Neurotransmitter

neurotransmittersexcitatory neurotransmitterneurotransmitter system
A neurotransmitter receptor (also known as a neuroreceptor) is a membrane receptor protein that is activated by a neurotransmitter. They are a group of transmembrane ion channels that are opened or closed in response to the binding of a chemical messenger (i.e., a ligand), such as a neurotransmitter.
Neurotransmitters are released from synaptic vesicles in synapses into the synaptic cleft, where they are received by neurotransmitter receptors on the target cells.

Chemical synapse

synaptic cleftpostsynapticpresynaptic neuron
In postsynaptic cells, neurotransmitter receptors receive signals that trigger an electrical signal, by regulating the activity of ion channels.
These molecules then bind to neurotransmitter receptors on the postsynaptic cell.

Inhibitory postsynaptic potential

inhibitoryIPSPinhibitory synapses
These receptors can also be inhibited by neurotransmitters like GABA and glycine.
Inhibitory presynaptic neurons release neurotransmitters that then bind to the postsynaptic receptors; this induces a change in the permeability of the postsynaptic neuronal membrane to particular ions.

Excitatory postsynaptic potential

excitatoryEPSPexcitatory postsynaptic potentials
Ionotropic receptors are also called Ligand-gated ion channels and they can be excited by neurotransmitters (ligands) like glutamate and aspartate.
When an active presynaptic cell releases neurotransmitters into the synapse, some of them bind to receptors on the postsynaptic cell.

Synapse

On presynaptic cells, there can be receptor sites specific to the neurotransmitters released by that cell (see Autoreceptor), which provide feedback and mediate excessive neurotransmitter release from it.

Membrane potential

LGICs are also different from voltage-gated ion channels (which open and close depending on membrane potential), and stretch-activated ion channels (which open and close depending on mechanical deformation of the cell membrane).
A large subset function as neurotransmitter receptors—they occur at postsynaptic sites, and the chemical ligand that gates them is released by the presynaptic axon terminal.

Neurotransmission

Cotransmission allows for more complex effects at postsynaptic receptors, and thus allows for more complex communication to occur between neurons.

Receptor (biochemistry)

A neurotransmitter receptor (also known as a neuroreceptor) is a membrane receptor protein that is activated by a neurotransmitter. Therefore, a membrane receptor is part of the molecular machinery that allows cells to communicate with one another.
