PSY290H1 Lecture Notes - Lecture 4: Tyrosine Hydroxylase, Electrooculography, Knockout Mouse
Document Summary
Trying to relate human psychology to neurology. Cognitive neurology --> how thinking/cognition change after injury --> now done by detailed analysis by studying behaviour (change in function) Visualizing brain structurally --> *major part of neurology. How physics used to visualize chemical, electo (electroencephalography), aspects of brain --> pet, mri, ct scans. Other major approach to studying brain = going into brain --> mostly involves animals (can"t do invasive techniques w/humans) -->*rodents --> combined with: Animal psychology --> need to use neurochem and pharmacology --> the biopsychological approach (invasive techniques on animals) We talked about recording from single neurons from single dish --> studying act. Neurophysioology in humans --> electrodes onto surface of, or within (req. poten, neuron es. Absorbtion of x-rays occurs mainly in bones --> thus imaging shows powerfully bone tissue. Head: visualize cranium --> grey matter & white matter vs. ventricles. Ventricles less absorbing of x-rays than skull.
