Web6,11) and for single somatic recordings after cell-attached recordings to minimize the dilution of the intracellular milieu 14. The whole-cell somatic recording following the cell-attached recording is therefore kept short … WebCell-attached and excised patches; whole-cell recording. Fig. 2 summarizes the main modes of gigaseal recording. Much work is done using patches in the cell-attached mode, but the resting potential of the cell is not known and neither intra- nor extracellular ionic concentrations can be changed easily. For

The inside-out and outside-out techniques are called "excised patch" techniques, because the patch is excised (removed) from the main body of the cell. Cell-attached and both excised patch techniques are used to study the behavior of individual ion channels in the section of membrane att…
WebIn the cell-attached mode, the membrane patch is left intact allowing the recording of ion channels within the patch as well as action potentials. Applying a pore-forming agent, such as amphotericin, in the pipette results in a perforated patch, which establishes electrical continuity whilst preventing the dialysis of intracellular proteins ...
