Final answer:
An example of cross-lesion experiments involving ventral lesions would likely investigate visual perception, as the ventral visual stream is associated with structures critical for recognizing and identifying objects within the field of vision.
Step-by-step explanation:
An example of cross-lesion experiments involving ventral lesions would likely investigate b) Visual perception. The visual pathway segregates information from the two eyes so that one half of the visual field projects to the opposite side of the brain. Within the visual cortical areas, perception of the stimuli and their location is passed along two streams, one ventral and one dorsal. The ventral visual stream is associated with structures in the temporal lobe important for long-term memory formation, which is directly relevant to processing visual information.
Conversely, the dorsal visual stream interacts with the somatosensory cortex in the parietal lobe, influencing activity in the frontal lobe to generate body movements in relation to visual information. Thus, a ventral lesion would most likely disrupt processes associated with the ventral stream, such as identifying and recognizing objects, which is a fundamental aspect of visual perception.
