Abstract

The interrelationships of stimulation thresholds in the auditory cortical areas AI, AII, and Ep were studied in chronic experiments on cats. The linear correlation existed between the fluctuations of excitation levels of the auditory areas. The correlation coefficients could be changed by sound stimulation. Administration of amphetamine and aminazine as well as anodal polarization of the midbrain reticular formation revealed participation of the latter in establishing of the above interrelationships.

摘要

在对猫进行的慢性实验中，研究了听觉皮层区域AI、AII和Ep的刺激阈值之间的相互关系。听觉区域兴奋水平的波动之间存在线性相关性。相关系数可通过声音刺激而改变。给予苯丙胺和氯丙嗪以及中脑网状结构的阳极极化表明，后者参与了上述相互关系的建立。
