This Viewpoint reports on 3 neuroscientists who were recently awarded the 2014 Nobel Prize in Physiology or Medicine for their seminal research in understanding how 2 neighboring brain regions, the hippocampus and the entorhinal cortex, represent spatial information.
Several human degenerative diseases appear as a result of the misfolding and aggregation of proteins.1 The prototype central nervous system proteinopathy is Creutzfeldt-Jakob disease (CJD), in which neuronal prion protein (PrP) with high α-helical content switches into a stable structure rich in β-pleated sheets in a self-catalyzing process that eventually, ...
