通过量化在面部（绵羊与人类）可以（面部直立）和不能（面部倒置）被区分的情况下改变的 c-fos mRNA 表达，在绵羊中研究面部识别过程中的神经激活模式。暴露于直立面孔选择性地增加了右侧下颞叶皮层的表达，显着高于左侧，并且主动选择直立面孔还增加了基底杏仁核和海马体（CA1-4）双侧的表达。暴露于倒立的面孔并不会导致右下颞叶皮层、杏仁核或海马体的激活增强，而是增加了布罗卡对角带、顶叶和扣带皮层的表达水平。这些结果表明，绵羊对直立面部的辨别优先涉及右侧颞叶皮层，就像人类一样，并且在此类面部之间进行主动选择的表现可能还涉及基底杏仁核和海马体。
Patterns of neural activation during face recognition were investigated in sheep by quantifying altered c-fos mRNA expression in situations where faces (sheep vs. human) can (faces upright) and cannot (faces inverted) be discriminated. Exposure to upright faces selectively increased expression significantly more in the right inferior temporal cortex than in the left, and active choice between upright faces additionally increased expression bilaterally in basal amygdala and hippocampus (CA1-4). Exposure to inverted faces did not lead to enhanced activation in the right inferior temporal cortex, amygdala or hippocampus but instead increased expression levels in the diagonal band of Broca, parietal and cingulate cortices. These results show that discrimination of upright faces in sheep preferentially engages the right temporal cortex, as it does in humans, and that performance of active choices between such faces may additionally involve the basal amygdala and hippocampus.
