GlossaryNeurotransmitter Receptor

protein on neuron surface that binds neurotransmitters to trigger responses

A neurotransmitter receptor, also known as a neuroreceptor, is a protein located on the surface of a neuron (nerve cell) that binds to specific chemicals called neurotransmitters. When a neurotransmitter binds to its receptor, it triggers a response in the neuron, such as initiating an electrical signal or altering cellular activity, which is essential for communication within the nervous system.
