[An electrophysiological analysis of the processes in the evaluation of successfulness in the choice of behavioral programs].
The magnitude of the N1 and P3 waves of event-related potentials (ERPs) recorded in the dog medial frontal cortex were shown to depend on the behavioural context of separate trials. The most prominent P3 waves occurred in two behavioural situations: 1) when an unexpected non-reward followed previously rewarded conditioned responses, and 2) when an absence of the reward resulted in behavioural type shift in the next trial. The enhancement of the P3 seems to be due to a common factor: the discordance between the CR or its results and the previously developed behavioural trend.
