Serotonin, reward, and punishment

Our new paper shows:

- that choice values for reward (money) and punishment avoidance (pain) are integrated in ventromedial prefrontal cortex.

 - that serotonin modulates the 'exchange rate' of their common currency, but surprisingly by selectively modulating reward value, and not punishment value as previously hypothesised.

See 'Serotonin selectively modulates reward value in human decision-making' :
