[Structuro-functional organization of thalamic insufficiency].

The role of thalamic parafascicular complex in the intellectual processes was studied in freely behaving cats using an original model of alternative choice with different signal systems generalization based on the principle of preverbal notions formation. Lateral and medial parts of the thalamic parafascicular complex represent two systems of different information processing. These were connected, on the one hand, with the conditioned reflex activity of the brain and on the other, with the generalization function.
