A. Above. Recording sites in infralimbic (IL) and prelimbic (PL) cortex for unstressed (filled circles; IL n = 10, PL n= 12; 3 rats had dual IL and PL placed electrode) and stressed rats (open circles; IL n = 10, PL n=9; 2 rats had dual IL and PL placed electrode) that underwent paired fear conditioning. Numbers indicate position relative to bregma. Below. Raw waveform of a representative neuron recorded from PL of an unstressed rat. Scale bar 25 µV by 0.1 ms. B. Above. Recording sites in infralimbic (IL) and prelimbic (PL) cortex for unstressed (filled circles; IL n = 5, PL n= 9) and stressed rats (open circles; IL n = 6, PL n=8) receiving explicitly unpaired presentations of tone and shock. Numbers indicate position relative to bregma. Below. Raw waveform of a representative neuron recorded from IL of an unstressed rat. Scale bar 25 µV by 0.1 ms.
