The Passage of a Nerve Impulse
Image Description:
The neuron constantly sums up how often and from how many different neurons messages arrive. The outcome of these summations determines whether the neuronal trigger threshold is exceeded and whether the neuron forwards the message.
Temporal summation (several impulses from one neuron over time).
Spatial summation (impulses from several neurons at the same time).
Action potential travels along axon.
