PSYC62H3 Chapter Notes - Chapter 3: Neurotransmitter Receptor, Ligand-Gated Ion Channel, Catabolism
Document Summary
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 vs. the electrical charge of the environment immediately outside the neuron. Depolarization is a decrease in this difference between charges. Hyperpolarization is an increase in the difference between charge. Electrical potential on a specific part of a neuron. Epsp stimulus that hyperpolarizes a local potential; stands for inhibitory postsynaptic potential. Stimulus that depolarizes a local potential; stands for excitatory postsynaptic potential. Electrostatic attraction is an attraction of ions with opposite charges. Concentration gradient particles of the same type resist being concentrated. Channels that open or close, depending on local potential changes. Temporal summation short succession of excitatory postsynaptic potentials from the same source. Spatial summation excitatory postsynaptic potentials occurring from multiple sources.
