Some visual-form areas are really task areas | Neuro-patch
There are two paths for visual information, one to the motor areas (dorsal 'where' stream) and one to the areas concerned with consciousness, memory and cognition (ventral 'what' stream). The visual ventral stream has areas for the recognition of various categories of object: faces, body parts, letters for example. But are these areas really 'visual' areas or can they deal with input from other senses? There is recent research into an area concerned with numerals. (see citation below) There are some reasons to doubt a 'vision only' processing in these areas. "...cortical preference in the 'visual' cortex might not be exclusively visual and in fact might develop independently of visual experience. Specifically, An area showing preference for reading, at the precise location of the VWFA (visual word-form area), was shown to be active in congenitally blind subjects during Braille reading... large-scale segregation of the ventral stream into animate and inanimate semantic categories have
