Immunofluorescence image showing the outline of the SCN (in blue) and the two populations that together encode for circadian time in mammals. Astrocytes are in green (expressing the astrocytic marker GFAP), whereas neurons of the dorsal SCN are in magenta (marked by expression of the Grin2C-tdTomato marker). This composite image only has representative value. Image credit: Hastings Group, MRC Laboratory of Molecular Biology, UK.
