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.
The brain is made up of more than just nerve cells (neurons). Although there are about 100 billion neurons in the brain, there may be about 10 to 50 times that many glial cells in the brain. Neurons CAN generate action potentials...glial cells CANNOT. 2  However, glial cells do have a resting potential. 3  Neurons HAVE synapses that use neurotransmitters...glial cells do NOT have chemical synapses. 4  There are many MORE (10-50 times more) glial cells in the brain compared to the number of neurons.
