"It is comparatively easy to measure the thresholds that our brain uses to create temporal structure, i.e. the minimum time interval required to correctly tell apart the sequence of brief sounds or images," he writes--that's measured in the milliseconds. Read the rest
My cousin Katherine Leipper is part of a crew that's building a 15-foot-tall head and brain with interactive light and flame effects that will be controlled by a participant's brain waves.
Yup. Weirdness runs in our family.
She and her co-makers will take it to Burning Man, but the bigger plan is to take it around to schools after the festival, "to get kids excited about science, technology and fabrication."
Katherine and her brain-building buddies have a crowdsourcing campaign under way. They're well on their way, but if you love 15-foot-tall brain-controlled brains like I love 15-foot-tall brain-controlled brains, and you think America's children need more 15-foot-tall brain-controlled brains in their classrooms because SCIENCE, you should kick in a little to ensure this weird dream comes true.
Katherine explains the wild idea to Boing Boing, below: Read the rest
Neuroscientist have attached an electronic "backpack" to dragonflies that jack into the insect's brain and wirelessly transmit the data back to a base station. Howard Hughes Medical Institute researcher Anthony Leonardo and his collaborators hope the telemetry will deepen our understanding of how dragonflies target and catch their pray.

In 1961, Mel Blanc, the voice of Bugs Bunny, Porky Pig, Barney Rubble, and literally a thousand other cartoon characters (see vide above), was in a terrible car crash that put him in a coma. Nothing could rouse him until his surgeon addressed him as Bugs Bunny. Of course, Blanc's response was: "What's up, Doc?" Here's a 2012 short episode of Radiolab where they interview the surgeon, a neuroscientist, and Mel Blanc's son, Noel.

I have a personal Facebook account, which I use to keep up with friends and family. Like many of you, I've also discovered that this gives me a peek inside the psyche of those friends and family — and one of the things that I saw was an interest (and sometimes belief in) conspiracy theories. It wasn't limited to the Right or the Left. And it definitely wasn't limited to people I love but consider a little "off", if you know what I'm saying.* Over and over, I saw perfectly rational, sane people, supporting and spreading ideas that, to me, seemed a little nuts.
And that made me curious: Where do conspiracy theories come from? The answer, according to psychologists and sociologists, is not "Glenn Beck's fevered imagination." In fact, the category "people who believe in conspiracy theories" can't even really be separated into The Other in a nice, neat way. If you look at the data, the people who believe in conspiracy theories are us. And those theories grow out of both historical context, our feelings about ourselves and the wider world, and the way that our brains respond to feelings of powerlessness and uncertainty. Here's a short excerpt from my most recent column for The New York Times Magazine:

While psychologists can’t know exactly what goes on inside our heads, they have, through surveys and laboratory studies, come up with a set of traits that correlate well with conspiracy belief. In 2010, Swami and a co-author summarized this research in The Psychologist, a scientific journal.
I've written before about Moran Cerf -- celebrated neuroscientist, former military hacker, and good-guy bank robber -- who also happens to be a great storyteller. Here's a video in which Cerf recounts some clever and fascinating neuroscience experiments that use neurofeedback to help people resolve competition between different thoughts and wills in their minds. The applications are even more interesting -- mentally controlling a robotic arm, for example.
