] Albert Titus, an assistant professor of electrical
] engineering at the University at Buffalo, New York, has
] created a silicon chip that mimics the structure and
] functionality of an octopus retina.
]
] His "o-retina" chip can process images just like an
] octopus eye does. The chip could give sight to rescue or
] research robots, allowing them to see more clearly than
] human eyes can in dark or murky conditions.

Titus notes, "the retina is an extension of the brain, so where does the distinction between seeing and perceiving begin and end?"
