A more complete definition of the normal sleep pattern of the monkey Macaca nemestrina is attempted and the electrical activity of the cortex and various deep brain structures during sleep is investigated by means of the electroencephalogram and the averaged evoked response to a sound stimulus.

In cats with electrodes chronically implanted in selected nuclei of limbic, sensory and diffuse projection systems, anesthetic concentrations of enflurane induced bursts of high voltage spike activity separated by prolonged periods of interictal silence, and these electrographic effects to the anesthetic state are discussed.

Electroencephalographic patterns during intracardiac surgery using cardiopulmonary bypass; a comparison of two anesthetic agents.
The purpose of this paper is to discuss the electroencephalographic records thus obtained from 25 patients during cardiopulmonary-bypass procedures, using the oxygenator, obtained dur-ing the year 1957. Expand
Central nervous system effects of althesin (CT 1341): A new steroid anaesthetic agent
A spontaneous activity of various structures representative of the three principal systems considered of importance to the anaesthetic state was observed in chronic preparations and evoked potentials elicited by peripheral somatic stimulation were recorded in acute experiments. Expand
Open-Heart Surgery: Neurologic Findings and Electroencephalographic Patterns Before, During, and After Open-Heart Surgery (Two-Year Follow-Up)
The nature of the electroencephalograms taken before, during, and after open-heart surgery in 1957 and 1958 and their relationship to pre- and postoperative neurologic findings are described. Expand
Electrographic studies of isoflurane (Forane).
Abstract In cats with electrodes chronically implanted in selected structures of limbic, sensory and diffuse projection systems, anaesthetic concentrations of isoflurane (Forane ® ) inducedExpand
Electrographic alterations induced in limbic and sensory systems during induction of anaesthesia with halothane, methoxyflurane, diethyl ether, and enflurane (Ethrane).
A definite spontaneous activity pattern of various subcortical structures indicating onset of analgesia could be established only for enflurane, and an increased susceptibility of the structures of the limbic system to the effect of halogenated compounds was demonstrated. Expand
