EDW Lynch of Laughing Squid says: "Sleight-of-hand artist and master pickpocket Apollo Robbins demonstrates the art of misdirection on an unlucky volunteer in this entertaining TED talk from TEDGlobal 2013." Read the rest
If somebody tells you an ostensible fact about human behavior or human thought and shows you a picture of an fMRI at the same time, are you more likely to believe what you've just been told
? There's a debate within science right now about whether people are more easily lead astray by brain imaging, or whether those rainbow pictures of the mind affect our thinking much at all. Some studies show one result. Some show another. At Scientific American Mind, Jay Van Bavel and Dominic Packer explain why both sides might be right in this fight. It's a neat reminder that answers aren't always binary. Read the rest
The artificial sweetener Splenda was discovered
when a chemistry grad student misunderstood his advisor's instructions to "test" a compound and tasted it, instead. (This piece at Scientific American focuses on how the brain responds to, and is changed by, sweeteners.) Read the rest
If you look at this wheel out of your peripheral vision, you should see it flicker or strobe a bit. (To me, it almost looks like a fast pulsating motion, coming from the center of the wheel.) And that's neat. Optical illusions are usually pretty neat.
But, as the blogger Neuroskeptic writes, there's some reason to think that what you're seeing might be something even more awesome than just your brain being misled. A study published this month in The Journal of Neuroscience suggests that the flickering is actually a visual representation of the rhythmic alpha waves that are constantly pulsating through your brain.

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
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.
The complicated process
that allows your brain to quickly cancel an order and replace it with another. Read the rest
Jalees Rehman has an interesting neuroscience essay on 3Quarksdaily
about the three second rule of temporal perception and processing in the human brain.
"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
Neuromarketing is one of those ideas that might best be classified as "important and creepy, if true,"
writes Matt Wall at Slate. Fortunately for us, there's not really much evidence that marketing professionals can use fMRI data (or any other neuroscience tools) to manipulate us into buying stuff. Nor can they get unique glimpses of our subconscious desires. In the end, there's not much neuro happening in this mini-industry, but there is a lot of marketing. 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
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. (via Wired) Read the rest
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.
"What's Up, Doc?" (Radiolab)

Your memories can be manipulated and changed
. In fact, this happens often. And you're the one doing it to yourself. Read the rest
