Postsynaptic Receptor

Postsynaptic receptors are specialized protein molecules embedded within the plasma membrane of the postsynaptic neuron, strategically positioned to receive and interpret chemical signals, known as neurotransmitters, released from the presynaptic neuron. These receptors are the critical transducers of synaptic transmission, converting the chemical signal into an electrical or biochemical response in the postsynaptic cell, thereby enabling rapid and precise communication within neural circuits. Their type, density, localization, and functional state profoundly influence the strength, duration, and nature of synaptic responses, ultimately shaping neuronal excitability and circuit function.
