with electrical stimulation during brain surgery penfield reported that patients
Wilder Penfield Penfield reported[12] that stimulation of the temporal lobes could lead to vivid recall of memories. Oversimplified in popular psychology publications, including the best-selling I'm OK – You're OK, this seeded the common misconception that the brain continuously "records" experiences in perfect detail, although these memories are not available to conscious recall. Reported episodes of recall occurred in less than five percent of his patients, though these results have been replicated by modern surgeons.[13][14] Penfield's hypothesis on this subject was revised in 1970.[15] His development of the Penfield dissector, the neurosurgical technique that produced the less injurious meningo-cerebral scar, became widely accepted in the field of neurosurgery and remains in regular use.
