Effects of repetitive applications of excitatory modulators on carotid body sensory activity. A: carotid body sensory responses to repetitive applications (5 times for 30 s each at 5-min intervals at arrows) of ACh (10 μM), ATP (100 μM), substance P (SP, 1 μM), and KCl (40 mM). Insets: superimposed action potentials of a single fiber from which data were derived. White line represents baseline activity. B: average data of the sensory long-term facilitation (LTF; sensory activity averaged over the entire 60 min of the postapplication period). Values are means ± SE; n = 13 for ACh and ATP, n = 12 for SP, and n = 11 for KCl. NS, P > 0.05 compared with prestimulation baseline activity.
