Stroke is the number one disabler and number three killer of the cerebral cortex of the brain. Jill had experienced a rare form of stroke‚ which had left her with a clot the size of a golf ball in her head. Her left hemisphere was very heavily damaged and she was working with solely with the remaining right hemisphere. Between

can cause rapid weight gain. A person with a dysfunctional hypothalamus can have an appetite that is never satisfied‚ leading to over eating. The damaged hypothalamus can interfere with losing weight. Cerebellum which looks like a miniature cerebral cortex‚ lies at the base of the brain. Cerebellum primarily regulates posture‚ muscle tone‚ and muscular coordination. The cerebellum also stores memories related to skill and habits. Without the cerebellum‚ tasks like walking‚ running‚ or playing catch

After sound reaches the eardrum‚ it sets into motion of a complex combination of mechanical‚ chemical‚ and neural events in the cochlea‚ brain stem‚ midbrain nuclei‚ and cortex that result in a percept. The cerebellum plays a role in remembering the “settings” that can be used for synchronizing to music as people hear it‚ and it can recall these “settings” when people need it. The basal ganglia are the most important organ

MARIJUANA’S SHORT AND LONG TERM EFFECTS ON THE BRAIN Millions are abusing marijuana every day. In fact‚ 1 out of 7 high school students smoke marijuana more than once a day.

Marijuana can effect these two areas emotionally or physically. Also in some cases physical damages causes the emotional response. Although most public information

Materials The experiment measured participants response to stimulus‚ determining whether the cerebral hemispheres can communicate. Each test consisted of materials (a) the screen‚ and (b) the object. Being shown a word in either visual field tested the participants capability to process the visual stimulus‚ and share information between the cerebral hemispheres. Procedure Participants were positioned

resembles an afterimage from staring at a bright light‚ but it represents changes in orientation perception rather than in color or brightness. Most modem explanations of the MTAE are loosely based on the feature-detector model of the primary visual cortex (V1)‚ which characterizes this area as a set of orientation-detecting neurons. Experiments showed that these neurons became more difficult to excite: repeated presentation of oriented visual stimuli‚ and the desensitization persisted for some time

The limbic system and prefrontal cortex play an extensive role in human behavior. The limbic system is a set of structures within the brain that controls human emotions and memories; intensifying during puberty. On the other hand‚ the prefrontal cortex is responsible for regulating behavior and thought analysis. This is developed later than the limbic system which has already begun developing during puberty as stated earlier. Due to the differences in developmental time‚ the extremities such as‚
