One Brain or Two May 15‚ 2013 In the 1960s Roger Sperry and Michael Gazzaniga conducted human neurological studies in California to determine a better understanding regarding the communication of the brain’s hemispheres. Through their research we have learned many things about human brain function. The experiment involved removing the cause of epilepsy in severely affected individuals by severing the corpus callosum nerve fibers thereby separating left hemisphere from right. Many of the daily motions

The author involves statements in his claim to back up his answer‚ he involves statements like how sixteen-years-olds are different medical wise but they are still immature criminal wise meaning they can get off the hook easier. “This is why 16-year-olds are just as competent as adults when

to the American Brain Tumor association Glioblastoma has been described as “tumors that arise from astrocytes—the star-shaped cells that make up the “glue-like‚” or supportive tissue of the brain. These tumors are usually highly malignant (cancerous) because the cells reproduce quickly and they are supported by a large network of blood vessels.” In addition‚ this form of cancer attacks surrounding tissue which prohibits the ability to spread across the body irregularly. GBM tumors are generally found

Radiation therapy (RT) is an essential component in the interdisciplinary treatment of brain tumors. Independently of histology‚ radiation plays a central role and has shown to increase local tumor control. Developments in radiation oncology are always aiming at an increase precision of dose delivery: More conformal coverage of target volumes‚ steep dose gradients to surrounding tissues‚ and sparing of organs at risk (OAR). In photon therapy‚ based on 3D-RT‚ stereotactic radiotherapy was a big step

CARDIAC TUMORS INTRODUCTION Cardiac tumours occur quite rarely‚ with metastatic neoplasms three times more prevalent than primary tumours. A large variety of benign and malignant tumours of the heart have been described. These tumors are found mainly in the heart‚ but can occur in the pericardium or the great arteries. Secondary cardiac involvement from malignant tumors of adjacent organs (lung‚ thymus) or from kidney (Wilms tumor) or liver‚ or even remote organs‚ are also seen. ANATOMY AND PHYSIOLOGY

of PRL receptors has been identified in different brain regions‚ such as choroid plexus‚ olfactory bulb‚ and hypothalamus [54]. Since 1980s‚ studies have suggested the relationship between PRL and CNS tumors. Ciccarelli et al reported in 2001 that high PRL levels and increased PRL receptors were found in some of the patients with meningiomas and schwannoms‚ indicating that PRL might be involved in the growth of the two benign intracranial tumors [9]. The later study by Leães et al in 2007 showed

Brain Disorders One out of five Americans struggle with a brain disorder. The brain is a fragile muscle which controls thoughts‚ memory‚ speech‚ and movement. Any form of distress to the brain can cause loss of functions we take for granted. Disorders can affect you physically or mentally. Mental disorders can affect your mood which results in depression‚ anxiety disorders‚ schizophrenia‚ eating disorders and addictions; physical disorders affect your daily tasks. Brain disorders are caused by genetics

Malignant astrocytomas or Gliomas are the most frequent form of primary cancer that arise in the brain. The most malignant and aggressive type of glioma is glioblastoma multiforme(GBM). GBM ‚which called grade IV astrocytoma‚ is one of the most common and deadly primary malignant brain tumor in adults with a high degree of morbidity and mortality and accounts for about 15% of all intracranial tumors in adults ages 40–75(2‚ 3) Incidence rates of glioma in The United States yearly is about 5 in 100

All people do not deal with traumatic brain injuries the same in the way that it takes people a different amount of time to recover than others and that it effects the patient’s qualities that they had prior to the injury differently. Traumatic brain injuries are common and they disable 150 million- 200 million people per year which is the leading cause of disability in people under 40 years old by injuring the frontal and temporal lobes. Recovery times are different for different people (most people

Concussions The brain is a very delicate and complex organ . It is located inside the head and controls everything we do from movement ‚ our five senses ‚ emotions ‚ thoughts ‚ memory ‚ breathing ‚ our heartbeat ‚ digesting food and our speech . The brain is made of a gelatin like substance and is protected by cerebrospinal fluid and the skull . So imagine what would happen to our brain if it would get damaged . Anything that our brain controls could be altered either temporarily or
