Objects have characteristic attributes (such as two or three-dimensional shape, textute, depth etc) that can be perceived both visually and haptically. Therefore, object-related brain areas may hold a representation of objects in both modalities. Humans have an exceptional ability to estimate the shape of objects from a combination of visual cues such as shading, texture etc. In the human brain, the ventral object visual pathway can generate distinct representations for a virtually unlimited type of texture and depth cues. Haptic perceptionof object or shape categories evokes distinct patterns of neural activation in ventral occipito- temporal cortexthat are widely distributed.
