FIGURE 2.

Mean CBF maps from a randomized, controlled crossover study in older adults (n = 23) after nonlinear co-registration to the Montreal Neurological Institute template, after soy nut intake (A) and the control period (B). The images show the CBF in mL · 100 g tissue⁻¹ · min⁻¹ (scale shown by color bar). No differences were observed between periods in global CBF (P = 0.567), gray matter CBF (P = 0.593), and CBF in the left (P = 0.570) and right (P = 0.542) hemispheres. CBF, cerebral blood flow.
