Key Notes:
- Visual: Requires high-resolution stimulation of the visual cortex to render realistic images, hence the large number of electrodes and high frequency.
- Auditory: Stimulation of the auditory nerve allows for a wide range of sound frequencies, making it optimal for sound representation.
- Somatosensory: Both read and write capabilities are needed to simulate touch and bodily sensation realistically.
- Mimicry (Facial): Surface stimulation of the facial nerve is necessary to control facial expressions.
