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
Dopamine — the most talked-about human neurotransmitter — isn't a "love drug", or a "lust drug", or an "addiction drug", writes Bethany Brookshire in a smarter-than-average neuroscience story
at Slate. It's actually a lot more complicated than that, and if you keep trying to pigeonhole and oversimplify what it does, you're going to completely misunderstand how your brain works. Read the rest
Scientists are trying to understand "cuteness agression"
— aka, the urge we have all felt, at one point in time or another, to take something adorable and squeeze it until it pops. 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.

Insights on science and doing science by the woman who studied one of history's most famous neuro patients.
In general, they seem to like it. But with reservations.
The Obama Administration's highly touted brain-mapping program — pitched as a neurological analog to the Human Genome Project — might be approaching the problem of how the brain works in the wrong way. In particular, if the Initiative only focuses on mapping activity in the brain, it's going to miss out on the ways activity and neural architecture work together to create a functioning system.

Scientists managed to link the brains of a conscious human and an anesthetized rat

Here are a couple different perspectives on the big news out of Washington this afternoon — an ambitious Obama Administration proposal to appropriate $100 million to begin a project to "map the brain". What's that mean? We have a lot of good data on single neurons. We have a lot of good data on what happens in the brain, as a whole, during certain tasks. What we don't really understand is how those individual neurons work together as networks or what activity in the brain really means on the level of causality and processing. That's what this project would be aimed at understanding. At LiveScience, Stephanie Pappas puts the project into scientific (and financial) context

"Mounting evidence shows that many people with dyslexia are highly creative, out-of-the-box thinkers, and neuroimaging studies demonstrate that their brains really do think differently." An interesting piece in the Wall Street Journal

This review also appears on Download the Universe, a group blog reviewing the best (and worst, and just "meh") in science-related ebooks and apps.
When I go to science museums, I like to press the buttons. I'm convinced this is a special joy that you just do not grow out of. Hit the button. See something cool happen. Feel the little reward centers of your brain dance the watusi.
But, as a curmudgeonly grown-up, I also often feel like there is something missing from this experience. There have definitely been times when I've had my button-pushing fun and gotten a few yards away from the exhibit before I've had to stop and think, "Wait, did I just learn anything?"
Science museums are chaotic. They're loud. They're usually full of small children. Your brain is pulled in multiple directions by sights, sounds, and the knowledge that there are about 15 people behind you, all waiting for their turn to press the button, too. In fact, research has shown that adults often avoid science museums (and assume those places aren't "for them") precisely because of those factors.
Sound Uncovered is an interactive ebook published by The Exploratorium, the granddaddy of modern science museums. Really more of an app, it's a series of 12 modules that allow you to play with auditory illusions and unfamiliar sounds as you learn about how the human brain interprets what it hears, and how those ear-brain interactions are used for everything from selling cars to making music.

Many years ago I watched a standup comic on television explain that the President of the United States has no more control over the country than the bulldog hood ornament on a Mack Truck has in controlling where the truck goes. He was exaggerating but he had a point.
Neuroscientist David Eagleman has a similar argument about the human brain. Our conscious brain (our "I") is the tiny chrome bulldog, while our non-conscious brain is doing the driving. His highly-readable pop science book, Incognito: The Secret Lives of the Brain, offers dozens of persuasive examples to support the idea that our conscious brain is at the tip of our behavioral iceberg.
Here's a few questions Eagleman asks in Incognito:
Why can your foot jump halfway to the brake pedal before you become consciously aware of danger ahead? Why do strippers make more money at certain times of month, even while no one is consciously aware of their fertility level? Is there a true Mel Gibson? What do Odysseus and the subprime mortgage meltdown have in common? How is your brain like a conflicted democracy engaged in civil war? Why are people whose name begins with J more likely to marry other people whose name begins with J? Why is it so difficult to keep a secret? Why did Supreme Court Justice William Douglas deny that he was paralyzed?
Eagleman's answer to all of these questions is that the non-conscious brain is made up of many signal processors, honed by eons of evolution, that compete and cooperate with each other to make decisions that eventually make their way to the tip of the cognitive iceberg, where the "I" takes credit.

There is no such thing as "left brained" or "right brained". You really and truly cannot break down rationality and creativity in that way. And that's not the only thing we all think we know about the brain that turns out to be totally wrong. At the Guardian Vaughan Bell writes about the rise of folk neuroscience, why these misconceptions are actually problematic, and which bits of false information we need to stop repeating to one another
