Peak-normalized laminar BOLD, T2*, and S0 time-courses. For laminar BOLD time-courses, the fastest onset times appeared in L3–L4, followed by L1+2, L5, and L6. For laminar T2* time-courses, the ranking from BOLD was somewhat preserved besides L1+2, which was highly fluctuated. At L1+2, the onset time became obvious only when unfiltered time-courses were fitted with HRF of three gamma density functions. For laminar S0 time-courses, only L1+2 was shown and analysis for onset time, because S0 changes were only significant at L1+2.
