The visual pathway that has been characterized as _______ travels through the dorsal stream to the parietal lobes, whereas the ______ travels through the ventral stream to the temporal lobes. A. the what pathway; the where pathway B. the where pathway; the what pathway C. the opponent process pathway; the trichromatic pathway D. the trichromatic pathway; the opponent process pathway

The visual pathway is the pathway that transmits visual information from the retina to the brain. There are two primary visual processing streams: the dorsal stream and the ventral stream. The dorsal stream is responsible for processing "where" information (location and motion), while the ventral stream is responsible for processing "what" information (recognition and identification).

Now that we understand the differences between the dorsal and ventral streams, we can determine the correct option: A. the what pathway; the where pathway B. the where pathway; the what pathway C. the opponent process pathway; the trichromatic pathway D. the trichromatic pathway; the opponent process pathway The statement describes the first pathway as traveling through the dorsal stream to the parietal lobes. The dorsal stream processes "where" information, so the first blank should be filled with "the where pathway". The second pathway is described as traveling through the ventral stream to the temporal lobes, which processes "what" information, so the second blank should be filled with "the what pathway".

Based on our analysis, the correct answer is option B: The visual pathway that has been characterized as the where pathway travels through the dorsal stream to the parietal lobes, whereas the what pathway travels through the ventral stream to the temporal lobes.
