Previous studies in animals have shown that activity in the habenula of the brain leads to avoidance because it suppresses dopamine, a brain chemical that typically increases feelings of motivation. Habenula cells were found to activate when bad things happened or were expected. In a current study, published in the Proceedings of the National Academy of Sciences, scientists from the University College London found that this same tiny part of the brain (half the size of a pea) tracks predictions regarding negative events, and then essentially demotivates us humans too.  Since the habenula has also been associated with depression, understanding this brain function could help in the development of better treatment.
