Final answer:

Contralateral neglect typically requires damage to the right posterior parietal lobe and frontal eye fields, leading to an individual's unawareness of the left side of the space.

Step-by-step explanation:

Contralateral neglect, often seen as a lack of awareness of one side of space, can occur when there is damage to specific regions of the brain. The two critical areas associated with this condition are the right posterior parietal lobe and the frontal eye fields. The posterior parietal lobe is essentially involved in processing spatial orientation and the control of attention, while the frontal eye fields are linked with voluntary eye movements and attention. When these regions are impaired, especially on the right side of the brain, contralateral neglect can manifest, with individuals failing to notice anything on their left side. This neglect is diagnosed through clinical assessments like the double simultaneous stimulation test and mental status exams that examine sensory discrimination, such as stereognosis and graphesthesia.
