Neurons with presynaptic somatic protrusions in the visual cortex of monkeys.
In layer IV of the visual cortex of two primate species three small neurons were found that gave rise to short presynaptic somatic protrusions. The protrusions contained a cluster of predominantly round vesicles and established asymmetrical synaptic contacts with the characteristics of Gray's type 1 terminals.
