Investigation of sleep spindle activity and morphology as predictors of neurocognitive functioning in medicated patients with schizophrenia.

abstract：:An intermediate phenotype of a disease is a trait in the path of pathogenesis from genetic predisposition to disease manifestation. Identifying intermediate phenotypes with high heritability is helpful in delineating the genetics of a disorder. In this study, we aimed to examine various traits with regards to obesity,...
