CORTEG: Foundation Models Enable Cross-Modality Representation Transfer from Scalp to Intracranial Brain Recordings
Researchers introduce CORTEG, a framework that adapts pretrained scalp-EEG foundation models to intracranial ECoG recordings, enabling brain-computer interfaces to learn across patients with minimal calibration time. The approach demonstrates competitive or superior performance on finger trajectory and audio envelope decoding tasks while reducing per-patient training requirements to 10-30 minutes.
