Document Summary

330 mid-term: 4 cerebral hemispheres (frontal=controls voluntary movement, parietal=mediates attention, temporal=auditory processing, occipital=visual processing). Animal methods (recording electricity inside of skull: galvani zapped the frog legs and came up with model that animals run on electricity. Single cell recording technique (glass tubule inserted into a cell and picks up the electrical impulse. Is the best way to see if brain is bleeding/look at tumours and figure out how to treat. Functional neuroimaging (looking at changes in brain from 1 second to the next: mosso hypothesized that blood flow is affected in head by thoughts (cuz when brain is active, then neurons need to be oxygenated, therefore needs blood). Pet scanners are expensive. fmri: magnetic pulse detects vibration frequency of element u want it to (ie: hydrogen). Take picture of brain using x-rays that rotate around the body. Tomography assembles the slice images and makes 3d structural image of brain.
