Abstract Attention Deficit Hyperactivity Disorder known as ADHD is a prominent behavioral disorder defined as ongoing and increased levels of inattention hyperactivity and/or impulsivity. The primary goal of this paper is to review the current research. This review will be exhaustive in nature and consist of a description with a focus on sex and age differences, the neural pathology focusing on the abnormal brain structure and function of ADHD patients, etiology with a focus on genetic and…

emotional or physical impulse, in this case entertainment. The positive association of dopamine often triggers the urge to repeat a stimulating activity. As the stimulant is repeated the excess dopamine production then takes over the cingulate gyrus and the prefrontal cortex, the areas controlling motivation and judgement, in the brain. Richard Freed, author for the Huffington Post, summarises this statement, “The ‘hijacking’ of excess dopamine removes the brain’s drive to complete other…

Introduction Page This research paper explores what exactly Obsessive Compulsive Disorder is. This topic was chosen because of the lack of knowledge and misconception on OCD to the public eye. Many people think this is a disorder of excessive cleaning, but that is incorrect. Obsessive Compulsive Disorder is a complex disorder with three main parts to understand it: symptoms of OCD, treatments of OCD, and what causes OCD. These findings that we will discuss are significant because of what was…

phenomenon known as attentional blink. Some experienced action-game players, however, barely blink, catching every target digit as it passes by. Brain scans provide more evidence of the benefits of action games. Widely dispersed regions of the cerebral cortex regulating attention change their activity more in action-game players than in…

This paper will focus on a movie called “Shaun of the Dead.” Shaun and his girlfriend Liz are important characters in the movie. Although his girlfriend’s view him as the sluggish man who spent time playing video games with his best friend “ED” and spending an enormous amount of time in a traditional London pub, he was still able to save his girlfriend from dangerous creations “zombies.” Also, Shaun portrays as a person who forget vital events and always late for important events. In addition,…

There has been recent research that has stated that obsession-compulsion disorder involves the dysfunction in a neuronal loop that runs from the orbital frontal cortex to the cingulate gyrus, striatum (cuadate nucleus and putamen), globus pallidus, thalamus and then back to the frontal cortex (Yerevanian, 2010). To back up The Carlat Psychiatry Report’s research, supporting the hypothesis is the results of neurosurgical treatment of obsession-compulsion disorder (Huey, 2010). Believed to…

might be able to circumvent some of the problems normally associated with multitasking by training their brain to do so. The article “Training Improves Multitasking Performance by Increasing the Speed of Information Processing in Human Prefrontal Cortex” provides a large amount of evidence stating that this is in fact true. In addition, it is possible that in some situations, multitasking can provide more benefits than downfalls. Another issue branching out from these is that of learning in…

I have always been fascinated by the operations of the human brain, which is why I decided to study Psychology. When I was living in South Africa my major was law, and my minor was Criminology. Having this background and being able to see the difference in America has truly expanded my interest how the mind of a serial killer works. Who would ever guess that the baby born mere seconds ago would grow up to become a serial killer? Did Jeffrey Dahmer’s parents know that he would grow up to cut…

Hallucinogens are a chemical substance that causes hallucinations. Hallucinations, derived from Latin, álucinari, means to ‘wander in the mind.’ Hallucinations includes all sensory perceptions whether real or not. Psychedelics, Greek derived, translates to ‘soul and mind manifesting’ and are a class of hallucinogens that are useful tools in gaining understanding of how the brain, mind and body works. The study is complex and requires a broad and deep knowledge of the various mechanisms and…

restaurant, teacher, and being a famous singer. As I have gotten older (and read less) my imagination fades away. In the video “Why Reading Matters” Rita Carters research shows that reading about when someone else is doing an action, it triggers the motor cortex part of the brain and the same action is “mirrored” in our brain as if we were doing the action (Carter 7:30). For example, if one reads about a character running, then their brain will send signals throughout the body that takes part in…
