Tennant_and_Tchaikowsky_as_Hamlet_and_Yorick“… all of our brains – no matter who we are – react more strongly to negative events. The asymmetric response to positive and negative events is rooted in the brain’s processing of emotion. Negative events cause greater self-referential activity in the medial prefrontal cortex and also increased activity in the insula, which is responsible for noticing visceral sensations. Lastly, they also engage more of an emotional response in the amygdala and hippocampus”.
