Another simple method for the simultaneous cinematographic recording of the patient and his electroencephalogram during seizures

History of the Early Development of Electroencephalography and Clinical Neurophysiology at the Montreal Neurological Institute: The First 25 Years 1939-1964

“…We were soon able to acquire a vast amount of photographic records of unit and surface electrical activity from different cortical areas in monkeys, asleep and awake, and during the formation of conditioned responses to various forms of stimuli (Figures 9a and b) The result from the microelectrodes were clear cut, with little useful information coming from the surface electrocorticograms taken simultaneously. Descriptions of the firing of single cortical cells in the unanesthetized monkeys during sleep and waking, and during the establishment of conditioned reflexes were presented, in part, with Ricci and Doane at the "IVth International EEG Congress" in Brussels in 1957 82 and at the Ciba Symposium on "The Neurological Basis of Behavior" in London in 1958. 86 Finally a more complete presentation of our results was presented at the "Moscow Colloquium on Electroencephalography of Higher Nervous Activity" in 1958.…”
