Figure 8

Irregular wavepaths for contractions of the isolated ovary. Ai. Replicate measures of the position of the light/dark interface were made at three sites; the same colour is used for each site. For each site, three adjacent replicates were made and the signal averaged to reduce the noise. Aii. The resulting ovariogram shows that several kinds of contractions were observed, some as a single peak, others biphasic and some triphasic. Aiii. Overlaying the recordings so that waves are aligned at the tip shows that some waves move from tip to base, others from base to tip. This was observed in both the isolated ovary and the reproductive tract complete. B. Similar recordings from another preparation, showing consistent waves of contraction moving from tip to base and on into the oviduct. Scalebar: 250 μm.
