Your Brain Is Bigger In The Morning

The brain shrinks over the course of the day, ending up smaller in the evening – before returning to its full size the next morning. That’s according to a neat new study based on an analysis of almost 10,000 MRI scans. It’s published today in Neuroimage.

Kunio Nakamura and colleagues of the Montreal Neurological Institute examined 3,269 scans from multiple sclerosis trials and 6,114 from the ADNI Alzheimer’s disease project. This makes it the biggest neuroscience study I can think of.
