In turn, the concept of awareness, consciousness and working memory a so closely intertwined that research in any of these subjects is, by default, research in all the others. In this book, he makes a strong case. It turns out that we can be conscious while missing big chunks of our brain. Evidence from such sad situations, along with EEG and fMRI studies, allow us to zero in on the brain functions that are necessary and sufficient for consciousness. Bor provides extensive examples of experiments that reveal the limits of consciousness and how it can be "taken apart" in various ways. One of is central ideas is "chunking". He visualizes working memory has having a limited capability to handle "chunks" - perhaps just 4 at a time (whatever "chunks" are). To deal with this limit, the brain (mainly the PPC), det...
