They conditioned the ferrets to turn their heads left when they heard a tone and to turn them right when they saw a red light.

When the researchers showed a red light to the right eye (controlled by the left hemisphere of the brain), the ferrets turned their heads to the right. This demonstrated that the auditory part of the thalamus had reorganized to receive input from the optic nerve and produce visual responses. The experiment clearly illustrates the neurons in the ferret brains could differentiate into multiple cell types, allowing them to receive stimuli that were not otherwise intended for those areas of the brain.
