Development of the prefrontal cortex during adolescence: Insights into vulnerable neural circuits in schizophrenia

Lewis, D·1997·Neuropsychopharmacology

Abstract

Multiple lines of evidence suggest that the prefrontal cortex is a site of dysfunction in schizophrenia. In addition, one of the characteristics of this disorder is the tendency for clinical symptoms to appear first during late adolescence or early adulthood. Recent studies in nonhuman primates have shown that the connectivity of the prefrontal cortex is substantially refined during adolescence, suggesting that these developmental changes may be critical for the appearance of the clinical features of schizophrenia. This article reviews data demonstrating that these late developmental changes are selective for particular neural elements in the prefrontal cortex and that they are synaptically linked. It is suggested that these neural elements comprise a functional circuit that is likely to be especially vulnerable in schizophrenia, a hypothesis that can be directly tested in postmortem studies.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Animal and post-mortem human literature suggests an overexpression of receptors for serotonin, dopamine, adrenergic, and endocannabinoids, a peak in density of interneurons, and an increase in levels of GABA during adolescence.

    “Animal and post-mortem human literature suggests an overexpression of receptors for serotonin, dopamine, adenergic, and endocannabinoids (Lidow and Rakic 1992), a peak in the density of interneurons (Anderson, Classey et al. 1995; Lewis 1997; Erickson and Lewis 2002), and an increase in levels of GABA (Hedner, Iversen et al. 1984).”

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.
