Final answer:
The primary visual cortex represents space using a retinotopic visual representation, where the location of objects in the visual field is directly mapped onto specific locations in the visual cortex, with the upper-left visual field being processed in the lower right region.
Step-by-step explanation:
The primary visual cortex is best described as representing space using a visual (retinotopic) representation. This means there is a direct correlation between the position of an object in the visual field and how it is mapped onto the primary visual cortex. Information from the fovea, which is in the center of the retina, is processed in the central portion of the visual cortex, while peripheral information is processed towards the edges. Additionally, the visual field information is inverted and reversed as it enters the visual cortex due to the topographic relationship maintained through the visual pathway, such that up is processed as down, and left as right, although perception is corrected at the level of conscious representation.
Visual stimuli in the upper-left visual field will be processed in the lower right region of the primary visual cortex, because this is the area that corresponds to the superior region of the visual field (which is processed by the inferior region of the retina), and the left visual field is processed in the right side of the visual cortex.
