A neuroscience study found that brain activity in the caudate region is strongly linked to grip strength in older adults, potentially offering new ways to diagnose and prevent age-related frailty.

A Frontiers in Neuroscience study led by Professor Xiaoping Hu and first author Amin Ghaffari found that MRI scans of older adults revealed the caudate nucleus, a little-known brain region near the thalamus involved in working memory and executive functioning, showed unusually strong correlation with grip strength through analysis of the brain's functional connectome.
