Values are means ± SE; n=6. Administration of muscimol at the adjusted the adjusted ventilator rate were slightly lower than baseline values, however differences were not significant (P >0.05). Differences between values post muscimol and bicciucllinebicuculline were not Significant (P >0.05) for all analyzed variables.There were no significant differences (P > 0.05) between control and treatment values for all variables.
