Cerebral hemisphere

characterized as a neurological communication disorder that demonstrates an impaired ability to plan or program motor movements necessary for speech (Davis, Farias, & Baynes, 2009). AOS is supraotentorial in nature and typically occurs in the left hemisphere (Duffy, 2013). Localization of AOS occurs in the dominant hemisphere’s structures and pathways that are responsible for the planning and programming of speech movements. The plan is what (i.e., motor movements necessary for phonological…

Risk Factors There are several identified genetic and environmental risk factors for pediatric multiple sclerosis. Some of the identified environmental risk factors include exposure to certain viruses, vitamin D deficiency, and second-hand tobacco smoke exposure. The main genetic risk factors involved in development of pediatric onset multiple sclerosis (POMC) is variation in Human Leukocyte Antigen (HLA)-DRB1 *1501 and familial history [1]. Genetic Risk Factors Familial susceptibility of…

While the cause has remained somewhat of an enigma, persistent stuttering exhibits distinct behavioral, neural and genetic characteristics. Throughout many years, a variety of treatments have attempted to ameliorate overt stuttering behaviors; however, most therapeutic options provide unstable, effortful, and/or unnatural sounding results with high relapse rates. Recent research suggests second speech signals provide natural sounding speech coupled with stable and effortless reductions in overt…

According to the DSM-V (2013), Attention-deficit/Hyperactivity Disorder (ADHD) is defined as a persistent pattern of inattention and/or hyperactivity-impulsivity that interferes with functioning or development (DSM-V) for at least six months. ADHD has two sub-types that can present independently or combined. Inattention manifests in behavioral symptoms like difficulty sustaining attention in tasks and play activities, failure to give close attention to details or make careless mistakes,…

Ms. M is a 27-year-old women who recently moved from her hometown Minneapolis, Minnesota to Salt Lake City, Utah for a job offer. She lives alone and works as an English teacher at the East High School in Salt Lake City since the beginning of the school year after her graduation last summer. Since it is the first time she has her own classes, it is sometimes quite stressful for her even if she likes her job. The past few years, she reported numerous neurological complaints which came and went…

could alter a person’s decision to begin partaking in such activities. The limbic system is a neural system that includes the hippocampus, amygdala, and hypothalamus. This system, associated with emotions and drive, is located below the cerebral hemispheres and holds a very valuable part of the brain. The hippocampus has the important role of processing explicit memories for storage. Losing this part of the brain is being depleted of the ability to form new memories, which significantly…

evaluation was conducted for the purpose of identifying and clarifying diagnoses and establishing treatment recommendations. Comprehensive neuropsychological assessment of Joseph Henry reveals a pattern of dysfunction associated with a right cerebral hemisphere locus, as well as evidence of frontoparietal networks and subcortical dysfunctions. The pattern is consistent with both predisopsed non-verbal difficulties as well as difficulties associated with diffused axional injury, commonly…

"I now have absolute proof that smoking even one marijuana cigarette is equal in brain damage to being on Bikini Island during an H-bomb blast.” -- Ronald Reagan. There has been so many different types of research on this specific plant about the positive and negative possibilities it can have on our world. Many people argue about how it can benefit for medical studies. Marijuana. Weed. Pot. Whatever you want to name it, it 's one of the most popular illegal substances in the world,…

70% of all gliomas(2). The concept of brain function organization into well defined and localized areas is the legacy of pioneering studies of the 19th and 20th centuries. In 1909 German neurophysiologist Brodmann published ?Localisation in the Cerebral cortex? where he subdivided the function of the brains and numbered the areas from 1 to 47(3). Six areas can be identified as eloquent…

Glioblastoma multiforme (GBM) is a type of malignant brain tumor typically found in the cerebral hemispheres, but can be found anywhere in the brain or spinal cord. These tumors are highly malignant meaning a large number of cells reproduce at any given time. There are two main types: primary, or de novo meaning the tumors make themselves known quickly and are extremely aggressive, and secondary meaning the tumors have a slower growth history but are equally aggressive . Secondary tumors are…
