EFFECTS OF CHRONIC LESIONS IN CENTRAL CEPHALIC BRAIN STEM OF MONKEYS

FRENCH, J. D.·1952·Archives of Neurology And Psychiatry

Abstract

THERE has been shown to exist in the median cephalic portion of the brain stem of cats1and monkeys2an area comprising the midbrain tegmentum, the subthalamus and hypothalamus and the medial portion of the thalamus which subserves a specialized function in the response of the animal to sensory stimuli. This area can be readily excited by peripheral stimulation, such excitation, or that produced by direct stimulation with a probing electrode, arousing the sleeping animal to wakefulness and altering its electroencephalogram in a manner consistent with such a change. The evidence suggests that this activating system is of particular importance in initiating and maintaining an alert or attentive state in the animal, rendering it capable of reacting adaptively to stimuli in a way impossible in sleep. Lindsley and associates3have observed that lesions placed so as to destroy a significant portion of this area in cats were

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
