Summary: Rejuvenating the brain’s lymphatic vessels can enhance memory in aging mice by improving the removal of waste products from the brain. This research suggests that targeting the meningeal lymphatics—vessels outside the brain—could be a novel approach to treating age-related cognitive decline without directly crossing the blood-brain barrier.The treatment reduced...
Summary: A new study shows that our brains physically link memories formed close together in time through changes in the dendrites of neurons, rather than in the cell bodies. Using advanced imaging in mice, researchers found that the same dendritic branches are activated when closely timed experiences are encoded, effectively...
Summary: Fruit flies with genetic mutations that severely reduce sleep show enhanced performance in olfactory memory tasks, challenging assumptions about sleep’s role in cognition. This paradox appears to be driven by increased protein kinase A (PKA) signaling in the mushroom body, a brain region responsible for memory and sleep regulation....
