" We live in the era of the “bottom line” mentality, with TED talks, sound bites, and news summaries. There is so much information to digest, we can only hope to grasp the world with compact and seemingly complete stories. We don’t want to be left dangling.
We are all suckers for this information diet, and we all have come to depend on it, just like we have all succumbed to the instant gratification of texting and cell phones. And yet what separates the dilettante from the sophisticate is the appreciation that everything is not simple. The trick seems to be able to talk clearly while remaining fully aware of the underlying complexity of any story. For me it is the overwhelming realization that when trying to figure out how the brain does its masterful trick of
enabling minds, we are barely at the starting line. Dig as deep as you want into human history: As long as there is a written record of thought, there is a record of humans wondering about the nature of life. It becomes obvious that all of us are just hopping into an ongoing conversation, not structuring one with a beginning, a middle, and an end. Humans may have discovered some of the constraints on the thought processes, but we have not yet been able to tell the full story. "

" Adding to our understanding of why the brain seems undisturbed by disconnections was not only the notion that it was, in a sense, sending half its decisions into the realm of the unconscious; it was also the discovery of the “interpreter.” This special left brain system kept note of all the behaviors that resulted from the many mental systems. It appeared to be the surveillance camera on our behavior, which, of course, was the evidence that a mental or cognitive act had occurred. The interpreter not only took note; it tried to make “sense” out of the behavior by keeping a running narrative going on about why a string of behaviors was occurring. It is a precious device and most likely uniquely human. It is working in us all the time as we try to explain why we like something or have a particular opinion, or rationalize something we have done. It is the interpreter device that takes the inputs from the massively modularized and automatic brain of ours and creates order from chaos. It comes up with the “makes sense” explanation that leads us to believe in a certain form of essentialism, that is, that we are a unified conscious agent. Nice try, interpreter! "

" Amid great anticipation, Giacomo slowly lowered the electrode into the callosum. As is commonly done in neurophysiology, the recording system was hooked up to a loudspeaker so that the rat-tat-tat of the neurons firing could be heard. We were ready to hear the Morse code of the brain.
Then it happened. The electrode pierced the callosum. Instead of the rat-tat-tat we expected, the loudspeaker boomed with the excruciatingly clear voice of Ringo Starr singing, “We all live in a yellow submarine, a yellow submarine, a yellow submarine.” Giacomo looked up from the cat and calmly said, “Now that is what I call high-order information.” Some kind of electronic ground loop had been closed, and we were picking up the local radio station. We all laughed, though we knew this brain code thing was going to be a long haul. "
