The effect of limiting light to the pineal on the rate of forelimb regeneration in the newt.
Newts with bilaterally amputated forelimbs were exposed to either continuous light (LL), total darkness (DD), or continuous light with the dorsal head epithelium painted with an India ink and Nile blue sulfate mixture (LL-II-NBS) that limited light penetration through the skull to the pineal. The LL-II-NBS animals regenerated their forelimbs more slowly then their counterparts in LL.
