When we form a new memory, the brain undergoes physical and functional changes known collectively as a "memory trace." A memory trace represents the specific patterns of activity and structural ...

Novel research presented at the 41st annual meeting of the European Society of Human Reproduction and Embryology (ESHRE) has found that embryos from women with PCOS carry a distinctive "epigenetic ...

When a new memory forms the brain undergoes physical and functional changes known collectively as a “memory trace.” This memory trace represents the specific patterns of neuronal activity and ...

When cells are healthy, we don't expect them to suddenly change cell types. A skin cell on your hand won't naturally morph into a brain cell, and vice versa. That's thanks to epigenetic memory, which ...

Our experiences leave traces in the brain, stored in small groups of cells called "engrams". Engrams are thought to hold the information of a memory and are reactivated when we remember, which makes ...

Neuroinflammation, a prolonged activation of the brain's immune system prompted by infections or other factors, has been linked to the disruption of normal mental functions. Past studies, for instance ...

An international research team led by the Helmholtz Center for Infection Research (HZI) has discovered a new strategy used by the human pathogen Pseudomonas aeruginosa to adapt to its host. In the ...

If parent cells and their daughter cells are to share a stable identity, parent cells must divide—and replicate their DNA—while ensuring that their histones are distributed properly to their daughter ...

In an important study for understanding how memories are made, cientists show that the flexibility of chromatin -- packaged DNA inside the cell -- plays a crucial role in 'deciding' which neurons are ...

Neurons have variable levels of chromatin compaction, shown as different shades of red. The less compact a neuron, the more likely it is to be recruited into the memory trace (green). When we form a ...
