Localizing Cortical Reward Prediction Error Signals Using Combined EEG and fMRI

ACC may be involved in reward processing, which is reflected in EEG as 'reward positivity' . We aim to eatablish which part of the brain is producing the reward positivity. A novel design--a combined fMRI/EEG study with a modified time-estimation task will be conducted to explore this question, which will also help clear the role of ACC in reinforcement learning.
