Research Highlights about Basic Research
- Genomic Data From More Than 41,000 People Shed New Light on Bipolar Disorder
In the largest genome-wide association study of bipolar disorder to date, researchers found about twice as many genetic locations associated with bipolar disorder as reported in previous studies. These and other findings help improve our understanding of the biological origins of bipolar disorder.
- Mapping ‘Imbalance’ in Brain Anatomy Across the Lifespan
Researchers in the NIMH Intramural Research Program have developed a new way to measure the degree to which the proportions of an individual person’s brain differ from the proportions typically seen in the broader population. This technique yields new insights into brain development and offers tools for further study.
- Genetic Variations Highlight the Importance of Metabolic Processes in Anorexia
The need to identify effective targets for intervention in anorexia nervosa is pressing, as patient outcomes are often poor. An NIMH-funded genome-wide association study suggests that metabolic processes may play an important role in the disorder, offering a promising new avenue for investigation.
- Brain Processes Underlying the Extinction and Reactivation of Fear Memories
In a study published in 2019 in the journal Nature Neuroscience, researchers funded by the National Institute of Mental Health investigated the neurobiological changes that occur in the brain circuits of mice when contextual fear memories — fear of a place where an aversive event occurred — are formed and extinguished.
- Large-Scale Genetics Study Sheds Light on Developmental Origins of Autism
Researchers were able to identify different types of rare genetic variations associated with autism spectrum disorder by analyzing data shared via the NIMH-funded Autism Sequencing Consortium.
