Abstract
Electrical stimulation of the archistriatum and paleostriatum primitivum leads to a 2- to 4-hr delay of ovulation and generally to a delay of 2–48 hr of oviposition in White Leghorn hens. The optimal time for stimulation for obtaining these effects is 13–16 hr before ovulation. Electrical stimulation of the neostriatum, area septalis, or of the paleostriatum augmentatum affects neither ovulation nor oviposition. Possible explanations are offered for the effects observed.
