Document Summary

Meg magnetocephalography: captures changes in magnetic fields, can localize the activity of the cortex better than eeg can, eeg: millisecond association by the image::meg: way better triangulation and depth, squid: high resolution magnetic field sensitization techniques. Brain stimulation: electrical current is used to stimulate brain tissue. Intracranial brain stimulation: deep brain stimulation (dbs, electrodes implanted in the brain to stimulate the tissue, used as a treatment for parkinson"s disease. Improve cognition, more movement, etc: tms transcranial magnetic stimulation, stimulation of the brain using a magnetic stimulator. Magnetic stimulator small wire coil in the shape of a figure 8: interferes with the magnetic environment of the cortex, noninvasive. No permanent damage measurable: can be used to map. Functional brain imaging: provides a way to look at the brain w/o using dangerous or unpleasant procedures, pet scan, more active area, more blood, more oxygen and more removal what.
