This study shows that reward prediction errors in the ventral striatum predict episodic memory strength and that functional connectivity between brain regions increases with RPE value during learning.

The paper tests a computational model of midfrontal theta oscillations in rule switching using EEG data from a probabilistic reversal learning task, finding that theta power and phase coupling correlate with negative prediction errors.

This study tests if theta-frequency tACS modulates declarative learning via reward prediction errors but finds no effect.
