title: [Correlation of the rat behavior after immobilization with structural reorganization in the motor cortex].
abstract: Behavioral changes and accompanying morphological neuron-glia reorganization in the rat brain were compared after emotional stress. Wistar rats (n = 20) were stressed by the interrupted immobilization, which was carried out during one week 7-8 h daily. Behavioral immobilization of rats was accompanied by an increase in horizontal and vertical locomotors activity and in duration of the III and IV phases of grooming ("comfortable" grooming) in the "open field" test. The morphometric studies showed a statistically significant increase in the density of hypoxic neurons in the right neocortex of the experimental animals as compared with control. Hypoxic changes in neurons were of functional character. Experimental rats can be considered as a model of redistribution of functional brain activity with preferential intensification of the left brain hemisphere.
