PSY397H5 Lecture Notes - Lecture 4: Gyrus, Entorhinal Cortex, Episodic Memory
Document Summary
Movement high concentration to low concentration diffusion, movement, resonation that cause ions to move in random, entropy to organize. Cyclase activated enzyme that will release, kinase positive potassium flow. Electrophysiological tools - electrodes, stimulation, firing and action potentials. Pharmacological tools - primarily for neurons in hippocampal formation. Behavioural tools - conditioning, learning tasks, and behavioural tests to tap into the hippocampal formation. Plasticity pyramidal cells, most plastic neurons and very sensitive and are the first to die. Relevance show as hippocampal specific alzheimer"s first to be affected is the episodic memory, and spatial learning. Connected to every part of the brain and perceives every signal. Pieces are memories that are scattered in remote locations in the cortex hippocampus keeps track of the pieces and what belongs to each other (many puzzles) Common firing at location will give the image, modifying synaptic connection hippocampus can rewire the brain and connect the dots.
