Glucocorticoid and gamma-aminobutyric acid (GABA) receptors are expressed in the mPFC and are also critical in fear extinction. This study investigated the possible interactive effects of the glucocorticoids and GABAergic system in the IL on the regulation of fear extinction.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Method</h3>\u0000 \u0000 <p>The rats were trained using an auditory fear conditioning task during which they received three conditioned stimuli (tones, 30 s, 4 kHz, 80 dB), co-terminated with the three unconditioned stimuli (footshock, 0.8 mA, 1 s). Extinction testing was conducted over 3 days (Ext 1–3). Thirty minutes before the first extinction trial (Ext 1), the rats received bicuculline (BIC, 1 mg/kg/2 mL, intraperitoneal [i.p.]) as a GABA_A receptor antagonist or CGP55845 (CGP, 0.1 mg/kg/2 ML, i.p.) as a GABA_B receptor antagonist followed by systemic injection of corticosterone (CORT, 3 mg/kg/2 ML, i.p.). Furthermore, separate groups of rats received a bilateral intra-IL injection of BIC (100 ng/0.3 µL/side) or CGP (10 ng/0.3 µL/side) followed by a systemic injection of CORT (3 mg/kg/2 ML, i.p.) before the first extinction trial (Ext 1). The extracellular signal-regulated kinase (ERK1) and cAMP response element-binding (CREB) activity in the IL was examined by Western blot analysis after Ext 1.</p>\u0000 </section>\u0000 \u0000 <section>\u0000 \u0000 <h3> Finding</h3>\u0000 \u0000 <p>The results indicated that systemic CORT injection facilitated fear extinction and increased the expression of ERK1 but not CREB in the IL.
