研究表明,梭狀回與臉盲症,即面部辨識能力缺乏症,直接相關。[9]梭狀回中負責人臉認知的部分稱為梭狀回面孔區(英語:Fusiform face area)(fusiform face area, FFA)。梭狀回面孔區可以對不是臉的視覺形象產生像臉的認知,著名的例子如火星上的利比亞山與塞東尼亞區。如果梭狀回面孔區被破壞,就會失去辨識人臉的能力,就連最親密的家人也無法認出來。眼睛負責感知視覺信息,經過視皮層處理後,再由梭狀回辨析,找出生物特徵,藉此來分辨不同的人。梭狀回面孔區中的內梭狀回在接收到人臉信息時被激活,而且在害羞的人與善於社交的人的內梭狀回表現不同。一項研究證實查看陌生人的圖像時,害羞的成年人內梭狀回活化的程度比善於社交的成年人顯着地少。[10]除此之外,另一項研究指出觀看到吸引人的臉孔時內梭狀回活化的程度會更高,主因為美麗的容貌喚起廣泛的神經網絡,包括知覺、獎勵、決策等迴路。[11]
