μ-Opioid agonists continue to inhibit ICa in trigeminal ganglion sensory neurons from CMT mice. ICa was evoked by repetitively stepping TG neurons from −90 to 0 mV. Time plots of the ICa amplitude of TG neurons taken from vehicle-treated mice illustrate the effect of application of several morphine (a) and DAMGO (b) concentrations on ICa. These can be compared with responses of TG neurons from CMT mice to morphine (c) and DAMGO (d). In all experiments, drugs were applied for the duration of the bars. Example traces from each experiment are reproduced below the respective time plots.
