    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.

    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.
