【摘要】：梭狀回面孔區(qū)(fusiform face area,FFA)是視覺皮層上專門加工面孔的區(qū)域。然而,雙側(cè)FFA在面孔加工中的功能分工與協(xié)作還存在爭(zhēng)議。在特異性刺激的加工上,右側(cè)FFA主要負(fù)責(zé)人類面孔類別的知覺,而左側(cè)FFA的功能與面孔精細(xì)特征的感知有關(guān);在皮層可塑性上,右側(cè)FFA主要參與青少年的社會(huì)適應(yīng)學(xué)習(xí),而左側(cè)FFA負(fù)責(zé)成年人的知覺學(xué)習(xí);在面孔網(wǎng)絡(luò)中,二者與不同區(qū)域的連接用以適應(yīng)不同的認(rèn)知需求;他們之間的有向協(xié)作具有任務(wù)特定性。未來(lái)研究需要回答三個(gè)問題:左側(cè)FFA的可塑性程度及這一可塑性是否是認(rèn)知特定的、左側(cè)FFA及其形成的網(wǎng)絡(luò)連接的認(rèn)知意義,雙側(cè)FFA在面孔網(wǎng)絡(luò)中的連接有向性等問題。
[Abstract]:Fusiform gyrus orifice area (fusiform face area,FFA) is a special processing area of the visual cortex. However, the functional division and cooperation of bilateral FFA in face processing are still controversial. In the processing of specific stimuli, the right FFA is mainly responsible for the perception of human faces, while the function of the left FFA is related to the perception of fine features of faces. In cortical plasticity, the right FFA is mainly involved in adolescents' social adaptive learning, while the left FFA is responsible for adults' perceptual learning, and in the face network, the connections between them and different regions are used to adapt to different cognitive needs. Directed collaboration between them is task-specific. Three questions need to be answered in future research: the degree of plasticity of left-hand FFA and whether this plasticity is cognitive-specific, the cognitive significance of left-hand FFA and its network connection, and the connection directivity of bilateral FFA in face network.
