My dearest @steepup :D How wonderful to see you here!

Ok, let's just clarify a few things here :)

schadenfreude is not a neuropsychological term for envy. Rather it is a rewarding feeling that positively correlate to envy. For example, the more we envy someone, the more intense the pleasure we feel to see them undergoing tribulations, and that is schadenfreude. Ok? :)

The mechanisms of envy itself is seen on the dACC area.

Anyone can have their ventral striatum activity measured by means of an fMRI. But, my guess is that it would be quite costly to implement that in homicidal departments of the police force.

As well as you, I do find very intriguing as well that within our brains there is a mechanism that rewards us at the expense of another's misfortunes. Human are truly incredibly complex beings!

Thank you for taking the time to read and leave your feedback about this topic my dear. I am very glad to hear you like this post :D
