ABSTRACT
The results are outlined of a complex study of the ultrastructure of the rat cerebral cortex after learning and higher nervous activity disturbance. In the case of learning with preliminary stimulation with al-amphetamine or without it, the subcortical processes in the motor and auditory analysers of the cerebral cortex are characterized by sharp structural-functional activation of the apparatus of energy supply, of protein synthesis and of the synaptic zones. The length of the synaptic active zones increases, and extensive development of spine apparatuses is recorded in the postsynaptic area in the form of intricate membrane complexes. Quite the contrary, in cases of higher nervous activity disturbances, destruction of the organelles and desintegration of spine apparatuses is clearly pronounced. The question of the role of the latter in the memory processes is discussed.
