PS267 Study Guide - Quiz Guide: Carl Wernicke, Purkinje Cell, Paul Broca
Document Summary
Description: linked behaviour to brain structure changes, treat patient throughout life & do autopsies, phrenology: skull bumps = mental traits, aggregate field theory: whole brain participates in behaviour. Localizationist views: left hemisphere = speech disturbance, right hemisphere = visuospatial, watched seizures, damage to inferior frontal lobe in left. Hemisphere = speech production deficits: can"t speak, understand speech, damage to posterior region of left. Hemisphere = speech comprehension deficits: can speak (makes no sense), can"t understand. Fritsch and hitzig: stimulate parts of dog brain & observe. Helmholtz corresponding movements: 52 distinct areas, comparative cytoarchitectonics: how cells differ btwn brain regions. Individual neurons: stain individual neurons, syncytium: whole brain = continuous tissue mass, the neuron doctrine: nervous system made of individual cells, electrical transmission from dendrite axon, described nerve cell, discovered purkinje cells, velocity (speed) of nerve conduction. Ebbinghaus: mental process (memory) can be measured and analyzed.
