자가 시냅스는 신경세포가 스스로와 형성하는 시냅스입니다. 이들은 단기 아날로그 메모리 저장고로서 작용하는 것으로 여겨지고 있습니다.[1]
Strictly speaking, an autapse is a synapse from the axon of a neuron to one of its dendrites, that is, from its output to its input. However, structures have been found via Eyewire formed as a looped branch in a dendrite that may be either autapses or self-touches (i.e. not a synapse at all).[2] In EyeWire's 2D view, these generally appear to be branches that move away from the main branch, approach it again, but only touch again along a cell membrane.

History
Autapses have been known since at least 1972.[3]
