Report ID	Sending structure	Receiving structure	Projection strength	Technique	General description projection	Collator	Associated reference
89770	Primary somatosensory area	Supplemental somatosensory area	strong	biotinylated dextran amine (BDA)	Local transport of the tracer revealed dense terminal labeling in SII cortex and in a smaller caudal area that represents PPC.		Smith J.B. & Alloway K.D., 2013
89774	Primary somatosensory area	Supplemental somatosensory area	moderate	biotinylated dextran amine (BDA)	but many retrogradely-labeled neurons were present in both the septal and barrel columns as previously reported.		Smith J.B. & Alloway K.D., 2013

General description technique/protocol: multiple BDA deposits were placed so that the tracer infiltrated large portions of the SI barrel region. Collator note: no specification of the actual positions of the injection site. See Fig. 3B.

89772	Primary somatosensory area	Primary motor area	strong	biotinylated dextran amine (BDA)	In MI cortex, a large bundle of labeled projections from SI coursed rostrally through cortical layer VI and abruptly turned toward the pial surface to form a vertical column of labeling (Figure 3C ). The labeled column was 400�500 ?m in width and extended upwards from upper layer VI to layer I. Inspection of the adjacent Nissl-stained section indicated that this labeling was located in the MI region that represents the transition from AGm to AGl. Collator note: seee Fig 3D, Swanson Atlas Levels 8-11 ( +3.00 - +1.50 mm from bregma).		Smith J.B. & Alloway K.D., 2013
89777	Primary somatosensory area	Primary motor area	strong	biotinylated dextran amine (BDA)	[�] corresponding whisker representations were injected in both areas as indicated by the presence of BDA-labeled neurons at the FR injection site. Collator note: rostral double labeling of the Mop, rostrally. See Fig 5D, Swanson Atlas Levels 8-10 ( +3.10 - +2.20 mm from bregma). The amount of overlap is about 18-19% for SI and SII in layers III and V of the primary motor cortex (Fig. 7A).		Smith J.B. & Alloway K.D., 2013

89773	Primary somatosensory area	Secondary motor area	moderate/strong	biotinylated dextran amine (BDA)	Collator note: labeling in the rostral MOs, adjancent to the MOp, and its transitional zone (TZ).

89778	Primary somatosensory area	Secondary motor area	moderate/strong	biotinylated dextran amine (BDA)	Collator note: rostral double labeling in MOs, dorsally. See Fig 5D, Swanson Atlas Levels 8-10 ( +3.10 - +2.20 mm from bregma).		Smith J.B. & Alloway K.D., 2013

89775	Supplemental somatosensory area	Primary motor area	moderate/strong	biotinylated dextran amine (BDA)	SII projects to the transitional zone between AGm and AGl (Figures 4C), which is the same MI region that receives projections from SI. [...] the labeled projections to MI appeared weaker and were less extensive than the terminal labeling observed after tracer injections in SI. The SII projections innervated layers II, III, and the lower part of layer V of MI, but were weaker in upper layer V and did not innervate any part of layer VI. The SII projection terminals were more concentrated in the rostral half than in the caudal half of MI (Figure 4D). Collator note: +3.20 - +2.50 mm from bregma, Swanson Atlas Levels 8-11.		Smith J.B. & Alloway K.D., 2013
89779	Supplemental somatosensory area	Primary motor area	strong	biotinylated dextran amine (BDA)	[�] corresponding whisker representations were injected in both areas as indicated by the presence of BDA-labeled neurons at the FR injection site. Collator note: rostral double labeling of the Mop, rostrally. See Fig 5D, Swanson Atlas Levels 8-10 ( +3.10 - +2.20 mm from bregma). The amount of overlap is about 18-19% for SI and SII in layers III and V of the primary motor cortex (Fig. 7A).		Smith J.B. & Alloway K.D., 2013

General description technique/protocol: BDA was injected so that it infiltrated much of SII without invading SI. Collator note: unclear what is the topographical position of these injections in SSs.

89776	Supplemental somatosensory area	Secondary motor area	moderate	biotinylated dextran amine (BDA)	Collator note: labeling in the rostral MOs, adjancent to the MOp, and its transitional zone (TZ), but less extensive than in SSs cases.

89783	Posterior parietal association areas	Primary motor area	moderate	biotinylated dextran amine (BDA)	In contrast to SII, the PPC projections were concentrated in the caudal half of MI. Collator note: the labeling pattern is not shown in the reference. Figure 7 shows a little overlap of the PPC projections to MOp and MOs, respectively. The same with the projections from SSp and PPC, respectively, in MOp.		Smith J.B. & Alloway K.D., 2013

General description technique/protocol: Collator note: BDA injection in the rostral PTLp. See Fig.6B.

89781	Posterior parietal association areas	Secondary motor area	moderate/strong	biotinylated dextran amine (BDA)	Virtually all labeled projections from PPC were located in AGm proper (see Figures 6C). In each coronal section that was inspected, the PPC projections terminated in the region medial to the AGm�AGl transition zone (Figure 6D). The labeled terminals were intermingled with labeled neuronal soma, which indicates that PPC and AGm are reciprocally connected. Collator note: Fig 6D, +2.50-+ 1.42 mm from bregma, Swanson Atlas Levels 9-12.		Smith J.B. & Alloway K.D., 2013
