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.
The search for specific treatment of disturbed functions after brain injury remains an urgent problem even today. Methods of transplantation of brain tissues and cerebrospinal fluid therapy, which involve the obtaining of material from donors [2, 3], are evidently the most promising approaches. This paper describes an attempt to activate the injured(More)
1. A high degree of stability of the position of the cortical areas of the motor representation of the fore and hind limbs has been shown in intact rats; within those limits individual variability of the zones of the motor representation of individual joints was observed within those limits. 2. Following the partial left-sided decortication of the adult(More)
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)
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)
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)
