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)

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.
A topic of great interest in the problem of restoration of functions during compensation of cortical trauma [3] is the possibility of plastic restructuring of descending pathways from the undamaged hemisphere [2]. Research conducted by the microstimulation method into the reorganization of cortical motor zones after partial decortication [4, 6] has~ enabled(More)

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)
The ability of donor cerebrospinal fluid from different sources the recover motor functions in partially decorticated rats is estimated. Cerebrospinal fluid from frogs, which have no cortex, and cerebrospinal fluid from donor rats obtained immediately or long after decortication hampers normal recovery of motor function in the recipient rats, while(More)
