Figure 2From: Expression of the transient receptor potential channels TRPV1, TRPA1 and TRPM8 in mouse trigeminal primary afferent neurons innervating the dura Retrograde labeling of dural and facial skin afferent neurons from the same mouse. Representative images of a TG section showing DiI+ dural afferent neurons (A) and FG+ neurons innervating the periorbital skin (B). Note that there is no overlap between the dural and skin afferent neurons as seen in the merged image (C) A total of 425 dural and 360 skin afferent neurons from three mice were counted, respectively).Back to article page
