BRAIN WAVES ANATOMYNeurons generate electrical activity from inside the cerebral cortex. This is a continuous process that is required for human survival. Recorded activity of this process can be understood when electrodes are attached at specific pinpoint positions throughout the scalp. This is known as an EEG. Also called brain wave activity, and EEG pattern expresses the collective activity of literally million of cerebral neurons. During fetal development, brain waves are first activated once the brain has begun to develop the cerebral cortex. Brain wave activity is required for thoughts, emotions, action, and other normal human functions throughout life. A person without brain wave activity is considered brain dead.
BRAIN WAVES FUNCTIONSVariations in the EEG patterns can determine an individual brain’s malfunction. It can indicate trauma, tumors, seizures, infections, lesions, and hematoma. There are 4 distinctive patterns that determine brain wave activity and brain health. The white matter of the cerebrum is thick and deep within the cerebral cortex. It contains brain factors such as dendrites, myelinated dendrites, and neuroglia. These fibers are responsible for the formation of the vast and extensive connections in the brain, which number into the millions. These connections are responsible for communication via electrical impulses to the various parts of the body. There are 3 variations of fiber tracts within the white matter, each aptly named for the direction the impulses travel as well as location which they travel from or to.
BRAIN WAVES DIAGRAM
Association fibers are those which are determined to serve a specific hemisphere and then appropriately conduct the impulses between the specific neurons within that hemisphere of the brain.
Projection fibers form tracks which ascend and descend along the cerebrum. These tracks are known to transmit impulses from the cerebrum to and from various parts of the brain, the spinal cord, and then back to the cerebrum.
