Photoinactivation of neurones in the pond snail, Lymnaea stagnalis: estimation of a safety factor.
Neurones were irradiated with blue laser light (440 nm). The intensity of light for reliable cell killing (0.5 MW.m-2) was much greater than that used to kill arthropod neurones. In wild snails, there was no difference in the intensity to kill Lucifer yellow-filled neurones and unfilled neurones, probably because of the red pigments in the cell bodies. In laboratory-reared snails, which have much less pigmentation, only the filled cells were killed.
