Exploratory Synthesis
Degeneration within the hippocampus has been shown to occur as humans get older. This area of the brain is important for learning and memory and as individuals age, there is a significant decrease in hippocampal size. Physical activity has been studied as a way to lessen this decline in hippocampal volume with the intention of brain neurogenesis and neuroplasticity. A non-sedentary lifestyle, specifically aerobic exercise has been associated with a greater amount of cells and greater hippocampal volume. This exploratory review will discuss findings from research, primarily using humans, rats or mice as subjects, showing the specific areas of the brain that physical exercise effects as well as the benefits it has on certain brain regions.

    Summary Of Can You Build A Better Brain By Sharon Begley

    In the article, “Can You Build a Better Brain,” the author, Sharon Begley, introduces some scientific research about enhancing brain’s performance and discusses how we can improve our brain through training. The author begins the article by emphasizing that brain is more complicated than muscle and scientists still do not completely understand the mechanisms of cognition; furthermore, many studies about brain enhancement do not actually show the mechanisms of brain and how doing a certain activity can help improving it. The author continues the article by talking about the studies claiming that certain vitamins and food can improve cognitive function; however, Begley points out that these studies still contain many problems that weren’t mentioned…

    Hippocampus Research Paper

    It can also function as a memory “gateway” where new memories pass before entering permanent storage in the brain. Hippocampal damage can result in anterograde amnesia which is loss of the ability to form new memories, although the old memories are safe from loss. So someone who has an injury to the hippocampus may have good memories of there childhood and the years before the injury, but almost no memory of anything that has happened since. Some memories, like the memory for a new skill or habit, can sometimes be formed even without the hippocampus. A current research project is to determine exactly what kinds of learning and memory can survive hippocampal damage, and how these kinds of learning can be used to guide rehabilitation. The hippocampus is very sensitive to reductions in oxygen level in the body. So periods of oxygen deprivation which are not fatal may nonetheless result in damage to the hippocampus. This could happen during a heart attack, respiratory failure, sleep apnea, carbon monoxide poisoning, and near-drowning. Hippocampus is also a common focus in epilepsy, and can be damaged through chronic seizures. It also is sometimes damaged in diseases like herpes encephalitis, and is one of the first brain areas to show damage in Alzheimer’s disease…

    Source One Synthesis Essay

    The topic of Source One is how explorers and colonists of the New World took part in horrific, illegal events to colonize the foreign lands, but yet they were not the ones who suffered from these events. This phenomenon is portrayed in the source through the image of a wanted poster for Christopher Columbus, where Columbus is wanted for several offences including: genocide, racism, initiating the destruction of a culture and rape. The poster also goes on to state that the reward for Columbus is “500 years of tourism”. The reward symbolizes how despite the atrocities that the explorers and colonizers took part in, they would be remembered throughout history for their accomplishments and not the horrendous events that brought them to those successes. The illustrator’s perspective on the source is the idea that colonizers of the New World were…

    Being physically active is the most beneficial thing for the human body, physically and mentally. Exercise decreases the risks of heart disease, diabetes, and stroke. It treats and prevents depression, increases muscle strength and cognitive function, and prevents obesity. It’s estimated that only 20% of the people in America get enough exercise, with an obesity rate of over 25% and an overweight rate of over 35%. Depression is a worldwide disorder that affects over 117 million people. Although it can lead to other disease and is one of the primary disabilities, it is treatable. The primary treatments include medication and therapy however exercise can treat and prevent depression just as well as medication in a lot of cases (Behrman, 2014). Heart disease is the number one cause of death in Americans. 1out of 4 deaths in America is the result of heart disease. The two main causes of heart disease are high cholesterol and blood pressure and are typically treated with statins and ACE inhibitors, however with proper exercise both of these issues can be controlled just as well and without side effects. As people grow older in age they can have a decline in cognitive ability, resulting in dementia such as Alzheimer’s. Staying active and exercising regularly keeps the brain healthy and elastic, preventing breakdown. Evidence suggests that regular exercise is more beneficial to our general health than taking medication because it decreases the risk of heart disease, decreases depression, increases cognitive function and has no chemical side effects.…

    The focus of this article is the bias found in evolutionary and endocrinological studies. These studies serve the purpose of defining and tracing human nature through evolution and present times. Evolutionary studies address the description of human descent from primates. These studies seek to outline the sequence of changes and mechanisms of action that make up the evolution of humans from primates. The general theory of evolution is used to reconstruct history with facts and evidence from fossils and other remains. Endocrinology is the study of how hormones affect human anatomy and physiology, behavior, and cognition.…

    Sojourner Truth in her speech, "Ain't I a Woman?" demonstrates that she's tired of inequality and fights for women's rights by having comebacks to the white men that don't think negro women like herself should have rights. In Malala Yousafika's interview, she views education as a gift and feels girl should also have the right to go to school. Both of these women feel women are as capable as men. Sojourner and Malala both express defiance against the law, show persistence for what they are fighting for, and fought morally for women's rights.…

    The people of America live in a country whose citizens are gifted with the system of Democracy where each person has their voice represented in decisions of the nation. The inherent responsibility of each voting age citizen of America is to research the positions and views of all candidates that represent them and then punch, mark, or press the space next to the candidate that they believe would best represent him or her. But not all Americans would care to look closely at the opinions of the election candidates especially in a race as highly publicized as the modern presidential elections.…

    Exercise Benefits

    Is my phone over there? Such questions of confusion or thoughtlessness seem to be common in an aging adult’s life. Simple tasks become difficult to complete yet even remember. What’s the answer to creating a better memory? Of course, the answer is exercise. Considering that adults over 50 report staying mentally strong as a top concern, exercise is a very simple, inexpensive fix. Exercise can boost the size of the hippocampus while also increasing the blood flow to this region which is the key region affected by Alzheimer’s. The increase of blood flow produced by exercise also affects the anterior cingulate (relative to emotional tasks and linked to superior cognition in later life) which indicates a higher neuronal activity and metabolic rate. These factors contribute to quicker firing neurons as well as a greater capacity for memory retention. Studies have even proven that the parts of the brain responsible for critical thinking and memory, the prefrontal cortex and the medial temporal cortex, are shown to be enlarged in those with active lifestyles (Godman). The chief director of the Center for BrainHealth, chair at Dee Wyly Distinguished University, and researcher of physical and emotional health states that “physical exercise may be one of the most beneficial and cost-effective therapies widely available to everyone to elevate memory performance”. One study using 86 woman age 70-80 with “subjective memory complaints” were divided into…
