请教DMN及其负相关网络的区别

各位老师好：
我在贵实验室Wu, J.T., et al., Aging-related changes in the default mode network and its anti-correlated networks: A resting-state fMRI study. Neuroscience letters, 2011.的文章上看到采用小球法提出四个区域：PCC+、PCC-、vmPFC+、vmPFC-。将这四个区域取并集后构成的Mask，称之为默认网络及其负相关网络(default mode network and its anti-correlated networks)。根据这个说法，我想请问：
1. 单纯的默认网络DMN区域，是否仅为上述PCC+和vmPFC+的并集
