PSYCH 220 Lecture Notes - Lecture 3: Neurotransmitter Receptor, Sodium Channel, Fluid Compartments
Document Summary
Chapter 3: the generation, transmission, and integration of neural signals. Synaptic vesicles small spheres in presynaptic axon terminals that contain neurotransmitters: neurotransmitters specialized chemical released in response to electrical activity in the axon. Neurotransmitter receptors specialized receptors in the postsynaptic membrane that react to neurotransmitter molecules: receptors are specialized for each neurotransmitter. Neural plasticity the continual remodeling of neuronal connections: strengthen neural transmissions by strengthening synaptic connections or packing more neurotransmitter into each vesicle, neural transmissions can deteriorate. Microglia will come clean up the debris: small pruning that happens throughout the lifetime. Reuptake taking the excess neurotransmitters back up into the presynaptic cell. The amount of neural transmitters vesicles is always different: the amount released is different, enzymes can break down neurotransmitters, some people have less neurotransmitters or faster reuptake. Neurotransmitters must bind to a receptor to have any effect. Neurophysiology the study of life processes of neurons.
