Cat scan takes xray pics from all angles to make 3d model of brain (bleeding) Mri shoots magnet through head to see brain from half cut. Single cell recording scans brain to observe movement of each cell. Electroencephalography studies sleep patterns electrodes on head measures surface energy. Pet scans pics of each layer of brain, detects glucose activity. Dti looks at neural connections in the brain, like a jellyfish.
