Epigenetics contribute to male and female differences in fear memory

In a mouse model of traumatic memory, male mice recall fear-related memories better than female mice, according to a study in Biological Psychiatry. The difference between sexes was attributed to a gene important for creating ...

An immunological memory in the brain

Inflammatory reactions can change the brain's immune cells in the long term—meaning that these cells have an "immunological memory." This memory may influence the progression of neurological disorders that occur later in ...

How obesity makes memory go bad

University of Alabama at Birmingham researchers are probing how obesity makes memory goes bad, and the underlying molecular mechanism that drives this decline.

New insights into the molecular basis of memory

Scientists from the German Center for Neurodegenerative Diseases have shed new light on the molecular basis of memory. Their study confirms that the formation of memories is accompanied by an altered activity of specific ...

Master switch for brain development found

Scientists at the Institute of Molecular Biology (IMB) in Mainz have unraveled a complex regulatory mechanism that explains how a single gene can drive the formation of brain cells. The research, published in The EMBO Journal, ...

Evolutionarily preserved mechanism governs use of genes

Researchers at Uppsala University have found that the protein coding parts of a gene are packed in special nucleosomes. The same type of packaging is found in the roundworm C elegans, which is a primeval relative of humans. ...
