Visual agnosia is a condition where a person cannot recognize objects visually, despite having intact vision. This can occur because there are multiple neural pathways for processing visual information: one pathway processes the "what" (identifying objects), and another processes the "how" (guiding movements towards objects). In visual agnosia, the pathway for identifying objects may be damaged, while the pathway for guiding movements remains intact, allowing the person to reach for and grab objects without being able to recognize them.
