Receptor potential
From Free net encyclopedia
Receptor potential is the transmembrane potential difference of a sensory cell.
A receptor potential is often produced by sensory transduction. It is generally a depolarizing event resulting from inward current flow. The influx of current will often bring the membrane potential of the sensory receptor towards the threshold for triggering an action potential.
