• Intracranial Recordings in Epilepsy: an Approach to Understanding the Neural Mechanisms of Social Cognition (2025, unknown): “In the 1950 s, Dr. Wilder Penfield used iES in the 1950 s to map the sensory and motor cortices in epilepsy patients [22] and more recently, this technique has been employed to reveal the distributed organization of language networks [23].”
• Simultaneous invasive and non-invasive recordings in humans: A novel Rosetta stone for deciphering brain activity (2024, unknown): “Since Penfield ’ s seminal mapping of the homunculus (Penfield and Boldrey, 1937), stimulation with simultaneous intracranial EEG recordings has become invaluable as a research and clinical tool.”
• Why does invasive brain stimulation sometimes improve memory and sometimes impair it? (2024, unknown): “Early work [56,57] showed that when direct electrical stimulation was applied to similar locations on the surface of the sensory cortex, different patients experienced opposite sensations of involuntary vocalization or a temporary inability to speak, and in another case, numbness or feeling…”
