Fig. 5. Representative electrophysiological recordings from RPeD1 in semi-intact preparations taken from wild Dutch and laboratory snails before (naive) and 24 h after operant conditioning. No significant differences were found between any of the measured electrophysiological characteristics (wild Dutch naive, N=8; wild Dutch 24 h, N=8; laboratory-reared Dutch naive, N=9; laboratory-reared Dutch 24 h, N=8).
