If you find the subject interesting and would like to read more, I recommend Jeff Hawkins' A Thousand Brains: A New Theory of Intelligence, which was released earlier this year and covers a theory that a large part of your brain is made of 150,000 near-identical subsystems called "cortical columns." It's geared toward people who have little background in neuroscience. You might also follow up with Anil Seth's "controlled hallucination" theory in Being You: A New Science of Consciousness. If you prefer to pay for this knowledge with just time rather than also money, on YouTube there are three videos from Numenta that cover Jeff's book, and then there's a Ted talk by Anil on consciousness.
