Parietal lobe

Differences between our own findings and the results obtained in 2014 by Chuang et al. (frontal lobes vs parietal lobes) most probably result from using different cognitive tasks in the MRI scanner (SCWT vs the Flanker Task). It is significant, however, that the results obtained with the magnetic resonance correspond to the results of the neuropsychological examination. The asymmetry of inhibitory processes (which are needed for correct executive control) is reflected in poor performance in…

Dementia affects an estimated 3.8 million people around the world. It is most common in the ages of sixty five-years and older. It is also the sixth leading cause of death in people of the United States, and the fifth leading cause in people over the age of sixty-five. Dementia can start early, and be a very slow process that is evident throughout the rest of the patient’s lives. There are currently no cures for dementia, but there are treatments to help some of the symptoms that go along…

Introduction The Eating Disorders (ED) of Anorexia Nervosa (AN) and Bulimia Nervosa (BN) are two psychiatric disorders characterised similarly by abnormal feeding behaviours whose aetiology currently remains undiscovered. As outlined by the DSM-IV (1994), AN is distinguished as the refusal by an individual to maintain body weight at or above the normal minimum weight for their age and height. Further characteristics include an extreme fear of becoming overweight and a disturbance in the way the…

Early brain imaging studies of musical imagery used PET (positron emission tomogra- phy), which has now been almost completely replaced by fMRI. PET and fMRI each have their pros and cons as methods for functional brain imaging. PET works by com- bining several tricks. Typically, subjects are injected with 2-deoxyglucose, a modified form of sugar that is transported through the bloodstream to cells just like glucose, but cannot be metabolized. As a result, 2-deoxyglucose builds up rapidly in…

As spirituality becomes an increasingly popular tool in the service of mental health, the efficacy of spirituality on positive mental health must be examined. The question arises, not just whether or not spirituality is effective, but also “why or why not?” As a skeptic of spiritual practice, I have been curious about the effectiveness as well as the perceived effectiveness, and how those compare. Understanding this issue will be important in discovering which aspects of spirituality can be…

In the world today, there are about 5000 languages spoken. Where the languages originated from is the unknown factor that the humans have been studying for the past two centuries. Experts have linked the similarity of languages by the shared words, sounds, or grammatical constructions. There are specific names classified for people who speak a certain number of languages. People who speak one language are termed monolinguals. People who speak two languages fluently are termed bilinguals. People…

Augmentative and Alternative Communication, or AAC, is a major method of treatment for aphasia. This treatment allows the individual with aphasia to be a conversation partner and engage in communication that may have been limited before treatment. It is crucial with aphasia to begin fostering communication through AAC very early on in the treatment process. These AAC devices can include low-technology device or high-technology devices (Fried-Oken, Beukelman, & Hux, 2011). One type of AAC…

The Curious Case of Phineas Gage Phineas Gage is among one of the earliest known survivors of a major brain injury. Gage’s brain was severely injured upon working on a railroad near the town of Cavendish, Vermont. With the occurrence of the injury, Gage should have experienced not only major bodily damage, but also severe mental complications. After the incident, Gage barely escaped death, struggling to survive with a large hole in his head. This wasn’t the only issue observed with Gage after…

The ventral tegmental area (VTA) in the midbrain contains DA; which contributes to reward evaluation. The neural linked to reward consists of the basal ganglia, the amygdala, and the hippocampus, as well as to cortical regions like the medial frontal lobe (Textbook). Costa, Tran, Turchi and Averbeck (2014) concluded that monkeys prefer a novel choice option to a familiar one when their DA transporter was blocked. The researchers also showed that DAT blockade led monkeys to assess and choose…

According to www.manneliasinjurylaw.com/distracted-driving/ "As we "share" tasks between parts of the brain, activity in one part will decrease as activity in another part increases; so as we focus on a conversation, for example, activity in the parietal lobe will decrease (by as much as 37% says a study by Carnegie Mellon University) " when it comes to us talking on the phone and driving our attention gets divided sometimes creating what is called inattention blindness which causes the driver…
