Amyloid plaques are a hallmark of some neurodegenerative diseases like Alzheimer’s or Parkinson’s. Even though the exact role of amyloid protein in the disease is not clear, being able to follow amyloid protein misfolding and plaque formation could be a step forward for the study of the disease. Now, Matthew Lew’s lab has developed a […]
Think nothing. Your brain is always on, as your heart, liver or kidneys are, so thinking nothing is the closer you’ll get to a resting state for it, because even when we sleep the brain is quite active. We know that the interactions among different brain regions can be studied with functional magnetic resonance imaging […]
