Regions of interest.

The prefrontal cortex (blue), caudate putamen (red), amygdala (purple) and the somatosensory cortex (yellow) of the left (L) and the right (R) hemisphere were delineated on the B0 images and the estimated diffusion parametric maps, referencing to a rat brain atlas [25].本研究参照大鼠脑图谱[25]，在B0图像（B0 images）与估算得到的扩散参数图（diffusion parametric maps）上，对左（L）、右（R）大脑半球的前额叶皮层（prefrontal cortex，蓝色）、尾状壳核（caudate putamen，红色）、杏仁核（amygdala，紫色）以及躯体感觉皮层（somatosensory cortex，黄色）进行了勾画。
