When Doors of Perception Close: Bottom-up Models of Disrupted Cognition in Schizophrenia

Open access
Javitt, Daniel C.·2009·Annual Review of Clinical Psychology

Abstract

Schizophrenia is a major mental disorder that affects approximately 1% of the population worldwide. Cognitive deficits are a key feature of schizophrenia and a primary cause of long-term disability. Current neurophysiological models of schizophrenia focus on distributed brain dysfunction with bottom-up as well as top-down components. Bottom-up deficits in cognitive processing are driven by impairments in basic perceptual processes that localize to primary sensory brain regions. Within the auditory system, deficits are apparent in elemental sensory processing, such as tone matching following brief delay. Such deficits lead to impairments in higher-order processes such as phonological processing and auditory emotion recognition. Within the visual system, deficits are apparent in functioning of the magnocellular visual pathway, leading to higher-order deficits in processes such as perceptual closure, object recognition, and reading. In both auditory and visual systems, patterns of deficit are consistent with underlying impairment of brain N-methyl-d-aspartate receptor systems.

  • MMN has been tied to impaired neurotransmission at NMDARs based upon both intracranial and surface recordings in non-human primates and ketamine challenge studies in healthy human volunteers.

    “MMN has been tied to impaired neurotransmission at NMDARs based upon both intracranial (54) and surface (55) recordings in non-human primates and ketamine challenge studies in healthy human volunteers (rev. in 3).”
  • Deficits in MMN generation are associated with impairments of basic auditory discrimination, such as tone matching and auditory spatial discrimination.

    “On a behavioral level, deficits in MMN generation are associated with impairments of basic auditory discrimination, such as tone matching (3) and auditory spatial discrimination (49)”
  • Deficits in MMN generation were first reported in the early 1990s and have since been a widely replicated neurophysiological finding in schizophrenia.

  • Low level visual deficits cascade up the system to undermine higher order cognitive impairments, as in the auditory system.

    “supporting recent suggestions that low level visual deficits cascade up the system to undermine higher order cognitive impairments, as in the auditory system (3).”
  • Deficits in MMN are tied to impairments in both orientation to critical environmental events and detection of the sensory modulations that are used to communicate social information such as emotion or attitude by tone of voice.

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.
