Control activity and recovery from high potassium saline are unchanged by previous exposure to 2.5x[K⁺] saline

(A) Three-second segments of PD neuron activity for three animals (#2, 7, and 13, same animals as shown in Figure 2) 10 min after exposure to each high potassium saline perturbation.

(B and C) Average burst frequency (B) and number of spikes per burst (C) for each neuron, and across all neurons, in control saline is unchanged after exposure to high potassium saline. For (B) and (C), the median value is represented by the thick red line, and each preparation’s variance is represented in error bars ±SEM.

(D and E) Rebound of spiking activity (D) and PD dip value (E) plotted by wash number. Averages for spikes per minute and dip statistic are plotted in the dark line, with ±SEM lighter shaded regions around them.
