Structure of the synaptic junctions in the rat sensorimotor cortex: freeze-etching study of neuronal gap junctions.
The membrane structure of neuronal gap junctions in the rat sensorimotor cortex was examined using freeze-etched replicas. The gap junction coupling was found between large, probably non-pyramidal neurons and dendrites, and was mostly associated with membrane specializations indicative of the contact zone of an asymmetric synapse or a puncta adhaerentia. The validity of freeze-etching method of identification and analysis of neuronal gap junctions as a feature of the synaptic organization in the rat sensorimotor cortex is discussed.
