Figure 6. Effect of dietary NaCl on phasic bursting activity.

Figure 6

A, an example of current clamp recording of a VP neuron exhibiting phasic bursting activity and its rate metre (10 s binned) of the firing activity when no current was applied. Two periods of burst (a and b) occurred in the presence of benzamil, whereas two other periods of burst (c and d) occurred in the absence of benzamil. B, ISI joint interval histogram along with the mean ISI + standard deviation and the coefficient of variation (CV) for each bursting period indicated as a–d in A. C, intraburst frequency histogram for each bursting period. D, the mean intraburst frequency, burst duration, and ISI CV were not affected significantly by the application of benzamil in VP neurons from animals that were fed a high NaCl diet, compared to that from the control diet group. The mean intraburst frequency was significantly slower among VP neurons from the high NaCl diet group; however, no significant differences occurred in the mean burst duration and ISI CV between the high NaCl and control diet groups.
