In area 24, most of the labeled cells were found in the rostralmost part of area 24a, and some were scattered in area 24b and the more caudal part of area 24a (Figs. 1B, C, E, 2B, C). [...] labeled cells in layers II-III, V, and VI of area 24a[...] Half of the labeled cells are in layer V. Collator note: strong labeling in the rostral third of the ACAv. See Fig. 1E. Swanson Atlas Levels 11-14.

In area 24, most of the labeled cells were found in the rostralmost part of area 24a, and some were scattered in area 24b and the more caudal part of area 24a (Figs. 1B, C, E, 2B, C). Collator note: very weak labeling in the mid-rostrocaudal part of the ACAd. See Fig. 1E. Swanson Atlas Levels 15-17.

Most of these labeled cells were located in area 24a and ventral area 24b at rostrocaudal levels between the anterior commissure and the genu of the corpus callosum (Fig. 1G, H, J). See Fig. 1E. Collator note: Swanson Atlas Levels 11-14.

most of the labeled cells in area 24 were observed at the level just caudal to the anterior commissure (Fig. 1M,O). At this level, area 24b contained more labeled cells than area 24a (Fig. 1O). Collator note: the position of the terminal field is caudal, Swanson Atlas Levels 23-24.

more labele cells were present in area 24b than in area 24a (Figs. 1Q–T, 2E,F, Table 1). The labeled cells in both areas were most numerous in layer VI of caudalmost parts…Collator note: weak-moderate labeling in the caudal ACAd. Swanson Atlas Levels 21-24.

Fewer cells were labeled in more rostral parts of areas 24a and 24b (Fig. 1R–T). Collator note: weak and very weak labeling in the mid-rostrocaudal ACAd and Acav. Swanson Atlas Levels 18-20.

few cells scattered in areas 24a and 24b and the secondary motor area at rostrocaudal levels near the anterior commissure (Fig. 3A–E, Table 1). Collator note: weak labeling of all these regions mid-rostrocaudally, Swanson Atlas Levels 18-22.

fewer cells in area 24a and the medial part of the secondary motor area at the level of the anterior commissure. In areas 24a and 24b, relatively few labeled cells were present in layer VI and tended to be located in its superficial part (Fig. 3H). Collator note: labeled neurons in the ACAv are almost everywhere. Swanson Atlas Levels 11-23.

Collator note: labeled cells mostly in the caudal part, but also in the rostral part. Swanson Atlas Levels 18-26.

labeled terminals were observed mainly in the ventral part of rostral area 29c (Fig. 4B,C,E). Collator note: Swanson Atlas Levels 25-34.

Some labeled terminals were also observed in the rostral half of area 29d, where they were located laterally at rostral levels (Fig. 4B,E). Collator note: Swanson Atlas Levels 25-34.

Collator note: few labeled terminals in the rostral RSPagl, layers II-III. See Fig. 4D, Swanson Atlas Levels 38-39.

Collator note: see Fig. 4D and 4E.

Collator note: see Fig. 4D and 4E.

Collator note: strong labeling of the ACAv, caudally, tending ventrally, across all layers. See Fig. 4F, Swanson Atlas Levels 24-25.

Collator note: weak-moderate labeling of the ACAd, caudally, mostly layers V-VI. See Fig. 4F, Swanson Atlas Levels 24-25.

Collator note: weak-moderate labeling of the rostral RSPagl and caudal RSPd, and RSPv. Labeled layers in RSPagl are mostly II-III, while for RSPd and RSPv V-VI. Swanson Atlas Levels 38-39.

Collator note: weak-moderate labeling of the rostral RSPagl and caudal RSPd, and RSPv. Labeled layers in RSPagl are mostly II-III, while for RSPd and RSPv V-VI. Swanson Atlas Levels 38-39.

Collator note: weak-moderate labeling of the rostral RSPagl and caudal RSPd, and RSPv. Labeled layers in RSPagl are mostly II-III, while for RSPd and RSPv V-VI. Swanson Atlas Levels 38-39.

Collator note: strong labeling of the RSPv-b/c, rostrally, tending ventrally. Labeled layers are V-VI. See Fig. 4H, Swanson Atlas Levels 38-39.

Collator note: no label in RSPv-a, rostrocaudally. See Fig. 4I and 4J.

Collator note: labeling of the RSPv-a, rostrocaudally, with a tendency toward caudal.
