  • Values are means ± SE. Numbers in parentheses indicate the number of motoneurons sampled. AHP, afterhyperpolarization.

  • *  These measurements were made during atonia following the injection of 0.25 μl of a solution of bicuculline (10 mM in saline) into the nucleus pontis oralis;

  • P < 0.05;

  • P < 0.01.
