Psychobiology Personality determines the character of the human being. There are many Personality tests are examined by our scientist to determines the traits in human beings. Do the Avoidant Personality test right now! How personality matters in thinking of the human being. According to research neuroticism is one of the good studies of personality traits. If we talk about a person who has a high composition of neuroticism is susceptible to anxiety, depression, stress or many more mental conditions.

Now, the question arises in your mind what is the major cause of high neuroticism, when the amount of benzodiazepine in amygdala decrease then neuroticism increase in your body which will generate all these mental conditions.

Similarly, Sensation Seeking behavior is another personality trait which also has high social relevance. Those have high on sensation seeking to be likely to be under-aroused. Their Ascending Reticular Activation System (ARAS) is below the optimum level of arousal. Many Studies shows that autonomic nervous system (ANS) function differences introverts and extroverts have used skin conductance, heart rate, and EEG measures.

According to the psychobiology of personality have found the simple sensory stimulation do not elicit any difference between introverts and extroverts in term of tonic levels of electrodermal activity.

However, when challenged by task demands, the skin conductance level has been found to be higher for extraverts at a higher stress level. Contrarily the skin conductance level was higher in introverts for lower stress levels.

There is a direct relationship between the personality and electrical activities of the brain have also been studied. The introverts and extroverts have been found to be different with respect to alpha recording from the posterior regions of the skull. High arousal level is represented by low amplitude and high frequency ranging between 8-13 Hz.

There is a direct correlation between blood flow and neuroticism was not significant. The findings suggest the inverse relationship between extraversion and general cortical arousal. Couples of studies have correlated PET- glucose metabolic rate (GMR) and scores of Eysenck Personality Questionnaire. The findings show a positive correlation between extraversion and GMR in frontal and temporal areas of the brain.

If you are dreaming like there is no relation between extraversion and increased activation to positive stimuli. Now, you are wrong, because there is a positive correlation between extraversion and increased activation to positive stimuli in the frontal and temporal lobes, and parts of the caudate, putamen, and amygdala.

If you see this in a border picture form then you will find that the behavior of an individual is under the control of executive functions. Our reaction to any stimuli involves planning, spatiotemporal segmentation, and execution.

Adjustment of an individual is also appraised by their ability to understand and interrupt behaviors of others in terms of deciphering other person’s intentions and thoughts.  fMRI studies show the superior temporal gyrus, amygdala and prefrontal cortex are involved in processing social information.
