Abstract:
The synaptic connections of the axon initial segment (IS) of retrogradely labeled corticocollicular neurons in the rabbit visual cortex were studied using the HRP-EM method. Identified IS showed relatively few synaptic boutons unevenly distributed along their surface. All these axo-axonic terminals contained pleomorphic vesicles and formed symmetrical synaptic junctions with the IS. The possible origin and chemical nature of these synaptic boutons are discussed.
