Panel A and B: CRF-ir expression in the contralateral CeAmy (A) and ipsilateral CeAmy (B) of nerve-cuffed mice; T-test, t14 = 4.3, P < 0.001. Panel C and D: ΔFosB-ir in the dorsal horn of the spinal cord after 15 days of neuropathic pain in mice with ablation contralateral to the nerve cuff (C) and ipsilateral to the nerve cuff (D), T-test, t27 = 3.9, P < 0.001. Abbreviations: BLA - basolateral amygdala, CeC - centrocentral nucleus, CeM -cenrtromedial nucleus and CeL- centrolateral nucleus. Roman numerals from I to V indicate spinal cord laminae. Scale bar = 200 μm in A and B and scale bar = 100 μm in C and D.
