Calretinin in the Sp5C of mTBI mice potentially involved in trigeminal pain. a Reorganization of calretinin-ir was observed from outer lamina II to lamina I of mTBI mice (n = 3; Bregma coordinate ~ 8.2). Full extent of this reorganization is shown in Additional File 7. b Representative images from sham and mTBI mice at Sp5C show the shift in calretinin-ir from lamina II to lamina I. Scale bar = 50 µm. c Increased number of calretinin-ir neurons in the rostral Sp5c compared to the caudal Sp5c of mTBI mice. **, p < 0.01
