The somatotopic organization of the visual cortex is described as:

• A. Retinotopic
• B. Tonotopic
• C. Somatotopic
• D. Visuotopic

Answer: (D)

The visual cortex uses a map of the visual field to organize its responses. This topographic layout means that neighboring points in what we see map to neighboring neurons on the cortex, preserving spatial relationships from the eyes to the brain. This arrangement is described as visuotopic, capturing the idea of a cortical map of visual space (and it’s often discussed as retinotopic as well, since the map originates from retinal input). Because of this organization, inputs from opposite sides of the visual field end up represented in opposite hemispheres, and the fovea gets a disproportionately large cortical area due to higher acuity there.

So, describing the visual cortex’s organization as visuotopic directly conveys that it maps visual space onto the cortex. The other terms refer to different senses or, in the case of retinotopic, describe a related but more specific retinal reference frame.
