Before revision:  We further predict that varying the conductance gating of delayed rectifier K^{+} channels modifies oscillatory activity patterns of \beta-cell population lacking intercellular coupling, which significantly affect Ca^{2+} concentration and insulin secretion.
After revision:  We further predict that varying the whole-cell conductance of delayed rectifier K^{+} channels modifies oscillatory activity patterns of \beta-cell population lacking intercellular coupling, which significantly affect Ca^{2+} concentration and insulin secretion.
