a, Schematic illustrating fiber photometry measurements in a freely behaving mouse. A representative image of an experimental arena captured by an overhead camera is shown in the bottom right. b, Histology showing expression of MTRIAOT (green) and the placement of an implanted cannula. DAPI (blue) was used for counterstaining nuclei. Scale bars, 10 cm (a) and 1 mm (b).
