Anxiolytic action on the behavioural inhibition system implies multiple types of arousal contribute to anxiety

McNaughton, Neil, Gray, Jeffrey A.·2000·Journal of Affective Disorders

Abstract

According to "The Neuropsychology of Anxiety" [Gray, J.A., 1982, The Neuropsychology of Anxiety: An Enquiry into the Functions of the Septo-hippocampal System, Oxford University Press, Oxford; Gray, J.A., McNaughton, N., 2000, The Neuropsychology of Anxiety: An Enquiry into the Functions of the Septo-hippocampal System, 2nd ed., Oxford University Press, Oxford], anxiolytic drugs of all types act on a behavioural inhibition system, the most important neural component of which is the septo-hippocampal system. Anxiolytics affect septo-hippocampal function by impairing the subcortical control of hippocampal "theta" activity - the principle response of the septo-hippocampal system to arousal. Our recent experiments show that there are multiple systems controlling theta activity and that anxiolytics act on several, but not all, of these systems. This pattern of results implies that there are many different types of arousal, only some of which appear to contribute to the generation of anxiety in normal subjects and to the etiology of pathological anxiety.

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.
