Document Summary

Introduction: thumbtack entering your foot converted to neural signal specialized ion channels of the sensory nerve endings allow positive charge to enter the axon if this depolarization reaches threshold, then ap generated for info to be processed by rest of nervous system, necessary that neural signals passed on to other neurons such as motor neurons that control muscle contraction process of information transfer at the synapse is called synaptic transmission physical nature of synaptic transmission was argued for almost a century one hypothesis was that it was simply electrical current flowing from one neuron to the next existence of such electrical synapses was finally proven another hypothesis, was that chemical neurotransmitters transfer info from one neuron to another at the synapse = chemical synapse chemical synapses comprise the majority of synapses in the brain synaptic transmission is a large and fascinating topic.
