Fig. 10. CE exposure and RPeD1 activity in semi-intact preparations. (A) Representative electrophysiological recordings from RPeD1 in semi-intact preparations taken after intact snails were exposed to PW (top), CE (middle) or BC (bottom) treatments. All traces demonstrate spontaneous firing activity, and bursting activity. (B) Summary data for mean (±s.e.m.) spiking activity per 10 min (square-root transformed, N=14). Results for CE were significantly lower (^**P<0.001, N=14) than those for either PW or BC, which were not significantly different from each other. (C) Mean (±s.e.m.) number of spikes per burst. Again, results for CE were significantly lower (^**P<0.001, N=14) than those for either PW or BC, which were not significantly different from each other (from Orr et al., 2007).
