Summary
Somato-dendritic synaptic contacts were found between the perikaryon of stellate neurones and the dendrites of, presumably, pyramidal and pearshaped neurones in the optic tectum of the frog. According to the electron microscopic findings, the soma of stellate neurones is the presynaptic element. In a number of cases axo-somatic synapses were seen on the same neurones within a distance of 1–2 μ from the somato-dendritic synaptic contact. The synapsing axons are, probably, of tectal origin. It is assumed that the somato-dendritic synapsis is inhibitory in nature.
