[The cholinergic function of the bipolar neurons of the human cerebral cortex]

In layers II, III, V and VI of the 4th and 17th cytoarchitectonic zones of the main brain cortex, bipolar neurons with a positive reaction to cholinacetyltransferase were found. It is concluded that the bipolar neurons may metabolize acetylcholine to be cholinergic in their mediator specialization.
