Cortical inhibition in symptomatic and remitted mania compared to healthy subjects: A cross-sectional study.

Lower motor thresholds in remitted FEM perhaps reflect the effect of treatment, and could be studied as potential prognostic neuromarkers. Inverse findings for SICI (reduced) and LICI (increased) in BD indicate a possible differential involvement of the GABAA and GABAB subreceptor systems. These could be trait markers as they are impaired in both mania and euthymia.
