Failures in object recognition called object agnosia. Intact vision outside of object recognition i. e. can detect spots of light in all parts of visual field, normal activity and color vision, etc. Important to dissociate difficulty in object recognition with. It is associated with relatively large lesions in the temporal lobe. Ex: 60 yr old woman began to experience (look at slides ) Inability to name, copy, or recognize visually presented objects. Basic visual functions (color discrimination, luminance discrimination, visual acuity), object identification based on non- visual cues are preserved. A normal visual percept stripped of its meaning. Visual object recognition is impaired (e. g. naming of visually presented objects, categorization, matching by function). Elementary visual perception (e. g. matching and copying) of visually presented forms and objects. Dorsal- vision for action (location, orientation, shape, size) Ventral- vision for perception (location, orientation, shape, size) Is left-right orientation represented in the ventral stream? fmri adaptation.
