Running Head: AMYGDALA & HYPERSOCIABILITY The Role of the Amygdala and Abnormal Social Behavior in Williams Syndrome Abstract Williams syndrome (WS) is a genetic neurodevelopmental disorder often paired with unique behavioral abnormalities like hypersociability‚ reduced fear and a tendency to approach strangers. The amygdala is an integral component of the neural network and has been implicated in social phenotype particularly in emotion and fear. Functional

This is not surprising as the exposure to ELS corresponds to the maturation period of several brain structures‚ including amygdala and hippocampus. Consequently‚ this interference with post-natal neuronal

This paper is my second assignment for physiological psychology. The first section of this paper critiques an article entitled “Ecstasy and Agony: Activation of the Human Amygdala in Positive and Negative Emotion”. This sections main point is to show that there is enough evidence indicating that the amygdala plays a critical role in negative human emotions. And the instrument of choice was PET. The second section of this paper critique’s an article entitled “Overactive Action Monitoring in Obsessive-Compulsive

tasks. The frontal lobe works together with the amygdala. This is the part of the brain which is linked with emotional memory. The prefrontal cortex (part of the frontal lobe) analyses a situation‚ such as a student about to walk into an exam hall to take an important exam‚ and if the individual’s actual coping ability conflicts with the individual’s perceived coping ability i.e. the student panics and feels they are not fully prepared‚ then the amygdala will highlight that there is a problem.

We also consider the role of the mPFC in a broader neural circuit for extinction that includes the amygdala and hippocampus.

Neuroimaging studies show that the brains of PTSD victims compared to those of healthy individuals are structurally and functionally different. The areas of significant changes are the hippocampus‚ amygdala as well as the prefrontal cortex. The symptoms PTSD victims face are thought to be a representation of the physical changes in these areas of the brain. As a result‚ we are granted the ability to localize brain functions and ultimately gain a better understanding of why and how disorders such

Fear may represent the most powerful motivator on the spectrum of emotions experienced by human beings. Instigating everything from escaping bodily harm to sweating profusely before an exam‚ fear substantially molds our cognition and our behaviors. Further supporting the fundamental nature of fear is its universality; all animals‚ including primitive insects and worms‚ have demonstrated fear responses to certain stimuli (“Fear in the Brain”‚ 2003). Despite its ubiquity‚ fear signified an incredibly
