Brain damage

Although located at the back of the eye, the optic nerve is considered a part of the central nervous system due to its role in visual integration and function. The optic nerve transfers visual information from the retina to the vision centers of the brain via electrical impulses. Made of about 1.7 million retinal ganglion cell axons, or nerve cells, the optic nerve encompasses the first portion of the visual pathway: from the retina to the optic chiasm. Dimensions The optic nerve itself is a…

In 1997 Adrian Raine conducted a study that focused on brain abnormalities in murderers that were shown by the use of positron emission tomography (PET). “The aim of his experiment was to see if murderers who pleaded not guilty by the reason of insanity (NGRI) showed signs of brain abnormalities with PET scans. Raine used 41 participants, 39 of which were male and 2 of which were females. The prisoner’s reasons for insanity varied. Six said they were schizophrenic, 23 said it was due to a head…

through the use of a substance, in this case primarily, but not exclusive to alcohol, proper brain function is inhibited causing deficits in memory, thinking, and the ability to store and recall information (Nevid, Rathus, & Greene, 2013). The severity of neurocognitive disorders, on a spectrum from mild to major, depends upon the amount of damage as well as the location of damage due to the fact that different brain areas function in different ways (Nevid, Rathus, & Greene, 2013). Korsakoff ’s…

Is screen time damaging the teen brain emotionally? Ever heard of the Limbic System, Synaptic Pruning, or the Prefrontal Cortex? Synaptic Pruning, the Limbic System, and the Prefrontal Cortex all deal with the brain. In a way, they all have something to do with behavior. Screen time is bad not only for a teens brain, but for their health. The AAP should should not raise the time limited to screen time. Synaptic Pruning is a productive charge in neutral structures by reducing the overall number…

order to make a proper diagnosis and this evidence is obtained through the use of brain imaging techniques that show the changes or damage that are associated with vigorously shaking the baby (Blumenthal, 2002, p. 734). These techniques include “magnetic resonance imaging” (Blumenthal, 2002, p. 734) (MRI) or “computerised tomography” (Blumenthal, 2002, p. 734) (CT) scans, however in terms of detecting damage to the brain as a result shaking baby syndrome, physicians prefer “computerised…

Using music to treat some disease is normal things in the modern century, but how music affects the brain? There’s a real case that I did before. When I was studied at the Min Chi University of Technology, I did an interesting experiment. The professor (Dr. Yi-Lang, Chen) who teach human factor engineering wants us to understand how our brains work by monitoring them in real time with instruments. For example, we used functional magnetic resonance imaging (fMRI) to scanner the tester. When…

“Never one person or groups of people exclusively used more of their left side of the brain or more of the right side” was concluded by Dr. Gayatri Devi, the professor of neurology at New York (“Left brain right brain theory”). This is a reference to the myth that people think they are more dominant on their left side of their brain and vice versa. The split-brain theory, better known as the left-brain, right-brain theory, is a theory that distinguishes people as “left brained” or “right…

+ What Is The Birth Defect, Cerebral Palsy? Cerebral palsy is a group of conditions that affect control of movement and posture. Because of this birth defect it causes damage to parts of the human brain that control movement, when a child is diagnosed or infected he or she cannot move their muscles normally. Symptoms could be mild or severe, the condition stays the same throughout their whole life. With treatment, most children or adults can improve their abilities. Many children have worse…

human interaction still exists. With technology being such a massive factor in everyday life it must have effects on the brain. UCLA scientists have found that key centers of the brain that control decision- making and complex reasoning are triggered while using technology, the results suggest that web search activity may help stimulate and possibly improve functions of the brain (Champeau). Traditionally games such as crossword puzzles were used to preserve cognitive ability, but with the…

The prefrontal cortex is located in the frontal lobe of the brain and can be subdivided into different regions such as the orbitofrontal cortex and the left dorsolateral prefrontal cortex. These areas as a whole are responsible for decision making, controlling emotions and other key social skills, they are also important for dealing with executive functions such as reasoning and planning. Mitchell (2014) claims that ‘the prefrontal cortex represents the pinnacle of evolution as it handles some…
