Comments P.1098 left column bottom paragraph: "Detailed comparative electrophysiological studies from six different mammalian species have been performed in adrenal medullary chromaffin cells (Fig. 1). L-type calcium channels account for nearly half of the whole cell calcium channel current in the cat (ref 5), rat (ref 158), and mouse chromaffin cells (ref 191). But in pigs (primary source 226), bovine (primary sources 9, 157), and humans (primary source 162), L channels carry only 15–20% of the whole cell Ca2+ current."
