Document Summary
Testing the behaviours of patients with brain damage. Mild trauma brain injury (mtbi); chronic trauma encephalopathy (cte) Recording electrical brain activity (eeg or erp) Neuroimaging techniques that show visual images in awake humans. Pet scan; cat scan; fmri scan; dti scan. The nervous system: the two major types of brain cells are neurons and glia, neurons. Neurons communicate with other cells by producing and sending electrochemical signals. Motor communicates information to the muscles. Interneuron carries information between neurons in the brain and the spinal cord: glia. Glia are involved in various functions, such as forming the blood-brain barrier, producing myelin, and clearing the brain of debris. Astrocytes creates blood-brain barrier, influences communication between neurons, and helps heal brain damage. Oligodendroglia provides myelin to speed up transmission of neurons. Microglia cleans up dead cells and prevents infection in the brain: the structure of neurons. The major structures of the neurons include the cell body, the axon, and the dendrites.
