There are three major brain divisions. They are the cerebrum‚ the brainstem‚ and the cerebellum. The cerebrum contains 40% of the weight of the brain and is founded in the superior part of the brain. This portion of the brain has many functions and lobes which perform certain functions. The frontal lobe is involved with “activating and controlling both fine and complex motor activities.” This involves speech. It is also involved with the executive functions‚ such as reasoning and rationalizing‚ among

Memory Loss Due to Brain Trauma Numerous psychological studies have been done over the subject of the effects of accidental head trauma leading to various memory problems such as memory loss. These studies ranging from the very mild to the extremely severe brain traumas cases and has various effects on memory whether it is short term of long term memory problems and loss. This paper is going to more specifically cover vehicular accidents that involved head trauma leading to memory loss and other

Article St. Anne-Mayo astrocytoma grading system Dr Jeremy Jones and Dr Frank Gaillard et al. The St Anne-Mayo grading system (also known as the Dumas-Duport grading sustem) introduced in 1988 is one of the more popular systems for grading diffuse astrocytomas 1-3. It is a 4 tiered system (like the WHO grading system) and uses the presence of 4 morphologic criteria to assign a grade: 1. nuclear atypia 2. mitosis 3. endothelial proliferation-’piled-up’ endothelial cells.

Baker’s Cyst Anatomy And Physiology To better understand a Baker’s cyst‚ it helps to understand the anatomy of the knee joint. A cyst is a lined sac that contains fluid. Cysts that form around joints are due to a bulging of the joint capsule. A Baker’s cyst develops from the knee joint capsule. It protrudes into the tissues in the back of the knee. Four bones come together at the knee joint: * Patella/Kneecap - The patella is a small‚ flat‚ round bone that articulates with the femur in

Discuss the implications of the of the split-brain procedure (severing of the corpus callosum) for the understanding of the connections between the left and right hemisphere. The first known split-brain surgical procedure performed on humans’ was in the early 1940’s by Van Wagenen and Herren‚ in which both intended to control seizures of patients who suffered intractable epilepsy (Francois Boller‚ Jordan Graffman‚ 2000). The procedure performed by Van Wagenen and Herren was based on the speculation

Physical changes have a bigger impact on the brain than chemical changes. Some injuries to change the brain include concussions‚ tumors‚ assault‚ lobotomies‚ and accidents. A concussion is a temporary unconsciousness caused by a blow to the head. The term is also used loosely of the aftereffects such as confusion‚ dizziness‚ and lightheadedness. Concussions can usually be caused by sports or any other accidents to the head. A specific part of a brain could be either damaged or bruised. A violent

Split-Brain Patients: The independent functioning of the left and right hemisphere when no longer connected by the corpus callosum. The human brain is a dynamic and elastic processing unit that manages the great extent of human life. This entails both conscious and unconscious functioning of each human system. For example‚ the brain controls emotions through behaviors‚ physiological responses (both autonomic and hormonal)‚ and feelings in response to stimuli from the environment (Carlson

Amberlee Hoagland 12.20.2012 COLL100 Diane Roberts The human brain is a miracoulus organ.It is the main sorce where we get our creativie and logical thinking from. Many scientists and people agree in the left and right brain theory that our right and left hemispheres of our brain have two separate sides that do different types of thinking.Left being logic or critical thinking and the right being more creative and intuitive. They also believe
