PSYC62H3 Chapter Notes - Chapter 3: Mesocortical Pathway, Frontal Lobe, Raphe Nuclei
Document Summary
Neurotransmission transmission of information between neurons (pg. Typically involves a neuron releasing neurotransmitter into a synapse, which allows them to act on sites on another neuron. Electrical events within a neuron & release of neurotransmitters. Electrical transmission - series of electrical events that begin at an axon hillock and proceed down the length of an axon (pg. Electrical potential - difference between the electrical charge within a neuron versus the electrical charge of the environment immediately outside the neuron: normally, electrical charge within a neuron is negative compared to the outside environment. Depolarization - reduced difference between the positive and negative charges on each side of a membrane. Hyperpolarization - increased difference between the positive and negative charges on each side of a membrane. Local potential - electrical potential on a specific part of a neuron: changes in response to events within a neuron and with communication from other neurons.
