Abstract

Although schizophrenia is associated with impairments in social cognition, the scope and neural correlates of these disturbances are largely unknown. In this study, we investigated whether schizophrenia patients show impaired functioning of the mirror neuron system (MNS), as indexed by electroencephalographic (EEG) mu (8-13 Hz) suppression, a hypothesized biomarker of MNS activity that is sensitive to the degree of social interaction depicted in visual stimuli. A total of 32 outpatients and 26 healthy controls completed an EEG paradigm that included six action observation or execution conditions that differed in their degrees of social interaction. Participants also completed a validated empathy questionnaire. Across both groups, we found a significant linear increase in mu suppression across the conditions involving greater levels of social engagement and interaction, but no significant group or interaction effects. Patients self-reported diminished empathic concern and perspective taking, which showed some moderate relations to mu suppression levels. Thus, the schizophrenia group showed generally intact modulation of MNS functioning at the electrophysiological level, despite self-reporting empathic disturbances. The disturbances commonly seen on self-report, performance, and neuroimaging measures of mentalizing in schizophrenia may largely reflect difficulties with higher-level inferential processes about others' emotions, rather than a basic incapacity to share in these experiences.

  • Neuroimaging and TMS studies of the mirror neuron system in schizophrenia during action observation and execution disagree, reporting intact, reduced, altered, or increased activity.

    “Some imaging and transcranial magnetic stimulation (TMS) studies find intact activity [14][15][16][17] in the mirror neuron system (MNS)-which is thought to form the neural basis of imitation [18][19][20][21] -during action observation and execution; while others find this activity to be reduced, 22,23 altered, 13 or enhanced.14,24”

    From Enhanced Automatic Action Imitation and Intact Imitation-Inhibition in Schizophrenia (2019) · cites this paper as [15]

    The Abstract and Conclusions report generally intact MNS-related activity in schizophrenia during action observation and execution, measured by EEG mu suppression. The Introduction describes mixed findings from other EEG studies, and the Conclusions report diminished activity in MEG/TMS studies and abnormalities in fMRI studies. The paper supports the broader point that findings differ, but its own intact finding comes from EEG, not imaging or TMS, and it does not establish every listed outcome for those methods.

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.
