From: Contribution of nitric oxide to cerebral blood flow regulation under hypoxia in rats
Change in normalized evoked CBF under normoxia and hypoxia without LNA. a Normalized evoked CBF with somatosensory stimulation from one representative animal. Curves were normalized to the baseline level. Horizontal and vertical bars indicate the stimulation period and 10% increase from the baseline level, respectively. b Peak amplitude of normalized evoked CBF under normoxia and hypoxia without LNA. Each line corresponds to the data obtained from one rat. Bold lines and error bars indicate the mean value and SD, respectively (n = 9). Note that the normalized evoked CBF was significantly higher during hypoxia than during normoxia (*P < 0.05)
