Using a single-case experimental design with alternating stimulation and non-stimulation phases, the study investigated whether personalized tACS guided by individual EEG profiles enhances naming abilities and sustains improvements after intervention. EEG data were collected during picture naming tasks at seven timepoints (weeks 1, 2, 4, 6, 8, 12, and 20) and processed according to BIDS standards.\",\n  \"methods_description\": \"EEG recordings were acquired using Starstim-32 during picture naming tasks at seven timepoints (weeks 1, 2, 4, 6, 8, 12, and 20). tACS was applied during alternating two-week phases with frequency and montage personalized based on initial EEG profiles. A single-case experimental design (ABAB type) was employed with 24 naming sessions and 6 EEG recording sessions per participant.
