- Аннотация: Execution of a conditioned avoidance reflex in rats was associated with the disappearance of the δ rhythm (1–4 Hz) typical of the intersignal period and synchronized between the medial prefrontal cortex and the ventral tegmental area of the midbrain (VTA), and with an increase in the frequency of the synchronized θ rhythm in the same structures and the hippocampus from 6–8 to 8–11 Hz. In terms of the “Granger causality” criterion, the δ rhythm of the prefrontal cortex and the θ rhythm of the hippocampus had predictive value in relation to these rhythms, propagating in the direction of the VTA. Failed avoidance reactions (errors, activation of the conditioned signal in the safe sector of the chamber, acquisition of a classical unavoidable conditioned reflex) led to generation of the δ rhythm in response to the conditioned signal rather than during the prestimulus period, along with disappearance of the θ synchronization between the VTA and the prefrontal cortex. The amplitude and synchronization of the fast (70–160 Hz) γ activity in the VTA with γ activity in the cortex and hippocampus and the discharge frequency of VTA neurons were modulated in relation to the phases of the δ and θ rhythms.
