Final answer:
Contralateral neglect, a condition where patients may not be aware of objects on the left side of their body, is often caused by large lesions in the right parietal lobe.
Step-by-step explanation:
Contralateral neglect is often associated with large lesions of the right parietal lobe. The parietal lobe is responsible for processing somatosensation (touch sensations like pressure, pain, heat, cold) and proprioception (the sense of how parts of the body are oriented in space). It also has a role in attention and in the integration of sensory information to form a single perception (sensory integration). When the right parietal lobe is damaged, patients may not be aware of objects, or even their own limbs, on the left side of their body, a condition known as contralateral neglect. This effect is predominantly observed with lesions in the right hemisphere because it is specialized for attention and spatial processing.
