title: Effects of water flow on transmembrane ionic currents in neurons of Helix pomatia and in squid giant axons.
abstract: 1. The effects of water flow through the membrane produced by an osmotic gradient on the ionic currents in Helix neurons and in squid giant axons were studied. 2. Outward water flow had a marked effect on the ionic currents. 3. Cell volume diminution in hypertonic solution was accompanied by a decrease in the number of functioning ionic channels in the neurons. 4. Decrease of the tonicity of the external 10(-8) M TTX-containing solution leads to a transient recovery of the action potentials of the squid.
