Coronal sections depicting core of tracer deposits into ALO, PLO, or PVO, illustrated at the level of maximal tracer deposit. (A) Stars and oval shapes represent the intended and the observed injection sites core, respectively. Injections whose core fell outside the orbitofrontal cortex or in which the tracer did not diffuse are not represented here (see instead Fig. S1). n ALO = 6, n PLO = 5, n PVO = 4 injections. (B) Example injection sites of triple-labelled brain. Distances shown are distances from bregma in mm. AF: Alexa Fluor; AId: agranular insular cortex, dorsal part; AIv: agranular insular cortex, ventral part; ALO: lateral orbitofrontal cortex, anterior part; CTB: cholera toxin subunit B; DLO: orbitofrontal cortex, dorsolateral area; IL: infralimbic cortex; MO: orbitofrontal cortex, medial part; LO: orbitofrontal cortex, lateral part; M1: primary motor cortex; M2: secondary motor cortex; PL: prelimbic cortex; PLO: lateral orbitofrontal cortex, posterior part; PVO: ventral orbitofrontal cortex, posterior part; VO: orbitofrontal cortex, ventral part.
