The spectral characteristics of shadow response in mature adults of Lymnaea stagnalis
Comparative research on spectral dependence between the appearance of shadow defensive reflex in intact and eyeless adults of Lymnaea stagnalis proved the excitatory role of dermal photoreception and the inhibitory role of the ocular one. The shape of the curve and the modified spectral maximum of the absorption of dermal light-sensitive ...
The Spectral Dependence of Skin Sensitivity to Light in Immature LYMNAEA STAGNALIS L. Specimens
By carrying out a quantitative evaluation of appearances of the shadow reflex, we obtained a spectral dependence of skin light sensitivity of immature specimens of Lymnaea stagnalis L. We performed experiments on juvenile specimens with a maximum shell size of 15 mm, to rule out the influence of the sexual dominant on the ...
