Topical organization of the motor cortex was compared in outbred rats by the method of intracortical microstimulation in the norm and in different periods after unilateral partial decortication of the motor projection (MP) of the hind-leg. Stable state of the MPs of the fore- and hind-limbs was in the norm, and within their bounds there was an individual(More)

Spatial quantitative aspects of walking are described prior to and after partial extirpation of left motor cortex in rats. Symmetry of the gait returned to normalcy within over three months after the operation. Length and width of the steps did not return to the prior-to-operation level within 12 months.
Some changes of the organization of cortical motor representations, which were revealed by means of the intracortical microstimulation (ICMS) in aged rats after unilateral partial decortication, were true consequences of the decortication, but had no significant relationship to the aging. Distributions of latent periods of contralateral hind-leg(More)
Bilateral mapping of the frontal cortex of rat has been performed. The internal topographic organization of motor zones of the vibrissae was revealed with the low-threshold microstimulation. The comparison of the right and left hemispheres demonstrated some asymmetry in the vibrissae motor representation, its territory in the right hemisphere being larger(More)
The motor function recovery was studied for 3 weeks after surgical unilateral damage of the motor cortex in albino rats. Distance between the 1st and the 5th fingers was compared in intact sham--operated, operated rats, and operated animals which were suboccipitally injected with brain extract obtained from reconvalescent donor rats with the same type of(More)
