In the nervous system, a synapse is a structure that permits a neuron (or nerve cell) to pass an electrical or chemical signal to another neuron or to the target effector cell. Synapses are essential to the transmission of nervous impulses from one neuron to another. Neurons are specialized to pass signals to individual target cells, and synapses are the means by which they do so.

Nettet22. feb. 2024 · Synapse formation is thought to involve bidirectional signaling by proteins that bind to each other across the synaptic cleft. Sando et al. used conditional genetic tools and in vitro assays to investigate the mechanisms of synapse formation. They found that synapse formation in the mouse hippocampus requires latrophilins.

NettetWithin the innervation provided by the spiral neurons, we observed presynaptic vesiculated nerve endings that form reciprocal ribbon-afferent/efferent synapses with inner hair cells. These intracochlear presynaptic fibres are characteristically located between adjoining inner hair cells, on the modiolar side, low and close to the supporting cells.
