Damage to which parietal lobe is more likely to cause left hemifield neglect?

Explanation:
The right parietal lobe is the region most responsible for steering attention through space, especially to the left side. When this area is damaged, the brain's ability to attend to stimuli in the left hemifield drops, so the person may ignore or fail to respond to things on the left even though their eyes and vision are intact. This left hemifield neglect is a hallmark of right parietal injury. In contrast, damage to the left parietal lobe more commonly affects attention toward the right side, and neglect on the left is less typical. Visual field defects from occipital lobe damage reflect a different kind of problem (actual loss of vision in a field) rather than a failure to attend to that space.
