[Response of membranes of mechanosensitive neurons in Astacus astacus to the intracellular injections of solutions under pressure].
Injections of iso- and hypertonic solutions of some potassium salts caused an obvious depolarisation and reduction of electrical resistance in the crayfish slowly adapting stretch receptor neurones' membrane. This response could be eliminated with gadolinium. The stretch-activated channels in the crayfish stretch receptor neurone seem to be affected by an intracellular hydrostatic pressure.
