postsynaptic membrane

The postsynaptic membrane is a key part of how nerve cells communicate with each other. When a signal travels down a neuron and reaches the end, it releases chemicals called neurotransmitters into the synaptic gap—the space between neurons. The postsynaptic membrane, located on the receiving neuron, contains special receptors that detect these neurotransmitters. When the right neurotransmitter binds to its receptor, it triggers changes in the receiving neuron, which can lead to a new signal being generated and passed on. This process is essential for brain function, affecting everything from movement to mood.
