Functional deficits and correlations: Panels A and B show impairments of spatial learning spatial learning function and the olfactory learning and memory measured by the Morris water maze test (a) and odor recognition test (b) in rats after T2DM. Scatter plot graphs C and D show the correlation between the percentage areas with low molecular weight tracer TR-d3 measured 6 h after ICM injection and the water maze test scores (day 5, c), and odor recognition test scores (d) in DM and non-DM rats.
