Gamma tACS over the prefrontal and parietal cortices enhances episodic memory performance

These findings provide preliminary behavioral evidence that gamma-frequency tACS delivered to memory-related cortical regions is associated with differences in episodic memory discrimination at delayed time points. However, the results are based solely on behavioral measures, and replication with larger and more diverse samples, as well as studies incorporating neurophysiological recordings, will be necessary to clarify the underlying mechanisms and robustness of these effects.
