abstract = "Areal distributions on cerebral cortex of several types of non specific activity were compared in cat. Spontaneous spindle bursts in pentobarbital and cerveau isol{\'e} preparations, nonspecific cortical association responses evoked by peripheral stimuli in the chloralosed animal, and short latency cortical responses evoked by single shock stimulation of the midbrain reticular formation were all found to have essentially identical cortical distributions. These occurred in four major foci, two on the middle suprasylvian gyrus, one on the anterior lateral gyrus, and one on pericruciate cortex surrounding the cruciate sulcus.",

note = "Funding Information: Forty-four cats were used. Four different types of preparation were employed: pentobarbital (40mg/kg, IP), cerveau isol6, chloralose (70 mg/kg, IP) with subsequent administration of pentobarbital, and chloralose with subsequent brainstem transection to yield a cerveau lso16. The cerveau isol6 was prepared, using ether, by spatula transection under stereotaxic control at the level of the inferior colliculus following removal of the cerebellum. Body temperature was maintained at 38°C by a thermostatic heating system. The hemisphere, after exposure and removal of dura, was kept moist in a saline-soaked cotton chamber. A stainless steel recording electrode 0.3 mm in dia., insulated except at the tip, was mounted on a movable carrier fitted with rectangular coordinates calibrated in millimeter units. This assembly was mounted in a holder in which the animal's head was rigidly supported. For monopolar recording the indifferent electrode 1This work was supported by Research Scientist Award MH-06650 from the National Institute of Mental Health (RFT), research grant NS-07661 from the National Institutes of Health (RFT), predoctoral fellowship MH-42521 from the National Institute of Mental Health (RTR), and Biological Sciences Research Training Grant MH-11095 from the National Institute of Mental Health. ~Dr. Hicks collaborated on certain phases of the project while on leave from the Department of Psychology, Howard University.",
