[Structural differences between the desmosome-like contacts in the chemical and afferent synapses of Mauthner neurons in the goldfish].
Comparative ultrastructural investigation of the desmosome-like contacts at chemical and mixed afferent synapses of the goldfish Mauthner neurons was carried out. It was revealed that these contacts at mixed synapses differed from those at chemical ones by thin transverse fibrillar bridges which cross the gap and connect two adjoining membranes of the junction. We suppose that these crossbridges together with gap junctional connexons may serve as a substrate for electronic coupling at mixed synapses demonstrated earlier.
