Interference with episodic memory retrieval following transcranial stimulation of the inferior but not the superior parietal lobule

► We examined the causal effect of repetitive TMS delivered at left parietal sites on episodic retrieval. ► A decrease of sensitivity for item recognition was observed for AG compared to SPL stimulation. ► A change in the criterion of source memory was observed for AG compared to SPL and sham stimulation. ► Inferior parietal lobule has a causal role in episodic retrieval. ► AG stimulation may have affected the weighing of the retrieved information for source attribution.
