[Morphofunctional characteristics of the associative region of the cerebral cortex in experimental neuroses in the dog].

Ultrastructure of neurones and synapses of the cortical associative area of dogs has been studied under conditions of experimental neuroses caused by prolonged informational loads with constant time deficit and high motivational signals significance. Analysis of subcellular reorganization of a number of neuronal and synaptic organelles showed the degenerative changes of afferent conducting systems in various neuropil parts leading to the falling out of definite neuronal groups from stable functional connections and to the disturbance of intracortical interrelations. In the cortex simultaneously with destructive processes, are developing intracellular compensatory-adaptive reactions.
