1. A method for transmitting neural data extracted from an electrical signal of a non-human mammal to a human, comprising: exposing the non-human mammal to sensory stimuli; recording the electrical signal of the non-human mammal responsive to the sensory stimuli, wherein the electrical signal is in the form of sequences of pulses or pulse trains encoding frequency information of the non-human mammal; processing the recorded electrical signal and converting the processed electrical signal into a digital signal; transmitting the digital signal; and receiving and converting the digital signal into a sensory output perceptible to the human, and applying the sensory output to the human, wherein the step of receiving and converting the digital signal into the sensory output perceptible to the human, and applying the sensory output to the human is performed with a cochlear implant implanted into the human.
