This is why I hate both transhumanism and philosophy in general: neither can tell the difference between the image of an object, and the object itself.
First, cells in the brain itself must be genetically altered so they react to light. Such genetic modification of human cells is still an emerging science and the long term effects are still largely unknown.
It is a puzzlement: How do you assemble and wire an information processing device as complex as the mammalian brain? There are roughly 86 billion neurons in a human brain, forming about a quadrillion synapses. A rat’s brain is just one thousandth that size, but still pretty complex, with 56 million neurons and 500 billion synapses.
Paralyzed rats learned to walk again after a combination of electro-chemical stimulation to their injured spines and intensive rehabilitation therapy.
A new study finds that mice have a distinct neural subsystem that links the nose to the brain and is associated with instinctually important smells such as those emitted by predators.
