Unit activity of the somatosensory cortex was studied in chronic experiments on cats during alimentary instrumental conditioned reflex performance and elaboration of conditioned inhibition (CI). First presentations of the CI signal at the beginning of CI formation caused, due to orienting reaction to a new stimulus, a levelling of the response of the neurones to the positive conditioned signal included into the CI complex. At the stage of consolidated CI, this depression proceeded gradually during the development of conditioned inhibition caused by consecutive presentations of the nonreinforced CI combination. Two groups of neurones were involved in the process of the CI performance: one of them being the same which was activated also in response to positive stimulation during performance of the conditioned response, and the second one being areactive to the positive conditioned stimulus but reducing the frequency of the background activity.
在对猫进行的慢性实验中，研究了在食物性工具性条件反射形成和条件性抑制（CI）建立过程中体感皮层的单位活动。在CI形成开始时，CI信号的首次呈现，由于对新刺激的定向反应，导致神经元对包含在CI复合体中的阳性条件信号的反应趋于平稳。在巩固的CI阶段，在由非强化CI组合的连续呈现所引起的条件性抑制发展过程中，这种抑制逐渐进行。两组神经元参与了CI执行过程：其中一组与在条件反应执行期间对阳性刺激也有反应而被激活的神经元相同，另一组对阳性条件刺激无反应，但降低了背景活动的频率。
