a Waveforms of narrow and broad spiking neurons. b Distribution of waveform widths (microseconds) fitted with a 2-Gaussian model. Boundary line between narrow and broad spiking neurons is at the intersection point between Gaussians (275, dotted line). Gaussian at the lower width boundary indicates narrow spiking neurons (blue) and the upper boundary indicates broad spiking neurons (dark gray). c Normalized average population SDFs for cue and delay (yellow) epochs for delay tuned narrow spiking neurons. d Median population SDF for narrow spiking neurons over the delay epoch. Data points represent value per electrode array for each session. e Normalized average population SDF for cue and delay epochs (yellow) for delay tuned broad spiking neurons. f Median population SDF for broad spiking neurons over the delay epoch. All error bars are SEM. *<0.05, **<0.01, ***<0.001.
