FIGURE 1.
In vivo stress alters the excitability of PFC pyramidal neurons. A and B, representative spontaneous firing recordings and scatter plots of firing rates of PFC pyramidal neurons from nonstressed versus acutely stressed (A) or repeatedly stressed (B) rats. Scale bars, 20 mV, 2 s. *, p < 0.01, t test. C and D, representative spontaneous firing recordings and scatter plots of firing rates of PFC pyramidal neurons showing the effect of PD168077 (40 μm) in stressed (acutely or repeatedly) rats. Scale bars, 20 mV, 2 s. *, p < 0.01, t test.
