Negative changes indicate decreases in tail current amplitude, and positive changes indicate increases. Numbers in parentheses indicate number of cells responding relative to number of cells tested. Percentage changes are calculated only from those cells that responded.

F4-150: p < 0.05;

F4-160: p < 0.005;

F4-165: p < 0.001. Comparisons of control current with currents seen in the presence of NA (paired t test).
