Figure 2. Mean levels of tSNA are elevated in neonatal SH rats.
A, mean (±s.e.m.) integrated level of thoracic sympathetic nerve activity (∫tSNA) in each age group of SH and WKY rats. A significantly higher level was observed in the neonatal SH rats compared to age-matched WKY rats, but no significant difference between SH and WKY rats at 3 and 5 weeks old. (*P < 0.05 compared to WKY (2-way ANOVA), n= 5 per group). B and C, traces of raw and integrated (∫tSNA; Tc 100 ms) tSNA and perfusion pressure (PP) in neonate WKY (B) and SH rat (C).
