Extended Data Fig. 6: Characterization of Fezf2^{BLa → OT} and Fezf2^{BLa → NAc} neurons.

a, Confocal images of coronal brain sections containing the BLa or BLp along the antero-posterior axis from a representative Fezf2-CreER mouse, showing the distribution of NAc- or OT-projecting Fezf2⁺ neurons. In the rightmost panel are high magnification images of the boxed area in the corresponding overlay images. b, A schematic of the approach to target OT- or NAc-projecting Fezf2⁺ neurons in the BLA. c, Quantification of the proportion of overlapping neurons among Fezf2^{BLA → NAc} neurons (13 ± 3.1%) or Fezf2^{BLA → OT} neurons (11.8 ± 3.2%; 4 mice). d, Quantification of the OT- or NAc-projecting Fezf2⁺ neurons in the BLa and BLp. e, Quantification of the expression of PPP1R1B in NAc- or OT-projecting Fezf2⁺ neurons, in the BLa and BLp (n = 4; Friedman test (F-stat 10.1) with Dunn’s post-hoc test: P = 0.003; n.s., P > 0.05). Data are presented as mean ± s.e.m.
