[Participation of the substantia innominata in differential inhibition in the cat]. / Uchastie bezymiannoi substantsii v differentsirovochnom tormozhenii u koshek.

Elaboration of differentiation, its disturbance resulting from bilateral lesion of the substantia innominata and its subsequent restoration was studied in cats. Ablation of the substantia innominata was accompanied by disturbances of the internal inhibition. The initial level, that before the operation, was not obtained even after a long training. It is suggested that substantia innominata modulates cortical activity and its ablation prolongs the afferent synthesis.

[Conditioned reflexes before and after lesioning the substantia innominata in the cat]. / Uslovnye refleksy do i posle povrezhdeniia bezymiannoi substantsii u koshek.

It has been shown that bilateral lesion of the substantia innominata has caused temporary depression of unconditioned and conditioned alimentary reflexes, disturbances of the elaboration and performance of conditioned reflexes. It is suggested that the latter produced by the operative memory disturbances.
