Web21 aug. 2024 · These proteins incorporate an ion channel within their molecular structure. When a neurotransmitter binds to its postsynaptic receptor it causes ion channels to open, or less frequently, to close. This movement of ions across the neuronal membrane generates an electrical current, the postsynaptic current (PSC), which in turn changes … WebIonotropic receptors (also known as ligand-gated ion channels) play an important role in inhibitory postsynaptic potentials. A neurotransmitter binds to the extracellular site and opens the ion channel that is made up of a membrane-spanning domain that allows ions to flow across the membrane inside the postsynaptic cell. designs by me charms
