Autapse
An autapse is a chemical synapse from a neuron onto itself. It can also be described as a synapse formed by the axon of a neuron on its own dendrites, in vivo or in vitro.
Discovered in 1972,[1] they were originally thought to be a biological curiosity, but are now assumed to serve some purpose[2] (though their general function remains unknown), as they have been found to be common in some circuits of the visual cortex.[3]
