Superactivation at synapses?

Nerve cells have to react extremely quickly, but depending on the task they are supposed to perform they often need to work more slowly. Berlin scientists have now shown that a receptor in the synapse can adapt to follow ...

Action potential

An action potential (or nerve impulse) is a transient alteration of the transmembrane voltage (or membrane potential) across an excitable membrane generated by the activity of voltage-gated ion channels embedded in the membrane. Action potentials play multiple roles in several types of excitable cells such as neurons, myocytes, and electrocytes. The best known action potentials are pulse-like waves of voltage that travel along axons of neurons.
