Abstract

By means of extracellular recordings, individual norepinephrine-containing neurons in the locus coeruleus of unanesthetized behaviorally responsive rats and squirrel monkeys were found to respond to specific sensory and behavioral conditions. In rats, distinct clusters of action potentials followed the presentation of various nonnoxious auditory, visual, or somatosensory stimuli at latencies of 15-60 msec. Increased discharge rates were also seen during periods of spontaneous electroencephalogram arousal in both species. In monkeys, these cells responded most vigorously to complex arousing stimuli such as a preferred food. Because the noradrenergic innervation of most forebrain regions arises from the locus coeruleus, these results allow prediction of situations under which this massive projection system would be active and suggest a physiological role for this chemically identified network in specific behavioral processes.

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.
