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.
