Fig. 3From: Manganese-enhanced MRI depicts a reduction in brain responses to nociception upon mTOR inhibition in chronic pain ratsComparison of T1-weighted MEMRI following MnCl2 injection in each group. MR imaging was performed for separate groups: control (vehicle), Torin1-, and XL388-infused with electrical stimulation in the hind paw. In control rats, Mn-enhanced signals were observed in the right hemisphere of the brain. However, Torin1- or XL388-infused rats did not show region-specific increases in Mn-signals in the brain. Images were obtained from bregma 3 mm to − 3 mm MRI scanBack to article page
