Nervo Craniano Zero (2012)

Bruna Bloch, a successful writer, hires her former boyfriend to experiment a creativity inducing brain chip called Melpomene(the Greek muse of tragedy). Before trying on herself, they use Cristi, a naive country girl, as guinea pig. The chip, installed on the elusive cranial nerve zero, shows results beyond expected. Cristi can no longer sleep, eat, smell nor can she die. What seemed to be a breakthrough in science becomes a horrific nightmare.
