Physiologists of Mind: Brain Scientists from Gall to Penfield - Stimulation of the Conscious Human Brain
3 important questions on Physiologists of Mind: Brain Scientists from Gall to Penfield - Stimulation of the Conscious Human Brain
What was Penfields theory on the location of the aura that epilepsy patients get before a seizure?
Penfield hypothesized that an aura results from the earliest activation at the focus, before it spreads far enough to cause the convulsions and the epileptic seizure. Further, he thought the specific content of an aura might depend on the location of the focus; an aura of tingling in the left arm, for instance, might be associated with a focus in the right sensory strip.
What did Donald O. Hebb relate learning and other behavior to?
Donald O. Hebb wrote the book The Organization of Behavior. This book related learning and other behavior to the hypothetical functioning of “neurological networks” in the brain that he called cell assemblies.
What was the conclusion of Scolville and Milner after undertaking a comparative case study of H.M. and nine other patients?
They undertook a comparative case study of H.M. and nine other patients who had undergone variations of the epilepsy surgery, differing only with respect to how much of the hippocampal region was destroyed. Patients like H.M. with the most extensive excisions of the hippocampus showed the most profound loss of recent memory. Some other patients, whose hippocampal regions were spared significant damage, showed completely intact memory. Scoville and Milner concluded that the ability to form recent memories somehow resided within this particular brain structure.
