Video: Techniques to Study the Brain and Behavior. Why do you behave the way you do? Human behavior begins in the brain. To study the brain, psychologists use a variety of tools, like EEG, PET and CAT scans, MRI, DTI, and studying pathology in individuals.
What Are Glial Cells. Glial cells are known by many names-neuroglia or glia to name just a few. In the past, they were sometimes mistaken for brain cells but they're completely different. They're nervous system cells that are found in your brain and spinal cord.
Images of glial cells. (a) Astrocytes and (b) oligodendrocytes are glial cells of the central nervous system. Glial cells support neurons and maintain their environment. Glial cells of the (a) central nervous system include oligodendrocytes, astrocytes, ependymal cells, and microglial cells. Oligodendrocytes form the myelin sheath around axons. Astrocytes provide nutrients to neurons, maintain their extracellular environment, and provide structural support.
