Document Summary

Answers to before you go on questions: describe how studies of people with brain damage and eegs have contributed to our knowledge of the brain and nervous system. Patients with localized brain damage often experience the loss of some function, which gives researchers clues about what certain brain regions do when they are undamaged. Certain neuroimaging methods, including positron emission tomography (pet) and functional magnetic resonance imaging (fmri), allow for the detection of uptake molecules so that the specific and precise brain areas of increased activity can be identified. Neurons, or nerve cells, are the fundamental building blocks of the nervous system. There are a number of types of glia including astroglia, oligodendroglia, schwann cells, ependymal cells, and microglia. (this question asks you to name only three types of glia, but the answer here gives you information about all the types).
