【摘要】：梭状回面孔区(fusiform face area,FFA)是视觉皮层上专门加工面孔的区域。然而,双侧FFA在面孔加工中的功能分工与协作还存在争议。在特异性刺激的加工上,右侧FFA主要负责人类面孔类别的知觉,而左侧FFA的功能与面孔精细特征的感知有关;在皮层可塑性上,右侧FFA主要参与青少年的社会适应学习,而左侧FFA负责成年人的知觉学习;在面孔网络中,二者与不同区域的连接用以适应不同的认知需求;他们之间的有向协作具有任务特定性。未来研究需要回答三个问题:左侧FFA的可塑性程度及这一可塑性是否是认知特定的、左侧FFA及其形成的网络连接的认知意义,双侧FFA在面孔网络中的连接有向性等问题。
[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.
