Document Summary
Studying autopsy tissue gives insight into the physical structures of the brain but very little information about their function. Testing the behaviour of patients with localized brain damage is a common practice amongst neurophsycologists to figure out what role a small area of the brain performs. Electroencephalograms (eeg"s) measure brain activity across a large section of the scalp. Related potentials (erp) help to make it useful for figuring out how quickly the brain reacts to something but it is not a useful tool for determining where in the rain said reaction takes place. Animal studies allow us to study brains of living beings in ways that we can"t study humans (ex: lesioning). Transcranial magnetic stimulation (tms) delivers an electromagnetic shock to a conscious person"s brain causing a temporary lapse in the function of that area. It can be used to see if an area plays a role in certain functions.
