Final answer:
The patient with an inability to attend to the left side of objects and the left side of her body likely suffered damage to the right parietal lobe, which can cause hemispatial neglect.
Step-by-step explanation:
The patient described in the question likely suffered damage to the right parietal lobe. This region is responsible for processing sensory input and is involved in spatial awareness and perception. Damage to the right parietal lobe can lead to conditions like hemispatial neglect, where there is a lack of awareness of one side of space. The symptoms mentioned, such as the inability to attend to the left side of objects and the left side of the body and thinking that her own left arm belongs to someone else, are indicative of such neglect and are consistent with right parietal lobe damage. Therefore, the correct answer is B) Right parietal lobe.
