Abstract

Neural and cortical plasticity represent the ability of the brain to reorganize its function in response to a challenge. Plasticity involves changing synaptic activity and connectivity. Long-term-potentiation is one important mechanism underlying these synaptic changes. Disturbed neuronal plasticity is considered to be part of the pathophysiology of schizophrenia and has been linked to the different clinical features of this severe illness. The aim of the present study was to investigate nonfocal cortical plasticity and cortical excitability in recent-onset and multi-episode schizophrenia compared with healthy subjects. Nonfocal cortical plasticity can be induced in the motor cortex of healthy subjects with anodal transcranial direct current stimulation. Animal and human research indicates that this long-term-potentiation-like plasticity is glutamate-dependent and that these plasticity shifts can last for several hours. Transcranial direct current stimulation-induced plasticity was monitored by transcranial magnetic stimulation-generated motor evoked potentials. Well-characterized transcranial magnetic stimulation protocols were applied to determine the physiological basis of plasticity changes. Multi-episode schizophrenia patients showed significantly reduced long-term-potentiation-like plasticity compared to recent-onset schizophrenia patients and healthy controls. All schizophrenia patients demonstrated reduced cortical inhibition. Our results indicate that the long-term-potentiation-like plasticity deficit in schizophrenia patients is related to the disease course. Disturbances of N-methyl-d-aspartate, gamma-aminobutyric acid and dopamine receptors may account for this plasticity deficit. LTP-like plasticity deficits might be related to disturbed information processing in schizophrenia patients.

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.
