As a child of the Sixties, I have been imbued with the music of the time. Somewhere in my brain there is a virtual juke box, where songs and memories are inextricably intertwined. Without forewarning, an event or thought will flip a switch; then, traveling through the synapses in my brain, a tune will come to mind; and–much like Doris Day in a 1950s musical–I will break out into song. It is, so to speak, a very emergent phenomenon. Of late, for example, it is the tune Going Out of My Head by Little Anthony and the Imperials that keeps running through my mind.

This notion of the virtual juke box came to mind, I think, because I have been exploring how the brain works in my class Networks and the Creative Process. Most stimulating in triggering my thoughts about how the brain, memories, and every day experiences are linked together has been Joseph Le Doux’s book Synaptic Self: How Our Brains Become Who We Are –a book I highly recommend. In this book, Le Doux raises the question of how we evolve to become the persons we are.

how do we evolve to become the persons we are

Le Doux’s narrative relates to the eternal debates–dating back at least to the time of Plato and Aristotle–about the mind-body problem. Le Doux transcends this dichotomy, arguing that the body (brain) and mind (soul, consciousness, self) are one. The brain, according to Le Doux is constituted of a complex network of neurons that house genetic information and memory. While these neurons store information, they are continually upgraded via axions and dendrites that reach out from other parts of the network, transmitting information via neurotransmitters, such as seritonin and dopamine. As Le Doux explains, all individuals have a brain structure that replicates this pattern, but it is an individual’s specific architecture–the product of genetic makeup and experience–that makes him or her unique. As he says: we are our synapses.

So, reading Le Doux, it is now clear to me that my virtual juke box is just one customized circuit among the millions of circuits that make up my brain. Moreover, I can see how this circuit has evolved and accompanied me throughout my life, housing all the songs that have buffered me through my first heart-breaks, the anti-war movement, and all those difficulties associated with the rebellious Sixties. But why now, I ask, should the song Going out of My Head–a song I haven’t thought about in years–suddenly raise its head.

A few weeks ago I heard a colleague speak to a group of students. Talking about his own intellectual journey, he described in a most poignant way his decision to pursue what he characterized as a Life of the Mind. Shades of Plato. Having just read Le Doux, I had to question his words. If the mind is the sum total of all our synapses, isn’t Living the Life of the Mind what we all seek to do? As for me, were I to be constrained to work with only one part of my brain, I think I would go out of my head.
