Sleep deprivation increases the number of available A1 adenosine receptors, but restorative sleep helps normalize them again, a new study reports.
Researchers propose a new approach to neuroimaging studies. They suggest, rather than beginning with predefined behavioral functions and trying to assign associated brain regions, new studies should focus on selecting brain areas first and screen for potential behavioral associations.
Researchers have captured some of the sharpest images of Alzheimer's associated amyloid fibrils to date. The 3D structure of the fibrils displays some previously unknown structural details that researchers believe could help answer some important questions about the development of Alzheimer's disease.
