PSYC62H3 Chapter 3: Neurotransmission
Document Summary
Neurotransmission transmission of information between neurons. Involved a neuron releasing chemicals called neurotransmitter into a synapse. Electrical events within a neuron and the release of neurotransmitter. Certain electrical events within a neuron must take place before neurotransmitter can be released. These events are referred to as electrical transmission. Electrical transmission series of electrical events that begin at an axon hillock and proceed down the length of an axon. Electrical potential difference between the electrical charge within a neuron versus the electrical charge of the environment immediately outside the neuron. Normally the electrical charge within a neuron is negative compared the outside environment. Depolarization reduced difference between the positive and negative charges on each side of a membrane (decrease in difference) Hyperpolarization increased difference between positive and negative charges on each side of a membrane (increase in difference) Local potential electrical potential on a specific part of a neuron.
