In neuroscience, the threshold potential is the critical level to which a membrane potential must be depolarized to initiate an action potential. This means that when the inside of a neuron becomes less negative (or more positive) relative to the outside, and it reaches a certain voltage level, an action potential is triggered. This voltage level is known as the threshold potential. It is a crucial concept because it helps to ensure that neurons only transmit signals when they are sufficiently stimulated, thus preventing random or unnecessary firing which could lead to erroneous signaling within the nervous system. read more >>

In neuroscience, the threshold potential is the critical level to which a membrane potential must be depolarized to initiate an action potential. Threshold potentials are necessary to regulate and propagate signaling in both the central nervous system (CNS) and the peripheral nervous system (PNS).read more >>
