than the lower scoring group (Blair, 2003 Jan.). The more disruption to the neural systems, in this case for emotions, the more it increases "antisocial tendencies" (Raine and Yang, 2006). Researchers also think that the orbitofrontal cortex and dorsolateral prefrontal areas also have a part to play in abnormalities in APD individuals. Some believe that those areas have lesions which results in impulsiveness and not exactly concerned with the consequences of their actions. Two MRI's also…

important that correlations between volume of the brain and intelligence in populations of children are lower in comparison with populations of adults. Lower correlation in the population of children explains by the incomplete maturation of the cerebral cortex that occurring in different brain structures at different…

weeks. Participants’ brain activity was examined both before and after the trials during which they were exposed to the cues related to the game. The authors found that there was increased brain activity in the anterior cingulate and orbitofrontal cortex in the group with excessive Internet gaming behaviors after six weeks of the playing the games, but not in the control group when exposed to the game cues. These findings are important and suggest that the brain activity of those with Internet…

one peer reviewed, that share the same story in completely different ways. “How Walking in Nature Changes the Brain” is an article in the New York Times written by Gretchen Reynolds, and “Nature experience reduces rumination and subgenual prefrontal cortex activation” a peer reviewed article by Gregory Bratman, J. Paul Hamilton, Kevin S. Hahn, Gretchen Daily, and James Gross. Both describe that city life can be making people depressed, while in nature the brain is stimulated by positive means…

brain, the prefrontal cortex, is rapidly changing during the physical growth of a teen. The prefrontal cortex is responsible for cognitive development which has been examined through MRI images and other studies. Tasks like “decision-making, planning, planning what you 're going to do tomorrow or next week or next year, inhibiting inappropriate behavior, so stopping yourself saying something really rude or doing something really stupid”(Blakemore,2012) are controlled by the prefrontal cortex.…

those with mild anxiety showed increased D2 values in the left prefrontal regions. According to Muzur, Pace-Schott, & Hobson (2002) the transition from waking to NREM is characterized by deactivation in the frontal cerebral cortex. This deactivation increases with the deepening of NREM sleep and stays the same during the transition from NREM to REM. However, during the onset of REM portions of the ventromedial, limbic-related prefrontal cortex and closely associated medial subcortex are…

This can be linked to the Interactions of the Sociomotional system that is located in the limbic system, including the amygdala and prefrontal area, and the cognitive control system located in the prefrontal and parental regions (Steinberg, 2010A, 2010b). Risk taking in adolescence can involve substance abuse, binge drinking, and impaired driving. Risk taking can be major factors that lead to delinquent, antisocial, and…

responsible for the “flight to fight” situation. Other parts, like the sensory cortex, is also involved in receiving or sending off data to and from the brain.Upon my research, there were many important information being taken to consider the fact that if phobias do affect a person. Though, I learned that the amygdala is responsible for sending data to two routes of the brain, the thalamus and the medial prefrontal cortex(“The Amygdala: The Body’s Alarm Clock System”). The first route is…

Video Games and How They Affect our Biology In the past, there have been many debates on video games and whether or not the effects they can have are beneficial or harmful. Most people would tell you that it is the latter; however, newer research and studies suggest that video games present many more advantages than what one would expect. They have been proven to be of use in aiding those with mental disabilities as well as providing an alternative means of exploration for people with physical…

The current literature suggests that Mindfulness-Based Stress Reduction (MBSR) regulates the areas of the brain implicated on self-regulation and self-directed attention and behavior1. The activation of such areas of the brain contributes reducing stress during the emotion regulation, improving anxiety and mood symptoms in Depression and Anxiety Disorders2. A key aspect in these disorders is the rumination and the focus on the future and the personal worries, keeping the person away from the…
