Your Brain Expands and Shrinks Over Time – These Charts Show How
Based on more than 120,000 brain scans, the charts are still preliminary. But researchers hope they could one day be used as a routine clinical tool by physicians.

Sobre o que é?
A large-scale study of MRI scans shows how the human brain expands and shrinks over a lifetime.
Recommendation
A significant new study shows that the human brain expands in childhood, and shrinks as people age, reports Max Kozlov in Nature. Although considered a work in progress, the collection of more than 120,000 MRI scans reveals remarkable clarity in important aspects of human brain structure. Issues of expense and access have previously prevented the compilation and assessment of such a large group of brain images, which provide illuminating data on brain development, and may eventually contribute to studies of brain abnormalities and disease.
