Document Summary
Neuroimaging - tech. that allow for studying brain activity and structure by obtaining visual images in awake humans. Neurons: cells in the nervous system that communicate with one another (using electrical/chemical signals) to perform information-processing tasks (allows nervous system to work) Glia: cells that help support neurons & make up the nervous system. Oligodendroglia: provide myelin to speed up transmission of neurons. Microglia: clean up dead cells and prevents infections in the brain. Electroencephalograms (eegs) - used to learn about brain in certain states (awake/asleep) or during certain behavioral tasks. Animal studies - studies on animal nervous systems helped us look closely at parts of functioning brains. Structural neuroimaging techniques: use advanced tech. to create images of the living, healthy brain - structure of brain computerized axial tomography (ct or cat) scan. Magnetic resonance imaging (mri) (clearer image than cat scan) Functional brain imaging techniques: allow us to watch the brain in action.
