Fig. 5. Effects of bicuculline and strychnine on halothane depression of nonnoxiously evoked activity are shown. (A ) Bicuculline significantly but only partially reversed the halothane depression of the mean responses. (B ) Strychnine also only partially reversed the halothane depression of receptive field (RF) size and response to 41°C stimulation. The strychnine effects on brush response are considered to be nonspecific to halothane. Data are presented as mean ± SD. *P < 0.05 versus control and #P < 0.05 versus bicuculline or strychnine, 0 mg/kg, with halothane. C = control; Re = recovery; n = 9–11.
