Figure 1From: Turnover rate of cerebrospinal fluid in female sheep: changes related to different light-dark cyclesPlots of IVP recorded before and after removal of CSF in adult sheep, from the lowest pressure recorded arbitrarily set to zero for homogeneity (means Ā± SEM, n = 5). Recordings were made during short-day stimulated reproductive status (SG1 and SG2), and long-day inhibited reproductive status (IG). Note the lower slope for recovery during IG than during SG1 and SG2 (interaction between time and IVP, ANOVA: p < 0.005, SG1 different from IG, p < 0.05).Back to article page
