An organization formed by Jeff Hawkins (inventor of the Palm Pilot)
to study artificial intelligence. Hawkins idea is that lower level
modules in the brain continually try to predict what signals they
will next receive; and it is only when the predictions fail that
signals are passed up to higher (more interconnected) modules, and
it is at the highest level they become conscious thoughts.
I read his book "On Intelligence" a few years ago and recommend it.
It is quite interesting and has some nice ideas on how to implement
an AGI. It conveys a lot of information on neuroscience with a
strong focus on the visual cortex.
He even derives a machine learning model from his ideas, and it
appears to have practical applications:

On the other hand, the excitement appears to have fizzled out after
some initial hype, but maybe I'm just unaware of further progress.
Will look into it.
Pro: I really appreciate his "it's time for computer science to
tackle the brain" attitude, focused on actually building things;
Con: He dismisses the mind-body problem by essentially claiming that
consciousness doesn't even exist. It annoys me, but I can tolerate
it because he delivers interesting ideas and models on the practical
side of things.
Not only I am unable to go to that page, but my browser get really mad
after I tried. Actually, I have lost my connection with the net. I
guess my OS is too old. But from what you say, we might agree on this.
That theory is close to the idea that consciousness is called for when
automated part of the brain don't fit with the situation. We can open
everyday our door without conscious thinking, but if the key appears
to not function well, we get conscious of the situation.
Then, if he claims that consciousness does not exist, well, we have a
problem. Agreed.
