Fig 3.
(A) Left, mean +/− SEM Ca2+ responses of vagal neurons that responded to the Ca2+ addback following thapsigargin (1 μM, green, n=32 out of 108) or following thapsigargin (10 μM) in the absence (black, n=121 out of 310) or presence of SKF96365 (SKF, 10 μM, red, n=35 out of 102); right, proportion of vagal neurons responding to the Ca2+ addback. (B) Left, mean +/− SEM Ca2+ responses of vagal neurons that responded to the Ca2+ addback following caffeine (10 mM) under control conditions (black, n=55 out of 233) or in the presence of SKF96365 (10 μM, red, n=13 out of 33) or Gd3+ (10 μM, green, n=5 out of 117). Blocked line denotes the 60-s application of drugs. All neurons responded to KCl (75mM) applied immediately before ionomycin.
