Our 6-yr efforts is finally published on Nature Communications! We discover a neural pathway that regulates the glymphatic system. Its deficit in aging and dementia may result in the pathology. This suggests new targets for diagnosis and treatment. nature.com/articles/s4146…

What do you see when you stare at this grid of line segments: a series of rectangles, or a series of circles? The way you perceive this optical illusion may tie back to the visual environment that surrounds you, a recent preprint suggests. scim.ag/40e6PCU

Does mental stress affect our mitochondria? In this new paper, we asked if 5 minutes of mental stress (public speaking) changed the amount of cell-free mitochondrial DNA (cf-mtDNA) Absolute saliva cf-mtDNA levels increased on average by 280% after mental stress! 🧵

If you don’t have time to take a walk, then you don’t have time to do science. Charles Darwin would take two walks every day on his "thinking path", not as a break from science, but as a crucial part of it.

This study observed small but important differences in rates of AD, up to 20% greater incidence in several regions compared with the Mid-Atlantic. How to use this data to devise strategies that mitigate the impact of dementia on vulnerable populations?jamanetwork.com/journals/jaman…

Very excited to share the results of this collaborative work in young adults with spina bifida. APOE4 carriers showed smaller left amygdala volumes —suggesting early neurodegeneration risk. Can MRI help identify vulnerable SB subgroups? #APOE4 #MRI doi.org/10.1002/cns3.7…
