Extended Data Fig. 5: Representative stereotaxic injections in the DP and other MPF areas.

a, Drawings illustrate the locations of representative injection sites, their surgical case IDs, and tracer types over the Allen Reference Atlas (ARA11). The atlas wire frame for ARA levels 38-41 incorporated updated DP boundaries, ILA and TTd. A total of 18 anterograde and 15 retrograde injections in DPs, DPd, ILA, PL, ACAv, and ACAd were quantitatively analysed. Additional 35 cases (10 in DPs/DPd; 25 in other MPF areas) supported validation and whole-brain wiring diagram construction. See SI Fig. 1 for refined DP borders. b, Representative microphotographs of retrograde (CTB) and anterograde (PHAL, AAV) tracer injections made into DPd, DPs, ILA, PL, ACAd and ACAv. Scale bars = 500 µm.
