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 of the…

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…

things we humans have. The human brain has four parts: Hindbrain, Midbrain, Forebrain, and Cerebral Cortex. With each part comes its functions. For hindbrain the parts are medulla, cerebellum, and pons. For forebrain the functions are the limbic system, thalamus, hypothalamus, basal ganglia, and cerebral cortex. And last the cerebral cortex, the sections are occipital lobe, temporal lobe, parietal lobe, and frontal lobe. The hindbrain is located at the rear of the skull. Hindbrain has…

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…

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…

that increase the risk of adverse side effects of alcohol on one. In other words, main areas in the brain are under construction and are more sensitive to the toxic effects of alcohol. These effects inhibit parts of the brain such as the cerebral cortex, central nervous stem, frontal lobes, hippocampus, cerebellum, hypothalamus, and medulla. In more detail, it makes one…

The definition of power is: ‘the ability to direct or influence the behavior of others the course of events’. In the novella of ‘Mice and Men’ power is very complex however it can be broken down into four main parts. Physical power, power of seduction, power of hierarchy and power of dreams. Each character symbolist a different aspect of power such as Lennie has physical power however he doesn’t have mental power that George has but George don’t have power of hierarchy as Curley has.…
