For decades, scientists have mapped attention, memory, language, and reasoning to separate brain networks — yet one big mystery remained: why does the mind feel like a single, unified system?

Impaired glymphatic function — the brain’s waste clearance system — could help explain how cardiovascular disease (CVD) risk factors may drive dementia. In a large UK Biobank study, MRI markers of ...

Johns Hopkins scientists say they have used 3D imaging, special microscopes and artificial intelligence (AI) programs to construct new maps of mouse brains showing a precise location of more than 10 ...

Aging compromises the lymphatic vessels surrounding the brain, disabling waste drainage from the brain and impacting cognitive function. Researchers boosted lymphatic vessel integrity in old mice and ...

Your brain ventricles are four fluid-filled chambers that produce cerebrospinal fluid. This fluid helps nourish your brain and protect it from injury. It would be easy to argue that your brain is the ...

Brain volume and function are altered in individuals with opioid use disorder, a new Yale study finds. Using magnetic resonance imaging (MRI) and functional MRI (fMRI), researchers observed the ...

Why do cats generally live longer than dogs? New research suggests that longer livespans of mammals like cats could be linked to their bigger brains and more complex immune systems. An international ...
