Expression of Cart. Coronal and off-axis sagittal views of Cart, showing distinct patterns of expression in the somatosensory cortex, accumbens, arcuate nucleus, nucleus of the solitary tract, Edinger-Westphal nucleus, piriform area, and main olfactory bulb. In (a), the quadrat colors correspond to the reference atlas colors of the structures in which they were mapped. A quadrat in the Edinger-Westphal nucleus was selected and the corresponding reference atlas plate displayed. Expression in the right half of the brain was hidden in (b) and the quadrat colors are mapped to the average expression level. Also in (b), several colored transparent meshes for neuro-anatomical structures are shown according to the reference atlas color coding. The olfactory areas are green, nucleus accumbens and striatum-like amgydalar nuclei are blue, the nucleus of the solitary tract is purple, and the arcuate hypothalamic nucleus is red.
