Extended Data Fig. 7: Retrograde labelling of gustatory thalamic neurons.
From: The coding of valence and identity in the mammalian taste system
a, b, Injection of the retrograde tracer cholera toxin subunit B–Alexa Fluor 594 in the taste cortex (bitter cortical field; shown in red in a) selectively labels neurons in the taste thalamus (VPMpc; b). Similar results were observed in two animals. c, d, Diagrams of the corresponding brain regions, adapted from the Allen Brain Institute atlas. Scale bars, 500 μm.
