Prenatal developmental disturbances in the limbic allocortex in schizophrenics

Jakob, H., Beckmann, H.·1986·Journal of Neural Transmission

Abstract

Sixty-four autopsied brains of schizophrenic patients were neuropathologically examined and compared with 10 brains of non-schizophrenic controls. Clinical diagnoses were established retrospectively according to the Research Diagnostic Criteria and the International Classification of Diseases. We found: brains without deviations of the sulcogyral pattern of the temporal lobe or abnormal gross configuration (n = 22); brains with abnormal sulcogyral pattern of the temporal lobe or abnormal gross configuration (n = 42): with definite cytoarchitectonic abnormalities of the rostral entorhinal region in the parahippocampal gyrus and, in 16 cases only, in the ventral insular cortex (n = 20); with equivocal changes of the cytoarchitecture in these two regions (n = 22). Generally, these anatomical abnormalities were asymmetric. The histological findings in the two limbic regions consisted mainly of poorly developed structure in the upper layers, with a heterotopic displacement of single groups of nerve cells in the entorhinal region. Particularly, the disturbed structure of the second layer Pre-alpha in medial and central fields of the entorhinal region, situated in the parahippocampal gyrus (group 2a), suggests a disturbance of neuronal migration in a later phase of cortical development.

  • In the medial temporal lobe, most abnormalities are found in superficial layers, such as atypical clustering of neurons in layer 2 of entorhinal cortex.

    “In the medial temporal lobe, most abnormalities are again found in the superficial layers; such as atypical clustering of neurons in layer 2 of entorhinal cortex (Jakob and Beckmann, 1986; Arnold et al., 1991; Falkai et al., 2000)”

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.
