Document Summary
Patients with localized brain damage often have loss of some particular function. The type of loss of function then suggests what the brain region did before it was damaged: recording electrical brain activity through multiple electrodes attached to the surface of the scalp. Scientists have used electroencephalograms, or eegs, as a non- invasive way to measure or learn about the activity of our brains during certain states (awake and asleep) and during certain behavioural tasks: animal studies. Studies on animal nervous systems have made it possible to look closely at parts of functioning brains. Transcranial magnetic stimulation (tms) delivers an electromagnetic pulse to a targeted brain area, disrupting localized brain activity in a conscious person: neuroimaging techniques have been developed to study brain activity. These methods include computerized (or computed) axial tomography (cat or ct), magnetic resonance imaging (mri), and diffusion tensor imaging (dti): ct scans - produce clear, detailed, two-dimensional x-ray images of the brain or other organs.
