- Science Update August 02, 2007
NIMH-funded scientists have developed a new high-speed technique for imaging brain activity and used it to pinpoint a circuit signal in rats that may be at the crossroads of depression — a possible "final common pathway" where different causes of, and treatments for, the disorder appear to converge.
- Study Offers Glimpse of Molecules That Keep Memories Alive
- Science Update July 02, 2007
Working memory is a kind of temporary-storage system in the brain. Unlike long-term memory, it stores disposable information we must keep in mind only transiently, for tasks at hand. But how?
- Genetic Roots of Bipolar Disorder Revealed by First Genome-Wide Study of Illness
- Press Release May 08, 2007
The likelihood of developing bipolar disorder depends in part on the combined, small effects of variations in many different genes in the brain, none of which is powerful enough to cause the disease by itself, a new study shows.
- Cell Networking Keeps Brain’s Master Clock Ticking
- Science Update May 04, 2007
Each day, a master clock in the brain synchronizes the timing of lesser clocks in cells throughout the body to the rising and setting of the sun, regulating such daily rhythms as sleep, body temperature, eating, and activity. Scientists funded in part by the National Institute of Mental Health have now discovered that the secret to this master clock’s robust time-keeping ability lies in the unique way its cells work together.
- Cortex Area Thinner in Youth with Alzheimer’s-Related Gene
- Press Release April 24, 2007
A part of the brain first affected by Alzheimer’s disease is thinner in youth with a risk gene for the disorder, a brain imaging study by researchers at the National Institute of Mental Health (NIMH), one of the National Institutes of Health (NIH), has found.
- Gene Knockout Unleashes Manic Mouse
- Science Update April 05, 2007
Mice engineered to lack a specific gene showed behaviors similar to human mania in a study funded in part by NIMH; they were hyperactive, slept less, appeared less depressed and anxious, and craved sugar, cocaine and pleasure stimulation.
- Scientists Switch Neurons On and Off Using Light
- Science Update April 05, 2007
Researchers have invented a genetically-engineered way to turn the electrical impulses of brain cells on and off with pulses of blue and yellow light — in synch with the split-second pace of real time neuronal activity.
- Adolescent Brains Show Lower Activity in Areas That Control Risky Choices
- Science Update March 15, 2007
A new NIMH study could help explain why adolescents are so prone to make risky choices. When contemplating risky decisions, they show less activity in regions of the brain that regulate processes involved in decision-making, compared with adults.
- Tiny, Spontaneous Gene Mutations May Boost Autism Risk
- Press Release March 15, 2007
Tiny gene mutations, each individually rare, pose more risk for autism than had been previously thought, suggests a study funded in part by the National Institute of Mental Health, a component of the National Institutes of Health.
- Virtual-Reality Video Game Helps Link Depression to Specific Brain Area
- Science Update March 01, 2007
Scientists are using a virtual-reality, three-dimensional video game that challenges spatial memory as a new tool for assessing the link between depression and the hippocampus, the brain’s memory hub.
- Largest-Ever Search for Autism Genes Reveals New Clues
- Press Release February 18, 2007
The largest search for autism genes to date, funded in part by the National Institutes of Health (NIH), has implicated components of the brain’s glutamate chemical messenger system and a previously overlooked site on chromosome 11.
- Common Gene Version Optimizes Thinking — but With a Possible Downside
- Press Release February 09, 2007
Most people inherit a version of a gene that optimizes their brain’s thinking circuitry, yet also appears to increase risk for schizophrenia, a severe mental illness marked by impaired thinking, scientists at the National Institutes of Health’s (NIH) National Institute of Mental Health (NIMH) have discovered.
- Autism Research Efforts Highlighted in Biological Psychiatry Special Issue
- Science Update February 06, 2007
The February 15, 2007 special issue of Biological Psychiatry is dedicated to recent advances in autism research, including many studies funded by the Institute.
- Brain’s Reward Circuit Activity Ebbs and Flows with a Woman’s Hormonal Cycle
- Press Release February 02, 2007
Fluctuations in sex hormone levels during women’s menstrual cycles affect the responsiveness of their brains’ reward circuitry, an imaging study at the National Institute of Mental Health (NIMH) has revealed.
- New Tests May Help Researchers Detect Genetic Basis For Autism
- Science Update January 30, 2007
Researchers have developed a set of behavioral tests in mice that mimic the core features of autism and may prove useful in detecting a genetic basis for the deficits in social interactions and rigid thinking seen in the disorder.
- Clues to Making and Breaking Memories Included in List of Year’s Top Science
- Science Update January 30, 2007

It’s long been known that experiencing control over a stressor immunizes a rat from developing a depression-like syndrome when it later encounters stressors that it can’t control.
- Receptor Helps Neurons Grow in Right Direction
- Science Update December 12, 2006
Researchers have discovered a receptor for a key protein that helps guide certain nerve cells into the correct position as the nervous system develops — a vital part of a process that enables the brain to receive sensory input from the environment and to send messages to the rest of the body via the spinal cord.
- Broad HIV Screening Valuable Even in Communities with Low Infection Rates
- Science Update December 05, 2006
An HIV/AIDS screening program may be cost-effective even in communities where the infection rate and the prevalence of the disease are very low and among populations at low risk for HIV infection, according to an NIMH-funded study published December 5, 2006, in the Annals of Internal Medicine.
