...Siddharth Ramakrishnan; A. Don Murphy ABSTRACT Egg laying in pulmonate snails is a well-orchestrated process that involves a period of reduced locomotion, followed by substrate cleaning with rhythmic rasping of the surface to make tiny grooves, into which eggs are deposited. Although...

... and a selective PKG inhibitor, H-7 and KT-5823, respectively,reduced the frequency of the rhythm, suggesting that PKG acted as a target for cGMP. Thus, we conclude that NO plays a key role in regulating the frequency of the central pattern generator controlling rhythmic egg-laying movements in locusts by acting...

... is necessary for normal expression of the behaviour associated with egg deposition. Egg-laying behaviour for A. californica ( Arch & Smock, 1977 ) was initially described following injections of crude or purified bag cell extracts, and it still remains unclear which patterns of behaviour are produced...
