TPSFs from a mouse brain in vivo. (A) The normocapnic TPSF with resolved static and dynamic components, determined from the autocorrelation (example at τs = 35 ps in inset). The static component is significant for short TOFs only, suggesting more superficial paths. For brevity, the superscript (iNIRS) was omitted in the inset. (B) The asymptotic slope of the hypercapnic dynamic TPSF is larger than the normocapnic one due to increased absorption during hypercapnia (Fig. 3).
