Fantasyland: Author Kurt Andersen

Above Video: Center for Inquiry / How can we make sense of America’s current “post-factual,” “post-truth,” “fake news” moment? By looking to America’s past. All the way back. To the wishful dreams and make-believe fears of the country’s first settlers, the madness of the Salem witch trials, the fantasies of Hollywood, the anything-goes 1960s, the gatekeeper-free internet, the profusion of reality TV….all the way up to and most especially including President Donald Trump. In this fascinating and lively talk, Kurt Andersen brings to life the deep research behind and profound implications of his groundbreaking, critically acclaimed and bestselling latest work.

The mysterious nature of music

By Steve Rensberry  

   What is music?
   A world beyond time?
   A refuge for the heart in a world of longing and uncertainty?
   A synthesis of mind, body and soul?
   "What is the secret of music's stranger power? Seeking an answer, scientists are piercing together a picture of what happens in the brains of listeners and musicians," reads the subhead to an article by Norman Weinberger entitled Music and the Brain, published by Scientific American in 2004.
   What lies at the heart of music's ubiquitous nature? How exactly does it move us? Weinberger asks.
   His summary findings: "Overall, findings to date indicate that music has a biological basis and that the brain has a functional organization for music. It seems fairly clear, even at this early stage of inquiry, that many brain regions participate in specific aspects of music processing, whether supporting perception (such as apprehending a melody) or evoking emotional reactions. Musicians appear to have additional specializations, particularly hyperdevelopment of some brain structures."
   Associated Press Science Writer Malcolm Ritter looks at another aspect to the issue in the article, Study: Love music? Thank a substance in your brain, which points to new research suggesting one specific reason for humanity's undying and historic attraction to music.
   "Whether it's the Beatles or Beethoven, people like music for the same reason they like eating or having sex: It makes the brain release a chemical that gives pleasure," Ritter says in regard to the new study.
   That substance, in case you're wondering, is dopamine.
   Real-time brain scans of people as they were listening to music revealed another interesting fact: The effect was immediate and direct.
   "PET scans showed the participants' brains pumped out more dopamine in a region called the striatum when listening to favorite pieces of music than when hearing other pieces. Functional MRI scans showed where and when those releases happened," Ritter says.
  Nevertheless, while recent research gives us a glimpse into the complex effects of music on the human brain, the verdict remains out on a number of fundamental questions, namely: What is music? Does it have meaning? And what exactly is its evolutionary or metaphysical purpose?
   There are a number of theories, but none so far appears to be definitive.
