Neurotransmitter Receptors Alter Postsynaptic Membrane Permeability - Neuroscience - NCBI Bookshelf

In 1907, the British physiologist John N. Langley introduced the concept of receptor molecules to explain the specific and potent actions of certain chemicals on muscle and nerve cells. Much subsequent work has shown that receptor molecules do indeed account for the ability of neurotransmitters, hormones, and drugs to alter the functional properties of neurons. While it has been clear since Langley's day that receptors are important for synaptic transmission, their identity and detailed mechanism of action remained a mystery until quite recently. It is now known that neurotransmitter receptors are proteins embedded in the plasma membrane of postsynaptic cells. Domains of receptor molecules that extend into the synaptic cleft bind neurotransmitters that are released into this space by the presynaptic neuron. The binding of neurotransmitters, either directly or indirectly, causes ion channels in the postsynaptic membrane to open or close (Figure 7.1). Typically, the resulting ion fluxes change the membrane potential of the postsynaptic cell, thus mediating the transfer of information across the synapse. Figure 7.1Receptors that mediate the postsynaptic actions of neurotransmitters have two functions. First, specific binding sites on the extracellular side of receptors allow these proteins to detect the presence of neurotransmitters in the synaptic cleft. Second, transmitter-bound receptors alter the ionic permeability of the postsynaptic membrane by virtue of being coupled, directly or indirectly, to ion channels in the postsynaptic membrane. Opening or closing these channels as a result of transmitter binding allows ionic currents to flow, thus changing the postsynaptic membrane potential.
