- Aggression-Related Gene Weakens Brain’s Impulse Control Circuits
- Press Release March 20, 2006
A version of a gene previously linked to impulsive violence appears to weaken brain circuits that regulate impulses, emotional memory and thinking in humans, researchers at NIMH have found.
- Gene Influences Antidepressant Response
- Press Release March 15, 2006
Whether depressed patients will respond to an antidepressant depends, in part, on which version of a gene they inherit, a study led by scientists at NIH has discovered. Having two copies of one version of a gene that codes for a component of the brain’s mood―regulating system increased the odds of a favorable response to an antidepressant by up to 18 percent, compared to having two copies of the other, more common version.
- Depression Model Leaves Mice with Molecular Scar
- Press Release February 27, 2006
In addition to triggering a depression-like social withdrawal syndrome, repeated defeat by dominant animals leaves a mouse with an enduring “molecular scar” in its brain that could help to explain why depression is so difficult to cure, suggest researchers funded by NIMH.
- Lithium Blocks Enzyme To Help Cells’ Clocks Keep On Tickin’
- Science Update February 17, 2006
NIMH-funded researchers have discovered how lithium likely fixes body clocks gone awry, stabilizing sleep-wake cycles and other daily rhythms disturbed along with mood in bipolar disorder.
- Mice Lacking Social Memory Molecule Take Bullying in Stride
- Press Release February 09, 2006
The social avoidance that normally develops when a mouse repeatedly experiences defeat by a dominant animal disappears when it lacks a gene for a memory molecule in a brain circuit for social learning, scientists funded by the National Institutes of Health's (NIH) National Institute of Mental Health (NIMH) have discovered.
- Nobelist Discovers Antidepressant Protein in Mouse Brain
- Press Release January 06, 2006
A protein that seems to be pivotal in lifting depression has been discovered by a Nobel Laureate researcher funded by NIMH.
- Trust-Building Hormone Short-Circuits Fear In Humans
- Press Release December 07, 2005
A brain chemical recently found to boost trust appears to work by reducing activity and weakening connections in fear-processing circuitry, a brain imaging study at the National Institutes of Health's (NIH) National Institute of Mental Health (NIMH) has discovered.
- Gene Knockout Scores a Fearless Mouse
- Press Release November 22, 2005
Knocking out a gene in the brain's fear hub creates mice unperturbed by situations that would normally trigger instinctive or learned fear responses, researchers funded, in part, by the National Institutes of Health have discovered.
- Teens with Deletion Syndrome Confirm Gene’s Role in Psychosis
- Press Release October 23, 2005
A study in youth who are missing part of a chromosome is further implicating a suspect gene in schizophrenia.
- NIH Joined by Advocacy Groups to Fund Research on Autism Susceptibility Genes
- Press Release October 18, 2005
Five institutes at the National Institutes of Health (NIH) and three private autism organizations have formed a consortium to pursue their common goal of understanding a devastating disorder.
- Scientists Uncover New Clues About Brain Function in Human Behavior
- Press Release July 10, 2005
Researchers at the National Institute of Mental Health (NIMH), part of the National Institutes of Health, have discovered a genetically controlled brain mechanism responsible for social behavior in humans — one of the most important but least understood aspects of human nature.
- NIH “Roadmap” Grants Will Establish Nine Screening Centers in Seven States
- Press Release June 15, 2005
The National Institutes of Health (NIH) today announced it is awarding $88.9 million in grants to nine institutions over three years to establish a collaborative research network that will use high-tech screening methods to identify small molecules that can be used as research tools.
- Rodent Social Behavior Encoded in Junk DNA
- Press Release June 09, 2005
A discovery that may someday help to explain human social behavior and disorders such as autism has been made in a species of pudgy rodents by researchers funded, in part, by the National Institutes of Health's (NIH) National Institute of Mental Health (NIMH) and National Center for Research Resources (NCRR).
- NIMH Research Showcased at APA Meeting
