Document Summary

Coronal: cross section dividing front and back (lateral to medial cut) Horizontal: cross sections dividing top and bottom (anterior posterior cut) Sagittal (midsagittal if in middle): cross section dividing left and right (anterior to posterior, and superior to inferior) Anatomical techniques: slicing the human brain, viewing macrostructures with the human eye or microstructures with a microscope, appropriate for cadavers. Provides high resolution images of the human brain (or other organ/part: problems. Provides and image of the structures but does not indication their functions. Does not provide image of the active brain. Human stimulation: trans-magnetic stimulation (tms, deep brain stimulation (dms) Functional techniques: pet (positron emission tomography, advantage. Provides an image of the function of various structures of the brain. Indicates which areas are active (and require glucose) for a task to be completed: disadvantage. Requires deoxyglucose to be injected into the blood. The pet provides an image of all the brain areas that were active within the last 1-2 minutes.
