In a landmark collaboration across 22 labs, neuroscientists have created the first brain-wide map of decision-making in mice, tracking over 620,000 neurons across nearly 280 brain regions. They found that decision-making is distributed much more broadly than previously thought, involving not just “cognitive” centers but also regions linked to movement. Read more…
Fine-particulate air pollution can drive devastating forms of dementia by triggering the formation of toxic clumps of protein that destroy nerve cells as they spread through the brain, research suggests. Exposure to the airborne particles causes proteins in the brain to misfold into the clumps, which are hallmarks of Lewy Read more…
