Beta and high gamma oscillations mark positive reward valence, indicating the likelihood of rewards during probabilistic learning tasks.
Changes in oscillation activity were correlated with behavioral performance, highlighting their significance in decision-making.
Local field potential measurements in rats demonstrated how networks adapt to reward feedback during task performance.
Optogenetic stimulation at beta frequencies affected task outcomes, suggesting oscillatory dynamics are crucial for learning under uncertainty.
