Two new studies show that the brain’s navigation system changes how it represents physical space to reflect personal experience.
Researchers find that when working memory gets overburdened, dialogue between three brain regions breaks down. The discovery provides new support for a larger concept about how the brain works.
Stimulating part of the cortex as needed during learning tasks improves later recall. The finding reveals more about the brain’s memory network and points toward possible therapies.
Nobel laureate Susumu Tonegawa’s lab is overturning old assumptions about how memories form, how recall works and whether lost memories might be restored from “silent engrams.”
