BAPTA affects electrosensory lateral line lobe (ELL) pyramidal cell firing properties in vivo. Asterisk indicates significant difference (P < 0.05). A: BAPTA decreases the cell’s refractory period. B: BAPTA increases burst fraction (i.e., fraction of ISIs <10 ms). C: BAPTA significantly decreases the time constant obtained by fitting an exponential to the decaying part of the ISI distribution. D: BAPTA significantly increases the number of spikes per burst. E: BAPTA significantly decreases the AHP. F: BAPTA induces a depolarization during bursting. G: the effects of BAPTA were different for cells of different morphologies. BAPTA tended to have the greatest effect in cells that had low firing rates as shown by a significant negative correlation between the change in burst fraction induced by BAPTA and the cell’s mean firing rate under control conditions. The asterisks indicate statistical significance at the P = 0.05 level.
