title: [Analysis of the cable structure of blue-green algae].
abstract: Peculiarities of electrical responses under local illumination of filamentous cyanobacteria (blue-green algae). Phormidium uncinatum were studied by means of extracellular electrodes. Recording of electrical responses at different distances from the exposure place and comparison of these data with the results obtained on physical model of Ph. uncinatum end expected response parameters computed made it possible to estimate the parameters of the cable which can serve as the object model: RC=440 c/cm2 and lambda min greater than or equal to 0.07 cm. According to these values and taking membrane capacity as C=10(-6) phi/cm2, intracellular resistance Rm=10(7) Ohm and conductivity of the surface membrane G less than or equal to 10(-6) I/Ohm cm2 were estimated.
