Figure 4From: TRPV1 channel-mediated bilateral allodynia induced by unilateral masseter muscle inflammation in ratsConfirmation of cannula placement in the hippocampus. (A) Reconstruction of serial coronal sections of the brain illustrates the bilateral injection sites of the cannulas. The black dots on the schematic illustration of the coronal section of rat brain indicate the placements of cannulas in the brain. (B) Representative microphotograph of the coronal section shows the placements (indicated by circles and arrows) of a pair of cannulas in the CA1 region of the hippocampus.Back to article page
