The autocorrelation of the fMRI signal is affected by ongoing brain cognitive processes and can provide complementary information about the brain function.
Figure 1. F-map of the task effect. AC values are significantly different during different cognitive tasks in the majority of the gray-matter cortex.
Figure 2. Paired comparison of the AC patterns between the tasks. Cognitively demanding tasks like working memory and mathematical computations significantly reduces the AC values in the brain regions associated with those tasks.
