title: [The spatial synchronization and power of the alpha and theta rhythm after action of signals Go/NoGo].
abstract: At adult healthy subjects (n = 35) in pause between the target (facial expression) and triggering stimuli showed the conditioning signals of Go/NoGo defining significants of triggering stimulus. The low-frequency alpha rhythm reacts to stimuli Go/NoGo in the left hemisphere more strongly. The coherence of low-frequency alpha potentials on 5-7 second after positive and negative conditioning (Go/NoGo) stimuli increases. Just before the triggering stimulus irrespective of their sign, confirms situation that development of a differentiation demands not less functional activity, than positive conditional reaction. Modulation of cortical activity is connected generally with the talamo-cortical system of selective attention. The coherence a theta rhythm increases after action of positive conditioning signal in the medial cortical areas. It is linked with the function of emotional memory.
