Regional cerebral metabolic patterns demonstrate the role of anterior forebrain mesocircuit dysfunction in the severely injured brain
Open accessAbstract
Significance: Establishing consciousness in the human brain requires an ensemble activity of multiple cortical and subcortical structures. Following severe brain injuries, widespread deafferentation and neuronal death alter function across the corticothalamic system and its projections to the basal ganglia. In this paper, we test a theoretical model of a mesocircuit mechanism likely to arise in all severe brain injuries. Specifically, reduction of resting glucose metabolism within the central thalamus, striatum, and frontoparietal cortices and concomitant increases in metabolism within the globus pallidus as a result of disinhibition are proposed to arise across etiologies of injury. Here we verify this prediction and demonstrate a reversal of metabolic profile of central thalamus and globus pallidus that characterizes and indexes the patients’ behavioral level.

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.
