[Comparative characteristics of the background activity of neurons from several regions of the cerebral cortex of unanesthetized cats].
Neuronal background activity in associative (area 5) and certain projection regions (SI, AI, AII) of the cerebral cortex was studied in curarized cats. Different types of the neuronal activitke intervals distribution and autocorrelation function. All these statistical parameters indicated that the background activity of associative neurons significantly differed from that of projective field neurons. Bursts generation was the main peculiarity of the background activity of auditory cortical neurons. According to all the parameters studied the level of the background activity in the somatic sensory cortex was lower. The probable functional significance of these differences is discussed.
