FIGURE 3. Metabolic variances of aged conscious monkey brains. Images were created from calculation of coefficient of variation (COV) at each pixel in 3-dimensional SSP format across 5 monkeys. Top row shows right lateral (RT.LAT), left lateral (LT.LAT), and superior (SUP) aspects of brain, and bottom row represents right medial (RT.MED), left medial (LT.MED), and posterior (POST) aspects of brain. Highest metabolic variance is seen bilaterally in region of central sulcus.
