Neurons that pick-up information from the environment. the charge of the neuron when there is no signal is running through it. When a neuron"s receptors are stimulated, a charge runs down the axon. Chemicals released by the neurons that stimulate the next neuron. What is hierarchical processing? on representations in the person"s nervous system.
