-The purpose of the experiment was to determine which part of the brain different people use when accidentally bumped into. The experiment was done in various places to people of different genders so the experiment was more random. The prefrontal cortex was the part of the brain that reasoned with what was happening; when people use this part of their brains their reactions are milder. The amygdala (part of the limbic system) was the part of the brain that triggered an angry or annoyed response.…
Several years ago, my stepbrother, Travis, lost the tips of two fingers on his right hand in a work accident. The first time he tried to shoot a gun after the accident, he did not realize his fingers did not even reach the trigger. That is just one example of phantom limb. Most people with phantom limb have what is called phantom limb pain. Phantom limb pain refers to ongoing painful sensations that seem to be coming from a part of the limb that is no longer there (“Managing Phantom Pain,” 2016). Even though the limb is gone, the pain is real. Phantom limb pain has different causes, different symptoms and different treatments.…

The limbic system and prefrontal cortex play an extensive role in human behavior. The limbic system is a set of structures within the brain that controls human emotions and memories; intensifying during puberty. On the other hand, the prefrontal cortex is responsible for regulating behavior and thought analysis. This is developed later than the limbic system which has already begun developing during puberty as stated earlier. Due to the differences in developmental time, the extremities such as, controlling our temper when we feel angry, are enhanced.…
There are two main biological explanations to aggression, neural and hormonal. The neural explanation is the serotonin and dopamine neurotransmitters and how they affect our aggression; the hormonal mechanisms are the testosterone and cortisol chemicals.…

The function and structure of the brain has long been implicated in the explanation of violent behaviour. From cases studies as early as 1848, in which head injuries resulted in changes of personality and behaviour. The prefrontal cortex was identified as a region of interest as specific head wounds to this area resulted in increased aggression and violence. The improvement of neuropsychological testing and brain imaging has further described the role the prefrontal cortex plays. Current theory and research indicates that the amygdalo-hippocampal complex (AHC) is implicated in the control of aggression and that the prefrontal cortex regulates…
This activity will increase your understanding of the different structures of the nervous system and brain. During the Web activity, you will view a variety of structures of the brain and nervous system and label each with the appropriate term. You will use this document to write a description for the terms you used in the activity.…
Aggression in humans has been associated with low levels of serotonin and high levels of dopamine. Usually, serotonin has a calming effect, which inhibits aggression. When serotonin levels are low, this inhibitory effect is removed and people are less able to control their aggressive behaviour.…
The amygdala, shaped like an almond, is a set of nervous tissue that is located in the interior of the temporal lobe. The function of the amygdala is to regulate fear and aggression. Patients with BPD are found to have a much smaller amygdala as opposed to someone who does not, thus causing it to be overactive. The more overactive the amygdala is the higher the intensity of the emotion is experienced and the longer period of time it takes the person to calm down.…

Another factor pointing towards the idea that psychopathy is genetically determined was identified by in a study at University of Wisconsin, Madison. When dealing with the terrible notion that some people take pride in murdering others, one should expect some abnormality in the brain, the immediate source of psychopathic traits. Scans of the brain revealed that psychopathy in criminals was associated with reduced connectivity between the amygdala, a part of the brain that processes negative stimuli, and the ventromedial prefrontal cortex (vmPFC), a region in the front…
