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 ...

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 ...

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 ...

This week, we reported on new epigenetic findings in memory formation as well as a dramatic spike in micromobility-related head injuries, so there's a whole lot of head-related science on the front ...

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 ...
