Document Summary

Coronal (vertical across side)-sagittal (vertical from top)-horizontal (across side) Viewing macrostructures w the human eye or microstructures w a microscope. Appropriate for cadavers (bodies of those executed back then) Advantage: provides high resolution images of the brain. Provides an image of the structures but does not indicate the function of the structure: very expensive, resolution is limited (cannot see single cells, but now we can see microstructures (only for research purposes) In the clinical setting: observe functions lost bc of brain injury (trauma, stroke, tumours, etc. ) Most of these studies were done during the war (lots of patients) Problem: human brain injuries are often widespread and not highly specific. In the experimental setting: lesion a specific part of animal brains to determine its function. Stimulate a specific area of the brain to observe the function it controls. Problems: in many cases, it is difficult to know just what an animal is experiencing. Higher mental states may well differ across species.
