Figure 6. Training in the Cue condition increased the intrinsic excitability of infralimbic neurons.

Figure 6

A. Action potentials were produced by increasing current steps (800 ms, 50 pA steps). Greater spiking occurred in the Cue condition than in the ITI only and No ITI conditions. B. Learning the cue increased the maximum number of action potentials evoked. Sample sizes for subjects (above) and cells (below) are indicated within the bars. C. Representative traces show action potentials generated by 500 pA (left) and 1000 pA (right) current steps for differing behavioral conditions. (Calibration Bars: 20 mV/0.1 s; *: p<0.05 vs. all groups).
