title: [Interaction of amygdalar neurons of active and passive rabbits in negative emotional situations].
abstract: Interaction of basal and central nuclear neurons of amygdala was studied by plotting histograms of crosscorrelation in passive and active rabbits exposed to emotionally significant stimuli. The behavior of animals was studied in the open field, light-dark test and during presentation of emotionally significant stimuli. Rabbits of different typological groups applied a certain behavioral strategy in a variety of behavioral tests. Intergroup differences were revealed in the interaction of neighboring cells of amygdala. Passive rabbits (as comparied to active rabbits) demonstrated more excitatory connections and less inhibitory connections with the latency from 50 to 150 ms. Interactions with the delta1-range and theta2-range frequencies in passive animals were more rarely observed. The asymmetry of the interhemispheric neuronal interaction in amygdala with the right dominance was revealed in passive but not active animals. The results testify that amygdala is involved in the choice of behavioral strategy, and the level of its activation is higher in passive animals.
