| 内容記述 | In primate, recognition of facial expressions at a glance is assumed to rely on neural mechanisms in the temporal lobe where characteristics of faces are processed. The temporal cortex is also known to be involved in visual processing about material properties of objects. To investigate how the temporal cortex represents differences in facial surface properties, we recorded neuronal activity in two monkeys while presenting monkey/human faces (three individuals and three expressions each) with different textures (high-gloss, low-gloss, and style-transferred images) in a fixation task. Almost half of the face-responsive neurons showed significant changes in responses to the different textures. The amount of mutual information in the neural responses suggested that the strength of the expression representation was reduced in the style-transferred images, compared to the original. To find behavioral correlates of these neuronal findings, we further investigated effects of the different facial textures on learning processes in a discrimination task. The monkeys were trained to choose one of two facial images by directing a saccade. Their performance was partially impaired in discriminating the expressions of the style-transferred images. Our results indicated that the temporal cortex might play a key role in processing the physical surface properties of faces associated with age, health and emotional states. | |||||
