Introduction Obsessive-Compulsive Disorder OCD is characterized by the world health organization as a major cause of mental disturbance. Biological approach is one of the viewpoints in the field of etiology of psychological disorders, especially the OCD. Losing the interaction between the two systems can also result in a similar outcome. Hence, intermediary mechanisms such as disgust sensitivity have been proposed for a better understanding of the relationship between brain-behavioral systems and OCD. Disgust as a negative and inclusive emotion involves a feeling of intense hatred and reluctance, which encompasses different physiological, cognitive, and behavioral dimensions.

The neural correlates underlying the influence of emotional interference on cognitive control remain a topic of discussion.

According to appraisal theory, our interpretation of a situation causes an emotional response that is based on that interpretation. Researchers have developed several theories of how human emotions arise and are represented in the brain. The central question that the appraisal theory seeks to answer is why different people have different perceptions of and emotional reactions to the same situations. For example, if a person goes on a romantic date and perceives this date as positive, they might feel happiness, joy, giddiness, excitement, or anticipation because they have appraised this event as one that could have positive effects. Magda Arnold — was an American psychologist who coined the term appraisal to refer to the cognitive processes preceding the elicitation of emotion. According to Arnold, an initial appraisal begins the emotional sequence by arousing both the appropriate physiological reactions and the emotional experience itself.

But how does such social information affect the neural generation of affective experience, and are the brain mechanisms involved distinct from those that mediate other types of expectation effects?

Brains Do It: Lust, Attraction, and Attachment

Recent years have witnessed the emergence of powerful new tools for assaying the brain and a remarkable acceleration of research focused on the interplay of emotion and cognition. This work has begun to yield new insights into fundamental questions about the nature of the mind and important clues about the origins of mental illness. In particular, this research demonstrates that stress, anxiety, and other kinds of emotion can profoundly influence key elements of cognition, including selective attention, working memory, and cognitive control. Often, this influence persists beyond the duration of transient emotional challenges, partially reflecting the slower molecular dynamics of catecholamine and hormonal neurochemistry.

Brains Do It: Lust, Attraction, and Attachment

Thousands of answers have been offered—but surprisingly few by biologists, including brain scientists. While scientists regard other complex emotional states such as depression, anxiety, or fear as complex, but not unfathomable, love is relegated to the poets and songsters. Certainly such love can be a joyous state, but it is also capable of producing deeply disturbing, even dangerous results. At least 25 percent of homicides in the United States involve spouses, sexual partners, or sexual rivals.

Neurobiological research with animals strongly suggests that the brain systems which mediate emotion overlap with those that mediate cognition to such a.
