Conclusions
-
1.
Instrumental food-getting movements in cats after blocking of the main part of the afferent inflow to the sensomotor areas of the cortex by division of the posterior white columns and spinocervical tract are considerably disturbed.
-
2.
Restoration of conditioned-reflex responses connected with inborn forms of motor activity (walking, jumping into the chamber, and so on) takes place parallel with recovery of postural and locomotor functions, and compensation reaches its maximum by the 30th–60th day after the operation.
-
3.
Local instrumental movements (pressure on a high pedal) never reach a high level of accuracy and remain slow by comparison with movements in intact animals.
-
4.
A local instrumental movement of more complex type (pressing a pedal through a hole in the concealing wall), requiring a high degree of accuracy of coordination, is restored to a much lesser degree than the movement of pressing an uncovered pedal.
