The occipital lobe, located in the back of the brain, is primarily responsible for visual functions. These functions include: Mapping the visual world Determining color Identifying familiar faces and objects Transmitting visual information to the temporal lobe Occipital lobe damage can cause a person many different vision problems after brain injury. The temporal lobe and occipital lobe interact closely together, which is why so many symptoms of occipital lobe damage overlap with temporal lobe damage.
