Buongiorno, Everything List!
I have been lurking here since mid-2009, and had hoped to have a
better intellectual foundation to support me before I posted anything
of my own, but I would really like to ask this question.
Giulio Tononi's Integrated Information Theory (IIT) states that
consciousness is integrated information. In "Consciousness as
Integrated Information: a Provisional Manifesto" he writes, referring
to the sensor chip in a digital camera:
"In reality, however, the chip is not an^ integrated entity:
since its 1 million photodiodes have no way^ to interact, each
photodiode performs its own local discrimination^ between a low and a
high current completely independent of what^ every other photodiode
might be doing. In reality, the chip^ is just a collection of 1
million independent photodiodes, each^ with a repertoire of two
states. In other words, there is no^ intrinsic point of view
associated with the camera chip as a^ whole. This is easy to see: if
the sensor chip were cut into^ 1 million pieces each holding its
individual photodiode, the^ performance of the camera would not change
Considering this, can consciousness be Turing emulable? That is,
can a Turing machine integrate information? I want to expand my
question here, but I don't have the knowledge to do so without
distracting from the main question I'm asking. So, all I can say is,
details greatly appreciated!

Sure. Consider a Mars Rover. It has a camera with many pixels. The
voltage of the photodetector of each pixel is digitized and sent to a
computer. The computer processes the data and recognizes there is a
rock in its path. The computer actuates some controller and steers the
Rover around the rock. So information has been integrated and used.
Note that if the information had not been used (i.e. resulted in action
in the environment) it would be difficult to say whether it had been
integrated or merely transformed and stored.
