title: Inhibition of temperature-induced spermatogenic proliferation by a brain factor in hibernating Helix aspersa (Mollusca).
abstract: Ablation of the brain from hibernating Helix aspersa maintained at 25 degrees C causes a significant increase in the proliferation of male cells in the gonad, whereas the ablation of the optic tentacles has no effect. The brain, therefore, produces a factor which specifically inhibits the multiplication of spermatogonia and spermatocytes.
