PSYC 304 Lecture Notes - Lecture 4: Inhibitory Postsynaptic Potential, Neurotransmitter, Muscarine
Document Summary
Describe the resting membrane potential and its ionic basis. Explain how an action potential is normally triggered. Describe how action potentials are conducted along myelinated and unmyelinated axons. Discuss the structure and variety of synapses. Name the synapse upon which the classic view of synaptic transmission was based. Explain each of the many ways in which the classic view of synaptic transmission was incorrect. Explain what is meant by a tripartite synapse". Ephaptic coupling: the space between cells are so small, so signal from one cell will travel to adjacent cells (electrical current) Way they used to measure resting membrane potential. Put sharp electrode into the body of a cell and place a larger electrode outside. Patch clamp recording: updated method from intracellular recording. Take fine tipped glass electrode and approach a cell; sucks off a part of the cell so that the inside of the cell is continuous with the fluid in the electrode.
