Fig. 3. The elevation of intracellular Ca²⁺ reduces spike capacity but not precision in cortical regular-spiking neurons. Superimposed waves of spikes under control (A) and adenophostin-A (B) infusion. Vertical lines are spike-locking phases, and horizontal lines are threshold potentials (V_ts). (C) The inter-spike interval (ISI) of sequential spikes under control ( ${triangleup}$ ) and adenophostin-A ( ${blacktriangleup}$ ) infusion, in which ISI values relevant to the same number in sequential spikes are statistically different (P<0.01). (D) The standard deviation of spike timing (SDST) under control ( ${triangleup}$ ) and adenophostin-A ( ${blacktriangleup}$ ) infusion.
