27 Mar spike

In neuroscience, a 3-5 millisecond burst of action potential across a synapse that can excite a neuron. If the spike is intense, it will force the electrical potential inside the cell to exceed a threshold and fire or propagate the impulse to other cells. Some action potentials last longer or decay more slowly.
