Figure 2

(A) Confocal microscope microphotograph of a coronal section of the brain in animal RE9 at Bregma 2.16 mm stereotaxic coordinates, showing double labeled neurons in S1 and Ins cortices. (B) Microphotograph showing the barrel zone of S1 cortex in animal RE8 where the fluorescence was combined with cytochrome oxidase technique. Asterisk corresponds to the barrel zone, white arrows points the retrograde labeled neurons. Cytochrome oxidase labeled neurons located in the white square, are magnificated in the inset. (C) Microphotograph of S1 cortex in animal RE9 showing the FlGo and FB labeled neurons. Black arrow shows the double labeled neurons. Inset: Confocal microscope detail of a single FlGo labeled neuron (up) and double labeled neuron (down). Calibration toolbar: A: 500 µm, B: 260 µm, inset 200 µm C: 300 µm, inset 50 µm. Abbreviations: Cg: cingulate cortex, Ins: insular cortex, M: motor cortex, S1: primary somatosensory cortex.
