Web• Postsynaptic potentials (PSPs) are elicited on the cell body and dendrites • PSPs are conducted decrementally to the axon • When the summated PSPs exceed the threshold of excitation at the axon, an action potential (AP) is triggered • The AP is conducted non-decrementally down the axon to the axon terminal • Arrival of AP at the axon terminal … WebAn action potential is an event that is specific to excitable cells like neurons or muscle fibers. It involves a rapid and short-lasting rise in the electrical potential, immediately followed …

An action potential is the …
WebThus, action potentials transmitted over a sensory receptor’s afferent axons encode one type of stimulus, and this segregation of the senses is preserved in other sensory circuits. For example, auditory receptors transmit signals over their own dedicated system, and electrical activity in the axons of the auditory receptors will be interpreted by the brain as …
