Cerebral cortex

Disease Alzheimer’s disease is not a new disease. “Alzheimer’s” was first described by German psychiatrist and neuropathologist Alois Alzheimer in 1906. Alzheimer’s disease is an irreversible, progressive disorder involving neural degeneration in the cortex that slowly destroys the memory and thinking skills, and eventually the ability to carry out activities of daily living (Karch, 2013). In most people with Alzheimer’s, symptoms first appear in their mid-60, and accounts for 60% to 80% of…

womb… instead an in utero fetus with the potential of becoming a child.” (Planning Parenthood) The fetus creates no genuine brain wave activity until the third trimester of the pregnancy, only instinctual electric impulses prior to that. Its cerebral cortex does not appear till the second trimester, thus meaning it can feel no pain in its first 12 weeks of…

degeneration diseases do, such as Alzheimer's and Huntington's. Some affected of the disease may act uncharacteristically aggressive due to themselves being frightened, humiliated, and or frustrated. The disease rapidly causes degeneration of the cerebral cortex or higher thinking portion of the brain therefore, like with Alzheimer’s, judgement and self-control will likely be affected. Good behavior and manners learned during childhood may be completely forgotten. Those affected may worry that…

highways the brain uses to process information (Willis, 2010). Subsequently there is also an increase of potassium released into the brain tissue, which requires to body to use more energy to establish a balance; during which, there is a slowing of cerebral blood flow, and the brain must increase the amount of effort being used to complete the same level of work (Giva & Hovda, 2001). Additionally, there is a decrease of adenosine triphosphate (ATP) after a brain injury, but at the same time,…

at the midline of the body as normal, widen out during the swing phase, and then return to the midline for heel strike. This type of gait pattern is common among cerebrovascular accident (CVA) patients or any form of head injury causing motor cortex or cerebral damage. With a CVA patient, their foot is set in plantar flexion and possibly dragging the floor which forces them to swing their leg out during ambulation. With an abducted gait the patient’s…

receptors are excited by any type of tissue damage. 3. Referred pain is a phenomenon when you feel pain in an area other than where the pain originates from. 4. The thalamus and cerebral cortex are the parts on the brain that interpret pain impulses. The thalamus establishes the awareness of pain, and the cerebral cortex verifies the severity of the pain, discovers where the pain is coming from, and responds to the pain. Five Special Senses 1. Sense of Smell The olfactory organs of the nose…

Language is how we communicate today. But there are several ways to communicate with others besides talking. There are people that are blind, deaf, or people who have speech impediments. All of these types of people have their own way of expressing and receiving a message. There are ways to learn these skills on language, and the body has reacts in certain ways when you are trying to receive the message and give the message. These skills can affect learning abilities. But we all have a…

Psychology my junior year, I came across intriguing optical illusions that reveal the inner workings of the brain to surprising experiments that exposed the latent intentions of people. The brain is remarkably complex and astounding—from the folds of the cerebral…

main parts of the brain, the forebrain , midbrain , and hindbrain . the forebrain consists of the cerebrum , which is the largest part of the human brain , also collaborated with higher brain functions such as thought , and emotion . The cerebrum cortex is broken up into 4 parts. Those 4 parts are the frontal lobe , parietal lobe , occipital lobe and temporal lobe. The frontal lobe (6) is associated with planning , reasoning , parts of speech , movement , emotions , and problem solving. The…

it can also be seen in 1-10% of people in there 30’s. Alzheimer’s is considered to be a progressive, degenerative disorder of the cerebral cortex. It is known to interfere with cognitive and behavioral impairment that causes social and occupational functioning. The cortical degeneration is marked in the frontal lobes, but the atrophy occurs in all areas of the cortex. The cause of Alzheimer’s is still unknown, but there is factor’s that contribute to this disease, such as neurochemical factors,…
