Effects of A
R activation on individual inspiration-related preBötC neurons. A. NCPA (1 μM) decreased Rin of synaptically isolated neurons (n = 7; * P < 0.05). B. In this representative pair of whole cell current traces evoked by a voltage step from -60 to 20 mV IKd is similar during recording in normal aCSF (black trace) and in NCPA (grey trace). Vertical scale: 100 pA; time scale: 50 ms. C. Mean current-voltage relationship for inspiratory neurons (n = 5; error bars represent SEM).
