Creativity is actually more than one thing, it happens in many different parts of your brain, and it is DEFINITELY NOT confined to the brain's right hemisphere. At Beautiful Minds, Scott Barry Kaufman talks about the complex processes that get glossed over in our pop-sci understanding of creative thinking
. It's a good companion to the story I wrote here last week
about why the idea of "fear" is also more complex than we give it credit for. Read the rest
Moheb Costandi has written two amazing profiles
on psychologist Elizabeth Loftus
, a researcher who has challenged the way we rely on memory in the courtroom and fought against attempts to legitimize "recovered" memories. Hugely controversial — she's received death threats from people who blame her for setting criminals free — Loftus' story isn't purely about science vs. emotion. In fact, Costandi writes, in her efforts make our concept of memory more evidence based, Loftus might be glossing over the rare and the weird-but-real. Read the rest
It would take a simple experiment to prove, once and for all, what causes "brain freeze". Unfortunately/fortunately the condition isn't particularly serious, so nobody has ever gotten a grant to perform that simple study

New revelations about your brain’s so-called “fear center” explain why it’s misleading to say “this part of the brain does x”. Maggie Koerth-Baker
talks to neuroscientist Paul Whalen and learns that there’s more to fear than fear, itself.
"Baader-Meinhof phenomenon": That's the colloquial name for a funny thing that happens when your brain collides with popular culture
. You know how sometimes you'll hear about something for the first time — a new ukelele duo, perhaps, or a scientist whose work you weren't previously familiar with, or some obscure underground subculture ... Boing Boing is full of opportunities for the Baader-Meinhof phenomenon to kick in — and then, suddenly, that new-to-you thing seems to be everywhere
? That's what we're talking about. Scientists call it the frequency illusion and Pacific Standard
magazine helpfully explains how it works. Read the rest

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
. At Nature News, Meredith Wadman writes about why some scientists are wary of this plan

At Wired, Ed Yong has an incredible long-read story about the researchers who are figuring out how and why individual animals sometimes turn into groups operating on collective behavior
. That research has implications far beyond the freakish, locust-filled laboratories where Yong's story begins. Turns out, bugs and birds can teach us a lot about the brain, cancer, and even how we make predictions about our own futures. Read the rest
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.

Jess Hill has published the second part of a three-part series on what it’s like to have a brain tumor diagnosed, then surgically removed. Read: Magical Realism: From Seizure to Surgery.

Radio producer Jess Hill
, who has been working in the Middle East, wrote an account of what the experience of having a grand mal seizure was like
She wrote the post a week after the episode, and two weeks before having brain surgery to remove the tumor that caused it.
"At the time I was still having seizures every few days, and just the act of writing about the first seizure in such detail almost brought on another one," Jess explains. "I initially planned to keep this account private, but after two months, I’ve decided to share it, if only for the fact that it might be useful to others who have had or will have a similar experience."
It happened when she was in transit via plane from Yemen to Beirut.

TIL: That what we think of as "pain" is actually two different things. The most basic sense is called nociception — a non-subjective reflex that drives lots of animals to pull away from dangerous things. Pain — actual pain — is what happens after nociception, and different individuals perceive it differently under different situations. So, for example, nociception is why you jerk your hand away from a hot stove. Pain is the feeling that helps you learn not to touch hot stoves again. Oh, and also, crabs might be capable of feeling both. Read the rest
“A playful brain is a more adaptive brain,” writes ethologist Sergio Pellis in The Playful Brain: Venturing to the Limits of Neuroscience. In his studies, he found that play-deprived rats fared worse in stressful situations.
In our own world filled with challenges ranging from cyber-warfare to infrastructure failure, could self-directed play be the best way to prepare ourselves to face them?
In self-directed play, one structures and drives one’s own play. Self-directed play is experiential, voluntary, and guided by one’s curiosity. This is different from play that is guided by an adult or otherwise externally directed.
A MacArthur Fellow told me that, when he was a teenager, his single mother would drop him off at an industrial supply store on Saturdays while she ran errands. Using library books as his primary resource, he built a linear accelerator in the garage. It wasn’t until neighbors complained about scrambled television and radio signals in the hours just after school and after dinner that his “playful” invention was discovered.

The Food and Drug Administration today announced
it will require the makers of popular sleeping pills like Ambien and Zolpimist to reduce the recommended dosage in half for women, "after laboratory studies showed that the medicines can leave patients drowsy in the morning and at risk for car accidents." Women eliminate the drugs from their bodies more slowly than men. (NYT) Read the rest
