Summary

Cognitive deficit is a core symptom of schizophrenia (SZ), but its pathological mechanism is poorly understood and the treatment effect is poor. The excitatory-inhibitory microcircuit (E-I) function imbalance formed by inhibitory interneurons and excitatory pyramidal cells in the cerebral cortex is a new mechanism of cognitive deficits in SZ discovered in recent years. Cortical E-I is expected to be a new target for the treatment of cognitive deficits in SZ. Paired transcranial magnetic stimulation (ppTMS)-induced intracortical inhibition (ICI) is dependent on cortical E-I functional integrity. We found that ICI deficiency is stable in SZ and is closely related to cognitive function. Therefore, ICI is likely to be a system-level biomarker for cognitive deficits caused by E-I imbalance. However, no study has yet explored the genetic basis of ICI and its impact on the occurrence, development and treatment response of cognitive deficits in SZ. Based on this, we intend to verify the value of ppTMS-induced ICI as a biomarker of E-I imbalance in SZ patients and normal controls at different stages: 1. To explore the correlation of ICI with multidimensional cognitive deficits and E-I pathway genes; 2. To explore ICI Combining candidate genes and serum inflammatory factors can predict whether TMS can improve the efficacy of cognitive deficits, and can be used for precise treatment of SZ cognitive deficits at the level of pathological mechanisms.
