Christof Koch is a neuroscientist who studied the neural bases of consciousness.  He wanted to study the brain and human consciousness and how we see what we see through our nerve cells and learn to identify something through our nerve cells.  He believed that a computer properly programmed to copy the connections of the human brain could itself be consciousness.
When I saw this model it made me think of the Matrix/Allegory of the Cave as we've been discussing what we see and how we perceive it and make it real to us.  Our senses see something and that is what we believe it is.
