Impulse anatomy definition
WitrynaIf a neuron responds at all it responds completely; all impulses are the same strength; the greater the intensity of a stimulus, the more impulses per second Refractory Period short time following an impulse when another stimulus will not trigger another impulse Synapse a junction between any two communicating neurons Synaptic cleft WitrynaIncoming signals can be either excitatory – which means they tend to make the neuron fire (generate an electrical impulse) – or inhibitory – which means that they tend to keep the neuron from firing. Most …
