    Notes: [Auszug] The suction pipette method is similar to that used in snail neurones and the details have been published elsewhere10. The main difference in the present experiments is that the tip diameter of the suction pipette was smaller, about 20 ??, and the measured tip resistances ranged from 150 to 250 kfl. ...

    Notes: [Auszug] Neurones from the circumoesophageal ganglia of Helix aspersa were exposed by removing the capsule of the ganglion. Part of a neurone of about 100 |xm diameter was sucked into the tip of a 50-|xm diameter suction pipette and removed from adjacent neurones and its own axon by pulling it free of the ...

    Notes: [Auszug] We have developed a simple suction pipette method with which individual nerve cell bodies can be isolated, perfused internally and voltage clamped. This method will be valuable in the study of individual cell membranes of excitable or inexcitable tissues. Fig. 1 Schematic of experimental setup. D1 ...

    Ionic permeabilities of anAplysia giant neuron (1975)
    Springer
    The journal of membrane biology 21 (1975), S. 353-374 
    Details

    Notes: Summary In a giant neuron ofAplysia californica, permeabilities and conductances obtained by measuring net fluxes of Na+, K+ and Cl− with ion-specific microelectrodes were compared with those obtained by measuring transmembrane current and potential changes when the three ions were varied in the external solution. Net fluxes were measured with ion-specific microelectrodes, after blocking metabolic processes, thus allowing movement of ions down their electrochemical gradients. Permeabilities and conductances obtained from the “chemical” measurements (i.e., ion-specific electrodes) were generally comparable to the values obtained from “electrical” measurements. Where discrepancies occurred, they could be explained by showing that some of the assumptions necessary to use the “electrical” method were not quantitatively true in this system. The absolute magnitudes of the permeabilities are significantly less than those found in many axonal preparations. There is also a relatively highP Na/P K ratio. The selectivity of the membraneagainst ions such as Tris+ and MeSO 3 − is not good, Tris+ being nearly as permeable as Na+ and MeSO 3 − about one-half as permeable as Cl−. These properties may be characteristic of somal membranes.
