Hippocampus-targeted temporal interference stimulation (TIS) during inter-practice rest enhances micro-offline gains in a motor sequence learning task in 32 young healthy adults.
- Why it matters: The hippocampus is implicated in motor sequence learning and consolidation across timescales, but causal evidence in healthy humans is limited because non-invasive methods struggle to reach deep structures.
- What they did: In two within-subject experiments (n = 64 total), participants received active (5 Hz envelope) or control (0 Hz envelope) hippocampal-targeted TIS either during task practice or during short rest intervals, with performance measured over micro-offline and 24-hour macro-offline intervals.
- The result: TIS during inter-practice rest significantly increased micro-offline performance gains versus control, did not produce group-level 24-hour retention effects, and stimulation-induced micro-offline gains predicted larger overnight improvements.
