Cerebral hemisphere

Simon LeVay a neuroscientist that studied various parts of the brain along with the differences in the sizes of the different hemispheres of homosexual/heterosexual men and women. Dr. LeVay explained the theory that the INAH 3 found on the hypothalamus is somewhat different in homosexual men and women when compared to heterosexual men and women. He states that INAH 3 is typically…

it leads to activity in the brain which then creates growth. Cross-patterning movements such as swimming activate both cerebral hemispheres and all four lobes of the brain simultaneously, which can result in heightened cognition and increased ease of learning (“Swim Kids”). Immersing the body in water to the level of the heart increases blood flow through the brain's cerebral arteries, thus improving vascular health, blood circulation, and cognitive function. Nine healthy males participated in a…

The brain is the most complex part of the human body. It is also the most powerful organ of the human body, although it only weighs approximately three pounds (Alzheimer’s Association, 2012). The brain is responsible for all thought and movement that your body produces. The complexity of the brain allows humans to interact with their environment and communicate successfully with others. The brain is not just one huge organ, it has numerous small divisions that enable humans to thrive and survive…

Lateralized Cortical Connections, their hypothesis was that the reflexive attention in response to gaze direction correlates with the hemisphere specialized for processing faces. The people used in this experiment are one male and one female. They are both 44 years old and suffered from intractable epilepsy. Both subjects, J.W. and V.J., had their cerebral hemispheres disconnected because of their epilepsy. J.W. is a right handed male with…

The patient presents an intracranial lesion to the anterior frontal lobe. This will result in damage of the prefrontal cortex causing apraxia and mild rigidity. The prefrontal cortex contains Brodmann’s Areas 9, 10, and 11. Damage to Area 9 is “frontal syndrome” which means the patient rarely follows a plan to completion. Area 10 is involved in judgement, anticipation of consequences, and social intelligence. Area 11 is on the ventral surface of the frontal lobe and incorporates emotions,…

2.1 Result of a Cerebrovascular Accident (CVA) of the middle cerebral artery which supplies Brodmann areas 312 and 4 in the left cerebral hemisphere A cerebrovascular accident is also known as a stroke. It is when the blood which flows to the brain is cut off, by a blocked or ruptured artery that goes to the brain, causing the brain not to receive enough oxygen and cells of the brain then die11. ?????? result of CVA on middle cerebral artery 3.2.2 Difference between a haemorrhagic and an…

There are a variety of similarities in the content in both the Broderick and Blewitt text and the reading by Sylwester. Broderick and Blewitt open the chapter by explaining the intricate process of how the brain is formed and how it develops throughout gestation. Once the brain structure itself has formed in the womb, nerve cells called neurons begin to form (Broderick & Blewitt, 2010). The brain sends information to the rest of the body through neurotransmitters that are housed in terminals…

The cerebral cortex is defined by Kalat (2014) as being the most prominent part of the forebrain, consisting of multiple layers of cells that are located on the exterior of the cerebral hemisphere. These layers of cells consist of either white matter or gray matter, as well as the axons that transfer information with neurons, either through the corpus callosum or the anterior commissure, and connect both the right and left hemispheres of the brain (Kalat, 2013). The cerebral cortex contains six…

specific directions to a destinations as well as road regulations. Furthermore, the angular gyrus can help drivers make approximate calculations on the road such as how long the distance of their trip may be from point A to point B. 21. Cerebral Cortex: The cerebral cortex is a trench like layer of gray matter in the cerebrum. This section of the brain is used for high brain functions, voluntary movement, the coordination of sensory information, learning and memory, and the expression of…

“Stroke is the most common cause of AOS.” (Duffy, 2013). As mentioned by Duffy, apraxia of speech is almost always identified because of the cause being a stroke in the left cerebral hemisphere. There are some uncontrollable factors of stroke that should be considered in Carol’s case as stated by National Stroke Association such as age and gender. The risk for a stroke increases with age. “After the age of 55, stroke risk doubles for…
