Abstract excerpt
Substantial evidence implicates the phosphoinositide cascade in invertebrate phototransduction, but the final pathway of excitation remains obscure. In order to test the hypothesis that Ca2+ is the excitatory messenger rapid concentration jumps of cytosolic Ca2+ were achieved in dissociated Droso...
