Summary data on the effects of position and intracellular Ca+2 buffering on spike width, and rate of change of voltage of the depolarizing and repolarizing phase of spikes at E12.

Increase in intracellular buffering significantly affected the spike width, and rate of change of voltage of the depolarizing and repolarizing phases of spikes. The data is expressed as mean ± SD (n = 9 cells for each experiment).
