This is the first time, however, that a positive connection has been made between dopamine and the ability to recognise emotions in others.
In a new study, published in the Journal of Neuroscience, a team in the University’s Centre for Human Brain Health showed that manipulating levels of dopamine affected emotion recognition. More specifically,…
