Intracranial EEG (1950): Cortico-cortical white matter · 1950 · l-eeg-11

Intracranial EEG records electrical activity from electrodes on the cortical surface (ECoG) or in depth (stereo-EEG / SEEG). It offers millimetre spatial scale and kilohertz temporal bandwidth unavailable to scalp EEG or fMRI. Intracranial EEG records electrical activity from electrodes on the cortical surface (ECoG) or in depth (stereo-EEG / SEEG). It offers millimetre spatial scale and kilohertz temporal bandwidth unavailable to scalp EEG or fMRI.

Clinically it maps seizure onset and eloquent cortex before epilepsy surgery; scientifically it reveals high-gamma activity tied to cognition. Coverage is sparse and ethical constraints are strict — not a general “brain reading” tool. Intracranial EEG records electrical activity from electrodes on the cortical surface (ECoG) or in depth (stereo-EEG / SEEG). It offers millimetre spatial scale and kilohertz temporal bandwidth unavailable to scalp EEG or fMRI.

Educational neuroscience context only — not medical advice. Intracranial EEG is performed in specialised clinical settings for indicated patients. Intracranial EEG records electrical activity from electrodes on the cortical surface (ECoG) or in depth (stereo-EEG / SEEG). It offers millimetre spatial scale and kilohertz temporal bandwidth unavailable to scalp EEG or fMRI.
