Conclusions

  1. 1.

    Investigation of interneuronal relations in the cat sensomotor cortex revealed different types of dependence in the discharge of individual neuron pairs both during their spontaneous activity and in the after-period of thalamic stimulations.

  2. 2.

    Repeated isolated stimulations of the thalamic nuclei (VPL and VL) led to marked transformation of the “excitatory” component of the “inhibitory—excitatory” relationship dur1ing discharge of two neighboring neurons. The transformations differed in cases of stimula tion of the two different nuclei: whereas stimulation of VPL mainly weakened the “excitatory” component of the “inhibitory—excitatory connection,” stimulation of VL usually distinctly enhanced it.

  3. 3.

    The character of interneuronal influences formed during the action of isolated thalamic stimulations underwent further modification in the course of combined stimulations of the same nuclei.

  4. 4.

    Changes in interneuronal dependence arising as a result of prolonged thalamic stimulation could last for several minutes after cessation of the stimulations.
