Evil Ernie is a powerful necromancer (wizard), but a poor student in psychology. Evil Ernie has taken the brain and body parts from dozens of different cadavers to create his "perfect zombie." While creating this necromantic masterpiece, he, unfortunately, assembled the brain of his zombie incorrectly. Signals from the zombie’s eyes are sent to the part of the brain that processes sound. Signals from the zombie's ears go to its visual processing areas of its brain. Finally, touch sensations are processed in areas associated with taste.
Apparently, Evil Ernie made a mistake installing which part of the zombie's brain?
