Conclusions
-
1.
During the formation of a temporary connection between a nonverbal visual stimulus and an emotionally meaningful word interhemispheric functional relations are significantly altered.
-
2.
The conditioned stimulus evokes local activation chiefly in the visual cortex of the left hemisphere, as a result of which interhemispheric relations in the latent period of the evoked cortical response are reversed.
-
3.
Temporary connection formation is not reflected in the amplitude-time parameters of the evoked response to the conditioned stimulus in the association area.
-
4.
Extinction of the temporary connection and, consequently, restoration of interhemispheric functional relations such as were observed before conditioning, take place slowly, after 100–150 presentations of the stimulus without reinforcement.
