This article provided evidence that personality and emotion are related to brain activity and reactivity.

Study participants

The study participants that are fourteen right-handed female aged 19-42 years participated in this study. The data were collected from the participants to analyze the role of emotions and emotion memory on activation patterns in the brain (Canli et al. 2001).

In Emotional stimuli method, the participants were requested to see 20 positive and negative pictures. As explained by Canli et al. (2001), Negative pictures include anger, crying and guns whereas the positive pictures include happy couple and puppies. In a method, Magnetic Resonance Imaging in which data was collected using in 1.5 General Electric MR Imager. In Correlation Maps method was used for analyzing the correlation between negative pictures and brain activity and positive picture and brain activity.

Results

The results found in this article include negative emotions are related to different parts of the brain such as Left frontal lobe and left middle gyrus. In addition, it is also found that the negative emotions are related to different parts of brains such as right frontal gyrus, precentral gyrus in the left, temporal lobe and cingulate gyrus in the right, globus pallidus in the left and amygdala in the right. In this article, it is also found that positive emotions are related to brain parts such as temporal and frontal gyrus in the middle of the left side.Another part of the brain that is associated with positive emotion in the brain is the frontal gyrus in the middle of the right side. The different personality measures such as neuroticism and extraversion are significantly correlated with activation in the brain. As discussed by Canli et al. (2001), extraversion personality is associated with the positive emotion thereby impacting the brain location such as cortical and subcortical. In addition, it is also found that neuroticism is associated with activation of negative emotions in the brain. The different parts of the brain that are affected by negative emotions include temporal and frontal lobes of the brain. Moreover, it is also found that the part of the brain that is influenced by both negative and positive emotions is frontal cortex that is the middle frontal gyrus in the left part of the brain.
