- Studies ID Molecular Accomplices of Suspect Schizophrenia Genes
-

•
Science Update
NIMH-funded researchers have discovered how certain genes work at the molecular level to increase the risk of schizophrenia.
- Properly Timed Light, Melatonin Lift Winter Depression by Syncing Rhythms
-
May 1, 2006
•
Science Update
Most Seasonal Affective Disorder (SAD) symptoms stem from daily body rhythms that have gone out-of-sync with the sun, a NIMH-funded study has found.
- Cortex Matures Faster in Youth with Highest IQ
-
March 29, 2006
•
Press Release
Youth with superior IQ are distinguished by how fast the thinking part of their brains thickens and thins as they grow up, researchers at NIMH have discovered.
- Aggression-Related Gene Weakens Brain’s Impulse Control Circuits
-
March 20, 2006
•
Press Release
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
-
March 15, 2006
•
Press Release
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
-
February 27, 2006
•
Press Release
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’
-
February 17, 2006
•
Science Update
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
-
February 9, 2006
•
Press Release
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 NIMH have discovered.
- Nobelist Discovers Antidepressant Protein in Mouse Brain
-
January 6, 2006
•
Press Release
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
-
December 7, 2005
•
Press Release
A brain chemical recently found to boost trust appears to work by reducing activity and weakening connections in fear-processing circuitry.
