Suppression of egg-laying during starvation in the snail Lymnaea stagnalis by inhibition of the ovulation hormone producing caudo-dorsal cells.

Abstract:

:Starvation inhibits egg-laying in the snail, Lymnaea stagnalis. In starved animals the neurosecretory Caudo-Dorsal Cells (CDC), which produce the egg-laying hormone, are hyperpolarized as compared to the CDC of controls. However, they are more responsive to repetitive intracellular stimulation, which induces the hormone releasing discharge. Hyperpolarization is not found in the non-neurosecretory Cerebral Giant Cells, which indicates that the effect is specific for the CDC. It is also a characteristic effect of starvation as compared to another treatment (dirty water) inhibiting egg-laying.
