Effect of intranasally administered insulin on cerebral blood flow and perfusion; a randomized experiment in young and older adults

Figure 3. Paired individual gray matter perfusion measurements for placebo and insulin conditions. Left panel represents the gray matter perfusion in the parietal lobe as paired data for placebo and intranasal insulin per individual subject in the young and the older group. The right panel represents the gray matter perfusion in the occipital lobe.
