The influence of aging effect on peripheral sensory function was investigated using BOLD fMRI and fcMRI on rats. Results shows the sensory network in the cortex peaks at adult age. At the same time, sensory network at senile age shows strongest inter-voxel correlation, which indicates a more optimized structure at this period.
