Neural metabolic activity was increased in the auditory-associated areas of rats with cerebral venous congestion. a Representative coronal or transaxial microPET images of JVL rats at 0 d/14 d/3 M postoperatively. Dotted areas identify AMY, ACx, MGB, and IC regions at the corresponding level. PET images are displayed according to an identical color scale; values ranging from 0 to 5 indicate the elevation of 18 F-FDG uptake. All rats were imaged in the prone position. Sup, superior; Inf, inferior; Post, posterior; Ant, anterior; L, left; R, right; C: coronal; T: transaxial. b-e Standard uptake value ratio of 18 F-FDG in the AMY (b), ACx (c), MGB (d), and IC (e). All data are presented as the mean ± SD (two-tailed unpaired Student’s t test) and are representative of at least five independent experiments. Dots depict individual samples. ***p < 0.001 compared to the 0 d group
