Representation of object images by combinations of visual features in the macaque inferior temporal cortex.
The ventral visual pathway is essential for object recognition where features necessary for recognition are extracted from object images. This pathway is not directly related to action; nevertheless extraction of features from object images through this pathway is closely related to actions since we determine our behaviour based on sensory information, such as object images in the scene. To link perception and action, we have investigated neural representation of object images in area TE. Area TE, the anterior part of the inferior temporal (IT) cortex, is the final purely visual area in the ventral visual pathway. Since individual neurons in this area respond to features less complex than object images, an object image is supposed to be represented by multiple features. Here, to investigate sets of features necessary for representation of object images, we conducted a combination study of an optical imaging technique and single cellular recordings from anesthetized macaque monkeys.
