Photic induction of Fos immunoreactivity in the suprachiasmatic nuclei of the blind mole rat (Spalax ehrenbergi).
Exposure to light during the dark phase entrains c-fos expression in cells of the suprachiasmatic nuclei in the blind mole rat (Spalax ehrenbergi). Labeled cells are mainly located in the ventral region of the nucleus where retinal afferents terminate. Despite severe atrophy of the eye and regression of thalamic and tectal structures, the retinal pathways and central mechanisms involved in photoperiodic perception and circadian regulation appear to be similar to those in other rodents.
