Csp antisense incubation blocked the reduction in I_A produced by one-trial conditioning. A, Exemplary I_A current traces elicited from a holding potential of -80 mV to step potentials ranging from -80 to + 40 mV with ΔV = 10 mV. B, Similar current traces elicited from an antisense-treated conditioned type B photoreceptor. C, Group summary data in current density-voltage plot of I_A from the normal control group (n = 7) and groups examined 1.5 h (n = 7), 3.5 h (n = 7), and 16 h (n = 7) after one-trial conditioning. All conditioned groups were incubated in the antisense oligonucleotide. There were no statistically significant changes in the current densities in antisense-treated B cells measured at the different times after conditioning relative to the control group. Error bars represent SD.
