Question

​What does synaptic transmission require (in the great majority of cases)?

Quizplus · Accepted Answer

Synaptic transmission requires the release of a chemical, known as a neurotransmitter, from the presynaptic neuron that then acts on the postsynaptic neuron to transmit the signal. While some synaptic transmissions may require synthesis of a new protein or involve electrical transmission, in the great majority of cases, the release of a chemical neurotransmitter is the key step in synaptic transmission. Mechanical vibration is not typically involved in synaptic transmission.
