Cerebral hemisphere

also can be temporary; it can be resolve in days or weeks. Ataxic Dysarthria located in the cerebellum. It generally results from bilateral; or generalized damage to the cerebellum; focal lesions typically affect area of superior peduncle, lateral hemisphere or paravermal regions. Friedreinch ataxia, Olivopontocerebellar atrophy, strokes, traumatic brain injury, tumors, toxic conditions, metabolic conditions and neurotoxic levels of several drugs can cause ataxic dysarthria. The characteristics…

The brain is divided into two broadly different structures: those comprising the cerebral cortex and those comprising the sub-cortex. Which structure is conventionally seen as responsible for thought, conscious awareness, voluntary actions, and so-called higher mental processes? Cerebrum??? 4. In a drawing of the side of the brain…

Cannabis, or cannabis sativa, originated in Central Asia and has been used for its psychoactive properties for many years (Iversen, 2008, p. 6). It affects the brain of adolescents and adults differently through the binding of CB1 receptors due to distinctions in neurocognitive development. There are certain changes in gray and white matter densities, brain volume, as well as endocannabinoid concentrations. This creates aberrations in cognition and memory performance. Cannabinoid’s structures…

Young children are most vulnerable to brain development and enhancement from their time during preschool to puberty; scientists and neurologists studied them closely as they grew, stating that children are a significant window of opportunity for music learning. During their preschool and primary ages, young children imply their positive attitude toward music, often experiencing with different sounds and tones. Frances Rauscher and her team of scientists conducted a study in which they observed…

There are many pediatric impairments and disorders that are treatable within a physical therapist’s scope of practice, such as Cerebral Palsy or Down syndrome. However, what happens when a child is being treated, who also has a diagnosis that cannot be treated with physical therapy, like Attention Deficit Hyperactive Disorder? It is our job to research the diagnosis and learn as much as we can, in order to give the best possible care to the patient. Knowing about the pathophysiology, signs and…

Importance of studying cancer Cancer is a vastly complex disease exhibiting a plethora of genomic alterations and resulting regulatory failures at the root of its progression. Following the milestone of the Human Genome Project (HGP) era, researchers are now focusing on integrating the rich genome-wide association studies (GWAS), single-nucleotide polymorphism (SNP) data, and identified gene signatures within the in vitro, in vivo and clinical frameworks to further our understanding of the…

If you were to think of a horse today, you would say they are big, strong mammals. 55 mya, horses did not look like this. With the mannerisms of a deer and the traits of a dog, the first known horse darted through forests in North America during the Eocene Period. As time went by, many horses evolved like the Orohippus, Epihippus, Mesohippus, Miohippus, Parahippus, Merychippus, Pliohippus, Dinohippus, and finally the Equus. In Greek, ‘hippus’ means horse. Fossils of the first known horse were…

Glioblastoma multiforme are tumors that affect glial cells, specifically the oligodendrocytes and astrocytes that aid in the health of the neurons located in the brain. Generally, in most adults, glioblastoma multiforme (GBM) generates in the cerebral hemispheres, especially the temporal and frontal lobe of the brain. Typically, GMS’s emerge in the brain as “de novo”, or newly formed, and transform into lower-grade astrocytomas, or oligodendrogliomas (Rothmans, n.d.). Affecting the nourishing…

Working memory is the restricted capability of the brain to store, maintain, manipulate, and process information (Rudner, et. al, 2009). This paper investigates the current research on working memory and the effects of sign language on it. Sign language is used primarily by those who are deaf and are unable to communicate through speech. It is the use of hand signals and motions to produce language. There are many different forms of sign language that are widely used and accepted, among them…

Are 16 and 17 year olds capable of making medical decisions? From birth to adolescence, parents entrust their kids with responsibilities and decision making. At what age do people have the right to determine whether or not they receive medical treatment. 16 and 17 year can become Veterans but still has to have consent from a guardian to receive medical treatment. More and more juveniles are being tried as adults, but they’re not be allowed to make their own medical decisions. What are the…
