Mind Matters by Michael S. Gazzaniga

The famous Berkeley psychologist David Krech once made the observation, “There is no phenomenon, however complex, which when examined carefully will not turn out to be even more complex.”
Mind Matters (page 175)

How much has our understanding of brains progressed since the publication of this popular science book in 1988? Maybe a little, but many studies serve to reveal effects without shedding light on their causes, or otherwise uncover new unknowns. Complete understanding of the connection between the brain and the mind, and the mind/brain’s connection to the body, will, I think, always be just over the horizon, like world peace, the cure for cancer, and flying cars—especially if we keep talking about brains as computers (which Gazzaniga does in the first paragraph of his introduction), but that’s another story.

Meanwhile, brain scientist Michael S. Gazzaniga offers his thoughts, informed by his professional experience, on twelve relatable subjects:

  1. Pain
  2. Memory and Thinking after Forty
  3. Intelligence
  4. Crazy Thoughts
  5. Anxiety
  6. Depression
  7. Obsessions and Compulsions
  8. Addiction
  9. Love
  10. Sleeping and Dreaming
  11. Stress
  12. Healing

It’s an interesting bunch of topics. The chapter on addiction was surprisingly political. Gazzaniga makes a case for legalizing drugs (and taxing them) to prevent the harms that arise from black markets (and funding programs for treatment of addiction). He says addiction is not the sort of thing that can snowball into an epidemic. From his standpoint, some small, stable percentage of people will inevitably be addicts; meanwhile everyone else is pretty much okay.

Gazzaniga’s writing is informed in part by his work on split-brain studies. Ever heard about those? Some epileptics have undergone surgery to disconnect the two normally connected brain hemispheres to reduce the occurrence of debilitating seizures. Studies conducted on such subjects involve presenting a picture or instructions to only one half—the left half—of the visual system (thus to only one half—the right half—of the brain). The result is spurious explanations supplied by the left half, which controls language, for the individual’s response. Somewhere in the left half of the brain is a mind module that really wants things to make sense, even when they don’t. Gazzaniga calls this module “the interpreter”.

The book offers a framework that considers both psychology and neurobiology in explaining “a wide variety of very personal mind states we all experience at one time or another.” It acknowledges individual differences due to brain development as well as genetic influences on brain chemistry.

I’m looking forward to reading a more recent book by Gazzaniga: The Consciousness Instinct.
