title: [Mitochondria in a living nerve cell].
abstract: The vital staining of the mechanoreceptor neuron of crayfish with Janus green in concentrations from 0.01 to 0.0005% was performed with electrophysiological estimation of functional state and with controlling the staining procedure by the quantitative analysis of densitographs of cell photonegatives. The possibility of the investigation of mitochrondrial space rearrangements in the neuron soma associated with the functional activity has been shown (optimal dye concentration being 0.001%, the time of staining varying from 30 minutes to 2 hours).
