Cortical sensory aging is layer-specific

We employed a unique approach and acquired layer-specific structural and functional magnetic resonance imaging (fMRI) data using 7T-MRI of the 2 (which was not certified by peer review) is the author/funder.

The subject of this preprint is the primary somatosensory cortex (SI) of healthy younger and older adults together with behavioral assessments. We also investigated an individual with unilateral congenital arm loss to test for the effect of reduced sensory input on the SI layer architecture.
