Desirability

Neuropsychology

While desires are often classified as emotions by laypersons, psychologists often describe desires as ur-emotions, or feelings that do not quite fit the category of basic emotions. For psychologists, desires arise from bodily structures and functions (e.g., the stomach needing food and the blood needing oxygen). On the other hand, emotions arise from a person's mental state. A 2008 study by the University of Michigan indicated that, while humans experience desire and fear as psychological opposites, they share the same brain circuit. A 2008 study entitled "The Neural Correlates of Desire" showed that the human brain categorizes stimuli according to its desirability by activating three different brain areas: the superior orbitofrontal cortex, the mid-cingulate cortex, and the anterior cingulate cortex.
