Explain one study related to localization of function in the brain (Sperry) Command Term: Explain reasons or causes. Localization of function refers to the belief that specific areas of the cerebral cortex are associated with specific physical or behavioral functions. Examples of case studies to prove how specific locations of the brain can be affected and have an impact on behavior are demonstrated by the HM and Phineas Gage incident. In 1848‚ when Phineas Gage was tampering iron to press

cortical networks‚ or most likely by both. As the latency of the transient gamma band response is about 30–70 ms after stimulus onset this plastic reorganization of auditory neural networks is likely to take place at the level of the primary auditory cortex.”(Pantev 2147-2148). To summarize this‚ there is infact a correlation between the plasticity of your brain and learning to play a musical

medial and central nuclei‚ and the intercalated cell clusters (ITCs). The basolateral complex has three parts: the lateral‚ basal‚ and accessory-basal nuclei. Sensory information‚ which arrives directly from the hippocampus and the primary auditory cortex‚ goes mainly to the lateral nucleus. The basolateral complex then processes this information and sends it as output to the centromedial nucleus of the amygdala (“Basolateral

Addicts‚ the most common finding in this group is low activity in the prefrontal cortex‚ likely due to low levels of dopamine. The PFC is involved in judgment‚ impulse control‚ planning‚ follow through‚ decision making‚ and paying attention. This type is often seen with ADD and ADHD and is more common in males. Type Three is Impulsive-Compulsive Addicts SPECT scans here tend to show low activity in the prefrontal cortex‚ likely due to low dopamine and too much activity in the anterior cingulate gyrus

Depression Depression can be a very difficult and painful experience that affects not only the individual suffering from it‚ but also the people around them. As a biological psychological factor‚ genetics play a big role. Mood disorders are inheritable for some people. Those that are susceptible to mood disorders can have an early age of onset‚ a greater rate of suffering other disorders in addition to depression and an increased risk of recurrent illnesses. However any genetic factors that are

1. Define and identify general characteristics of cerebral palsy (CP). Cerebral palsy is a condition in which permanent disabling symptoms are a result of damage to the motor control areas of the brain. Characteristics of cerebral palsy include abnormal reflex development‚ seizures‚ speech and language disorders‚ sensory impairments‚ bone growth‚ and respiratory conditions. 2. There are three neuromotor classifications (types) of CP. Identify the area of the brain affected in each as well as a

given age‚ as well as aspects of muscle and bone strength. The main areas of the brain involved in motor skills are the frontal cortex‚ parietal cortex and basal ganglia. The dorsolateral frontal cortex is responsible for strategic processing. The parietal cortex is important in controlling perceptual-motor integration and the basal ganglia and supplementary motor cortex are responsible for motor sequences. Nutrition and exercise also determine strength and therefore the ease and accuracy with which

The differences in the structure are in certain regions‚ for example the cerebrum‚ frontal and medial paralimbic cortices‚ the fronto –medial cortex‚ the amygdala‚ and the hypothalamus. These areas of the brain control different behaviors as well as actions and reactions that can contribute to criminal

the case of the drug targeting only the left motor cortex‚ the loss of control over the muscles and the inability of doing everyday things like dressing yourself‚ would be the most likely consequence. Some other consequences that would be a possible result of the “miracle” drug are hearing loss and inability to speak. If this was the case‚ hearing loss would mean that the subject’s temporal lobe was damaged because that is where the auditory cortex is. And if the subject was incapable of speaking that
