Fig. 1From: Manganese-enhanced MRI depicts a reduction in brain responses to nociception upon mTOR inhibition in chronic pain ratsSchematic illustrating the experimental design. All rats underwent behavioral testing prior to nerve injury and at postoperative days (POD) 1, 4, and 7. On each behavioral testing day, the mechanical threshold was assessed using an electronic von Frey filament. At POD 7, rats were prepared for MEMRI experiments to determine Mn-enhanced changes after evoked pain. MEMRI was performed following T2 scans, and regional Mn enhancement in the whole brain of experimental groups was comparedBack to article page
