Huntington’s Disease Huntington’s disease is one of the most dreaded diseases among the group of genetic diseases. Huntington’s affects the basal ganglia portion of the brain it is reasonable for a person’s motor functions. Over time huntingtin’s destroys this area. The disease’s name is derived from the ancient Greek word dance. It is named this because after the portion of the brain is partially destroyed, the person walks with an unintentional sway, an almost dance like movement. (Blachford)…

“Genes make a difference. Even if we were all raised in the same intellectually stimulating environment, we would have differing aptitudes. But life experiences also matter” This is a quote from the textbook Psychology by David Myers and Nathan Dewall. Intelligence is something complex and difficult to understand where it originates or how much a person can get of it. Our intelligence is based on our ability to learn and capability to understand our surroundings. Many people think how smart we…

The Stroop effect is a demonstration of interference in the reaction time of a task. It is the finding that naming the color of the first set of words is easier and quicker than the second. When the name of a color (e.g., "blue", "green", or "red") is printed in a color not denoted by the name, (such as the word "red" printed in blue ink instead of red ink), naming the color of the word takes longer and is more prone to errors than when the color of the ink matches the name of the color. In his…

1. Neurogenesis and memory 1.1. Neurogenesis in the hippocampus The hippocampus is a brain region that responsible for learning, memory and mood. One of the important reasons for memory and mood dysfunction is the dentate gyrus (DG) reduction [12, 13]. The subventricular zone (SVZ) and the subgranular zone (SGZ) of neural progenitor cells generated neurons and glia in adulthood and during adulthood [14]. Neurogenesis also have a role in mood regulation; the dorsal hippocampus is an…

Even though there are other structures in the brain that were selected for greater growth and complexity, it is noted that evolution has impacted the change in the cerebral cortex physiology and morphology and in consequence has influenced intelligence the most(Cherniak 2012). Now that it is understood what evolved, looking at what led to the evolution is just as important. Scientist theorize that the evolution…

Imagine a world without music. There would be no such thing as rhythm, tempo, harmony, pitch, and many other elements that make up one of the most cherished ideas on Earth. Proms and homecoming dances would not be the jumpy, yet romantic, nights that couples dream of. The people would be missing an irreplaceable piece of the heart. While music is an important part of the heart and the soul, some have the audacity to say that music is a distraction. While it may be getting in the way of doing…

The structure of the brain is constantly changing from birth throughout the lifetime. It states that as our brain ages we start to lose our memory, retrieve new information etc. Also, people usually who are above age sixty an experience in cognitive decline, for example: weaken memory loss, decision making, social skills, remembering, paying attention, problem solving, and unclear thoughts. The experience of cognitive and memory loss as aging affects our daily routine and can impact out…

Funtional organization is defined as the principle of specialization based on function or role. So, when discussing functional organization it is my understanding that this concept refers to the idea that regions communicate based on a larger goal (the brain works together in ways that make sense in coordination with the person’s actions and thought processes).The functional organization of the brain is best categorized as a flexible, but constrained network of interrelated regions. That being…

cortex, bilateral activation in the intraparietal cortex and right superior parietal lobe. However, posterior parts of the superior temporal sulcus were also activated in the left hemisphere and it should be noted that the bilateral activations in the premotor and intraparietal cortex were larger in the left hemispheres than in the right. Individuals experienced greater activation levels in these classical mirror regions of the brain while observing the style of dance in which they had training.…

I Dan Seigel’s lecture on the mind, behavior, and the climate fascinating. I have been reading his Seigel’s book Parenting from the Inside Out for my practicum, and it was interesting to hear the insights from his lecture. Seigel starts out his lecture by drawing a triangle on a poster board. On the bottom left corner he writes the word “mind,” on the bottom right corner he writes the word “brain,” and on the top of the triangle he writes “relationships.” He explains that the brain is a…
