Extended Data Fig. 10: Major regions that share reciprocal connections with MOp-ul.

Related to Figs. 1, 2, 3. a, Coronal series of sections highlighting brain regions with both retrograde (CTB, pink) and anterograde (PHA-L, green) labeling following co-injection of both tracers into MOp-ul. Values are in mm relative to bregma. b, c, Higher magnification views (10X) of cortical and thalamic regions shown in (a). This data shows that the MOp-ul shares strong reciprocal connections with (1) other somatic sensorimotor areas (panel b), namely the MOs-ul, contralateal MOp-ul, SSp-ul, SSs and TEa (not shown here); and (2) several thalamic nuclei (c), such as VAL, PO, VM and PF. Scale bars, 1 mm (a), 500 µm (b, c).
