Working under the umbrella of the PsychENCODE Consortium, the mental health research project established in 2015 by the National Institutes of Health, a team of Mount Sinai scientists has uncovered important new insights into the molecular biology of neuropsychiatric disease through two new studies published in a special issue of Science on Friday, May 24. These investigations, conducted with colleagues from other major research centers, involve the largest single-cell analysis to date of the brains of people with schizophrenia, and a first-of-its-kind population-scale map of the regulatory components of the brain that provides critical insights into the pathogenesis of mental health disorders.
