The paralysis of the body is caused by the presence of lesion due to damage to the structures of the brain. the paralysis occurs on the contralateral side of the damaged structure. This means if the damage occurs in the left hemisphere of the brain, then the right side of the body would be damaged, and if the right hemisphere of the brain is damaged, it causes the paralysis of the left side of the brain.
In this case, the patient's left side is paralyzed, so, the lesion should be present in her right hemisphere.
Hence, the given blank can be filled with right hemisphere.
