Final answer:
A stroke in the contralateral posterior parietal lobe of the brain would cause complete contralateral sensory loss.
Step-by-step explanation:
A stroke in the contralateral posterior parietal lobe of the brain would cause complete contralateral sensory loss. The posterior parietal lobe is responsible for processing sensory information, such as touch, pain, and proprioception. When this area is damaged, the person would lose sensation on the opposite side of the body.
