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.
Star-shaped glial cells in the CNS are collectively known as astrocytes. 'Astro' implies 'star' and 'cyte' refers to 'cell'. Hence, we get 'astrocyte': a star-shaped cell. These glial cells are responsible for a lot of important things in the central nervous system; most notably, they are part of the blood-brain barrier. Tiny little feet leave the astrocyte and help to encircle the vessels that make up the blood-brain barrier, which is a barrier that helps to prevent undesirable substances from entering the brain via blood vessels.
