Abstract

Golgi-Cox impregnantions of the rat suprachiasmatic nucleus show small dendritic side branches which appear to contact their neurons of origin. Electronmicroscopically a dendrite has been found forming a Gray-type-II synapse with one of its own branches. The arrangement is discussed as a general phenomenon of a feedback connection for temporal limitation of local excitation.
