Under normal circumstances, the left anterior temporal lobe and orbitofrontal cortex of human brain will inhibit the neural activities of the visual system located at the back of the brain and responsible for processing eye signals.

The statement 'Less than 1% of FTD patients can become outstanding artists during their illness' most questions the above conclusion.
