Document Summary
Different types of learning: perceptual & stimulus-response. Perceptual learning: you will never lose this memory, effortful semantic learning, conscious declarative memory, effortless memory. Stimulus-response learning: related to classical and operant conditioning. Anatomy and physiology of learning and memory: hippocampus essential for human memory. Compact structure within temporal lobes one on each side. Referred to as ca (latin name: cornu amonis) Info come from entorhinal cortex along perforant path into hippocampus: what fires together, wires together if two cells active @ same time, connection between them is enhanced, recall: neurotransmitters signal from one cell to the next. Neurotransmitter release chemicals that diffuse over synaptic cleft to bind to postsynaptic membrane, where series of events can lead to action potential. Ampa opens up channel that allows ions to move in (causes depolarization of postsynaptic cells: important for depolarization. Where and when: localization dendritic spines, individual synapses, neurons, cam kinase 2 localized in particular regions of neuron, second messenger molecule.
