Fig. 1

shows the ReHo differences between colorectal cancer survivors (n = 18) and healthy controls (n = 17). Survivors exhibited significantly increased ReHo in the left HIP, PHG, and ITG, along with significantly decreased ReHo in the left IFGtri and left postcentral gyrus. Detailed information regarding these regions is provided in Table 5 (corrected p < 0.05).
