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


Doklady Akademii Nauk SSSR 286(6): 1512-1516
Spectra of absorption optic signals of invertebrate neurons stained with voltage sensitive dyes
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.
