Researchers have developed a high-tech support system that can keep a large mammalian brain from rapidly decomposing in the hours after death, enabling study of certain molecular and cellular functions.

Researchers have identified ketamine-induced brain-related changes that are responsible for maintaining the remission of behaviors related to depression in mice — findings that may help researchers develop interventions that promote lasting remission of depression in humans.

On April 11-13, 2019, approximately 1,500 scientists from many disciplines will attend the fifth annual Brain Research through Advancing Innovative Neurotechnologies (BRAIN)® Initiative Investigators Meeting in Washington, DC. This open meeting provides a forum for discussing scientific developments and potential new directions, and to identify areas for collaboration and research coordination.

Vikram Harshad Patel, M.B.B.S., Ph.D., whose research has been funded by the National Institute of Mental Health (NIMH), will receive the John Dirks Canada Gairdner Award for Global Health. This honor recognizes the world’s top scientists and their outstanding achievements in global health research. Dr. Patel will receive the award on October 24, 2019, in Toronto, Canada.

The recent deaths of two school shooting survivors has brought the topic of suicide into everyday conversations. It’s important to know some facts and to know what to do if you think someone might be at risk for self-harm.

FDA approval of the postpartum depression treatment brexanolone represents the final phase of a bench-to-bedside journey for this drug — a journey that began in the NIMH Intramural Research Program. NIMH experts are available to provide information on postpartum depression and the importance of, and the science underlying, this new drug.

Researchers have identified changes in brain connectivity and brain activity during rest and reward anticipation in children with anhedonia, a condition where people lose interest and pleasure in activities they used to enjoy.

A research team found nearly one-third of youth ages 10 to 12 years screened positive for suicide risk in emergency department settings, including those seeking help for physical concerns only.

Researchers have shown that a type of magnetic resonance imaging — called neuromelanin-sensitive MRI (NM-MRI) — is a potential biomarker for psychosis. NM-MRI signal was found to be a marker of dopamine function in people with schizophrenia and an indicator of the severity of psychotic symptoms in people with this mental illness.

Researchers have launched an ultra-large virtual docking library expected to grow to more than 1 billion molecules by next year. It will expand by 1000-fold the number of such “make-on-demand” compounds readily available to scientists for chemical biology and drug discovery.
