Spectra of absorption optic signals of invertebrate neurons stained with voltage sensitive dyes



Spectra of absorption optic signals of invertebrate neurons stained with voltage sensitive dyes



Doklady Akademii Nauk SSSR 286(6): 1512-1516



Absorption optical signals stained with voltage-sensitive dyes were studied in the following invertebrate species from various systematic groups: Planorbis corneus, Lymnaea stagnalis, Hirudo medicinalis, Periplaneta americana, Gryllus bimaculatus and G. campestris. The 3-phase spectrum of optical signals of the voltage-sensitive dye WW375 is typical not only of vertebrates' membranes. The presence of one of the 2 absorption spectra in invertebrates' membranes did not depend on the dye concentration, the time of staining, osmotic concentration and pH of the psysiological solution or ion balance. It is a characteristic of the voltage-sensitive dye-membrane complex itself.
