Reactivating a specific memory circuit in mice

Findings could spur new ways to study and treat human memory loss.

In a new study, Neuroscientists at Johns Hopkins Medicine successfully used a sophisticated brain-imaging system to reactivate a specific memory circuit in mice. This lets the mice find shelter even if no shelter is present.

The study sheds light on how memories are structured in the mammalian brain. It could lead to new ways of slowing down or preventing the memory loss that accompanies Alzheimer’s and other neurodegenerative diseases.
