| Abstract: | Dopamine inhibits 5-hydroxytryptamine-stimulated maturation of the ovaries of the red swamp crayfish,Procambarus clarkii, in vitro just as it does in vivo. This in vitro inhibition appears to be due to inhibition of release of the gonad-stimulating hormone from the brain and thoracic ganglia. However, it is possible that in vivo dopamine also triggers release of the gonad-inhibiting hormone. |
