![]() Averaged BOLD time courses obtained at 40-ms temporal resolution from all nine animals used in this study. Layers IV-V present the fastest onset time to stimulation, followed by layers I-III and VI. Vertical bars = 1 standard error. The inset clearly shows the difference in onset times (error bars omitted for clarity). Afonso C.
