for some members of outgroup or outgroup as a whole. Various forms of selfish helping (help, contrary to stereotypes, defensive help) and factors of intensity of the helping behavior are analyzed. In conclusion, describes the limitations of existing studies
Key characteristics of non-fluent (Broca, motor) aphasia are, among others, verb finding difficulties and effortful speech output. These characteristics are related to different levels of speech production (lexical retrieval and motor execution). This study was aimed at identifying normative brain activation related to verb production in healthy individuals, as well as patterns of its reorganization depending on the locus of the linguistic deficit in patients with non-fluent aphasia.
The Abstract book contains the abstracts of the posters presentations of the participants of the Methodological school: Methods of data processing in EEg and MEG, Moscow, 16-30th of April, 2013. The School was devoted to the theoretical and practical aspects of the contemporary methods of the dynamic mapping of brain activity by analysis of multichannel MEG and EEG.

Meaningful life is emotionally marked off. That’s the general point that Johansen (IPBS: Integrative Psychological & Behavioral Science 44, 2010) makes which is of great importance. Fictional abstractions use to make the point even more salient. As an example I’ve examined Borges’ famous fiction story. Along with the examples of Johansen it provides an informative case of exploring symbolic mechanisms which bind meaning with emotions. This particular mode of analysis draws forth poetry and literature in general to be treated as a “meaningful life laboratory”. Ways of explanation of emotional effect the art exercises on people, which had been disclosed within this laboratory, however, constitute a significant distinction in terms that I have designated as “referential” and “substantive”. The former appeals to something that has already been charged with emotional power, whereas the latter comes to effect by means of special symbolic mechanisms creating the emotional experience within the situation. Johansen, who tends to explain emotions exerted by the art without leaving the semiotic perspective, is drawn towards the “referential” type of explanation. Based upon discussions in theory of metaphor and Robert Witkin’s sociological theory of arts it is demonstrated an insufficient of “referential” explanation. To overcome a monopoly of “referential” explanation of emotional engagement, in particular, in literature, means to break away from the way of reasoning, stating endless references to “something else”, presupposing the existence of something already significant and therefore sharing its effects.
