Data were collected across 3 recording sessions using a Brain Products EEG system sampled at 5000 Hz, yielding 90 scans with a total of approximately 10.7 hours of recording. The study investigates the interaction between tDCS-induced neuromodulation and motor imagery-related brain activity, with potential applications in understanding cortical plasticity and brain-computer interfaces.\",\n  \"methods_description\": \"EEG data were recorded using a Brain Products system at 5000 Hz sampling rate with 60 Hz line noise present.
