Store operated response in salamander cones shows mixed responses to L-type inhibition.

Effect of 200 μM D-cis diltiazem on baseline [Ca2+]i and SOCE in cone inner segments (n = 37). In most cells, neither baseline [Ca2+]i nor SOCE were affected by D-cis diltiazem. A subset of cones responded to L-type inhibition with both baseline decreases (left- and upper-most cell). The baseline response is plotted in the left-most column. SOCE responses (measured as peak amplitudes of depletion-evoked Ca2+ overshoots) are plotted on top.
