I’ve been on hiatus for quite a while, in part because of some surgery (more on that later), but I just wanted to write a quick post to point you to my latest article in tomorrow’s New York Times, about how birds can sing like cricket. It’s a wonderful example of how sexual selection can alter bodies, not for simple survival but to lure the opposite sex.

I’ve got an article in today’s New York Times about one of my perennial fascinations—musical hallucinations. One of the reasons that I find this condition so interesting is that it gives us a look under the neurological hood. Our brains do not simply take in objective impressions of the world. They are continually coming up with theories, and they test them against perceptions every moment of our waking lives. It would be impossible to test them against a complete picture of reality, because the world is simply too complex and ever-changing. Instead, the brain makes quick judgments on scraps of information, revising bad theories that don’t make good predictions or using good theories as the basis for actions. Some scientists argue that musical hallucinations are evidence that our brains even make theories about music. When we hear stray sounds, we match them to tunes in our memory, in a sort of internal game of Name That Tune. Unfortunately, some people can’t test their theories well enough, it seems, and so they wind up thinking a church choir is singing in the next room, when in fact there is only silence.

Seven years ago Reginald King was lying in a hospital bed recovering from bypass surgery when he first heard the music.
It began with a pop tune, and others followed. Mr. King heard everything from cabaret songs to Christmas carols. “I asked the nurses if they could hear the music, and they said no,” said Mr. King, a retired sales manager in Cardiff, Wales.
“I got so frustrated,” he said. “They didn’t know what I was talking about and said it must be something wrong with my head. And it’s been like that ever since.”

I’ve been fascinated by this picture since I first saw it over the weekend. It’s a hint of how we may be visualizing life in years to come.
How long can an idea stay tantalizing?
