To study how additional learning may change the brain activity during realization of initially learnt behavior, we compared EEG potentials in rats performing an instrumental lever-pressing task before and after additional training in a slightly different environment. EEG was recorded over motor, retrosplenial posterior, and visual areas of the cortex. A similar configuration of behavior-related EEG potentials was observed during performing the instrumental task before and after additional learning, which suggests that, in general, common brain processes underlie the behavior in the compared conditions. However, differences in the amplitudes and latencies of components of behavior-related potentials shown in this work support the hypothesis that the composition of the elements of individual experience underlying this behavior changes after additional learning.
