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.

This study has shed light on the neurocomputational contributions to the development of post-traumatic stress disorder in combat veterans, finding distinct patterns for how the brain and body respond to learning danger and safety depending on the severity of PTSD symptoms.

A lineage of young neuroscientists from diverse backgrounds trace their scientific roots to a “fear lab” in Puerto Rico that the National Institutes of Health has been supporting for two decades.

A new study in rodents has demonstrated, for the first time, that the brain’s cerebellum plays a role in controlling reward and social preference behavior—findings that shed light on the brain circuits critical to the affective and social dysfunction seen across multiple psychiatric disorders.

The National Institute of Mental Health (NIMH) announces the addition of the new Sensorimotor domain to the Research Domain Criteria (RDoC) framework. The aim of the new domain is to help foster earlier and more precise identification of the role of motor systems disruptions in psychopathology and aid in the development of more effective treatments for people who are affected with these disruptions.

PsychENCODE researchers are discovering the biological mechanisms by which mental illness risk genes work in the human brain.

A new report provides guidance on how to implement universal suicide risk screening of youth in medical settings. The report describes a way for hospitals to address the rising suicide rate in a way that is flexible and mindful of limited resources.
