Figure 6


Fig. 6. RPeD1 activity in wild Belly snails following the single 0.5 h training session. (A) Representative recordings from RPeD1 in wild Belly snails starting at top with a naive snail (naive wild Belly), 24 h after the operant conditioning procedure, 72 h after conditioning, 72 h yoked control and 1 week after conditioning. (B) Summary data for mean (+s.e.m.) spiking activity per 600 s. (C) Number of spikes per burst. (D) Burst duration. (E) Number of bursts per 600 s. In all measured characters presented here, both the 24 h and 72 h operantly conditioned groups demonstrated significantly lower activity than the naive state and are significantly lower than the 72 h yoke and 1 week groups. 72 h yoke and 1 week groups are not significantly different from the naive state. All data represent log-transformed values. *P<0.05; **P<0.001. Naive N=9; 24 h N=9; 72 h N=7; 72 h yoke N=7; and 1 week N=8. No significant differences were detected between treatments in other electrophysiological parameters measured (see Materials and methods).
