Brain Region Singled Out for Social Memory, Possible Therapeutic Target for Select Brain Disorders

Science Update

highlighted CA2 region of hippocampus in mouse brain

The hippocampus houses learning and memory—specifically the storage of knowledge of who, what, where, and when. Using a special transgenic mouse, researchers have now pinpointed a hippocampal region called CA2 that is important for social memory, the ability of animal to recognize another of the same species. Understanding this region could be useful in understanding and treating disorders characterized by altered social behaviors such as schizophrenia, bipolar disorder, and autism.

Bullying Exerts Psychiatric Effects Into Adulthood

Once considered a childhood rite of passage, bullying lingers well into adulthood. Bullies and victims alike are at risk for psychiatric problems such as anxiety, depression, substance abuse, and suicide when they become adults, reported a study partially funded by the National Institute of Mental Health (NIMH) that was published in the April issue of JAMA Psychiatry.

Ketamine Cousin Rapidly Lifts Depression Without Side Effects

Science Update

GLX-13 Thumbnail

NMDA or glutamate receptor modulators as antidepressants have come of age. Human clinical studies demonstrated that ketamine can ward off depressive symptoms within 2 hours of administration and last for several days. Yet serious side effects are attached to this drug, including excessive sleepiness, hallucinations, and substance abuse behavior.

Taming Suspect Gene Reverses Schizophrenia-like Abnormalities in Mice

Press Release

Neuregulin 1

Scientists have reversed behavioral and brain abnormalities in adult mice that resemble some features of schizophrenia, by restoring normal expression to the gene Neuregulin1, which makes a protein important for brain development.
