According to the findings of various scientific studies, individuals with depression show significantly less brain activation when shown pictures of humans expressing strong emotions than those without depression. These studies have used various neuroimaging techniques, such as functional magnetic resonance imaging (fMRI), to measure brain activity in response to emotional stimuli. The results of these studies have shown that individuals with depression tend to have less activation in the brain regions involved in emotional processing, such as the amygdala and the prefrontal cortex, compared to individuals without depression. This difference in brain activity may explain why individuals with depression often have difficulty recognizing and responding to emotional cues in social situations. -neuroimaging
