PSYCH 250 Lecture Notes - Lecture 2: Synaptic Plasticity, Frontal Lobe, Basal Ganglia
Document Summary
7:53 am: a lot of what we know about learning and memory comes from brain dysfunction, can regenerate some of these skills after strokes and other brain trauma because of brain plasticity. Four lobes on the left, four on the right; left and right hemisphere are not interchangeable. Indentations: sulci: gyri: bulges, these allow the brain to fit in the skull. If it didn"t go through thalamus cortical area wouldn"t receive signal. Signal comes into dendrites, cell body decides: pain= neuron cannot close, dendrite is always responding to something outside of it, neuronal tissue is surrounded by glia (support cells) Signal is accepted by auditory cortex as sound, auditory comprehension area: glia, extra support. If a foreign body comes in the glial cells come in to diffuse it. Imprinting: more easily recognizable, how much of what we do is routine, and how much do we carefully pay attention.
