Brain Dysfunction by Location
Occipital Lobe Damage
 Cerebrum None The occipital lobes have the following functions: Processing and interpreting vision Enabling people to form visual memories Integrating visual perceptions with the spatial information provided by the adjacent parietal lobes Ifboth sidesof the occipital lobe are damaged, people cannot recognize objects by sight, even though the eyes themselves are functioning normally. This disorder is called cortical blindness. Some people with cortical blindness are unaware that they cannot see. Instead, they often make up descriptions of what they see (called confabulation). This disorder is called Anton syndrome. Seizuresthat involve the occipital lobe can cause hallucinations involving vision. For example, people may see lines of color when they look in a certain direction.
