EEG dataset from a reinforcement learning study of 50 healthy controls, 25 tested after a sad mood manipulation and 25 after a happy mood manipulation. Participants completed a probabilistic selection task with training and testing phases. The task was adapted from a Parkinsonism reinforcement learning paradigm, and the mood manipulation was delivered before each training block.

EEG recordings from participants receiving a series of laser stimuli while rating pain intensity. After an initial calibration to find the laser energy that yielded an average rating of 7, each participant received 30 laser stimuli and verbally rated each one on a 0-10 pain scale. The dataset supports research on the neural correlates of pain perception.
