One central biological argument is related to cognitive differences between genders. In a 2008 study using functional magnetic reasoning imaging (fMRI) to monitor brain activity in participants, researchers found that men and women differ in neural responses when experiencing negative emotions. "Compared with women, men showed lesser increases in prefrontal regions that are associated with reappraisal, greater decreases in the amygdala, which is associated with emotional responding, and lesser engagement of ventral striatal regions, which are associated with reward processing" (McRae, Ochsner, Mauss, Gabrieli, & Gross, 2008).[10] The way that male and female brains respond to emotions likely impacts the expression of those emotions.
