Multiphasic temporal dynamics in responses of midbrain dopamine neurons to appetitive and aversive stimuli

The transient response of dopamine neurons has been described as reward prediction error (RPE), with activation or suppression by events that are better or worse than expected, respectively. However, at least a minority of neurons are activated by aversive or high-intensity stimuli, casting doubt on...
