The left hemispere of the cortex deals with the right visual field,
the right hemispere deals with both left and right. There damage to
the left hemispere has no blinding effect, language could be impaired.
When the right hemisphere is damaged (through a stroke), then the patient
neglects his right half of the world and body. He/she might eat only the
left side of the plate or put make-up on the left side only.
