Electrocorticography and depth electrodes — millimetre-scale human recordings that reveal high-frequency dynamics surgery can see.
Key takeaways
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. Educational neuroscience context only — not medical advice. Intracranial EEG is performed in specialised clinical settings for indicated patients.

Quick FAQ What is intracranial EEG iEEG/ECoG? Electrodes on or in the brain during clinical mapping — millimetre-scale timing that scalp EEG blurs. Teaching description of published methods.
When did Penfield-era cortical stimulation map speech? Mid-20th-century Montreal work made awake mapping famous. Modern grids and stereo-EEG continue the classroom story without copying an OR checklist.

Seven ways into this topic
Frequently asked questions What is intracranial EEG iEEG/ECoG? Electrodes on or in the brain during clinical mapping — millimetre-scale timing that scalp EEG blurs. Teaching description of published methods.
When did Penfield-era cortical stimulation map speech? Mid-20th-century Montreal work made awake mapping famous. Modern grids and stereo-EEG continue the classroom story without copying an OR checklist.
Is this a guide to implant surgery or dosing? No. Educational methods atlas. Not a diagnosis, implant protocol, or medication dose.
What can iEEG resolve that scalp methods smear? When and where populations engage during perception, speech, memory or movement — at scales scalp EEG averages away.
Research score 82 — a clinic ranking? No. Editorial 0-100 in this methods field. Compare with EEG, fMRI and MEG neighbours.
Why do overview pages get clicks? They name ECoG sites and cortical surface mapping early. Keep reading Overview, Anatomy, Function; do not self-schedule a procedure.
What reusable tool sits on brain pages? Atlas dual-view: pin a cortical label beside a deep structure while you read iEEG limits — teaching, not targeting.
Any number to keep? Scores are editorial. Clinical sampling density is case-specific in the literature — this site does not publish an OR recipe.
