Aural Illusion

I'm guessing this is an example of top down processing (click that link to the left, it's a great explanation of TDP).

First, watch and listen to the video below.



Sounds sort of like "dada dada dada."

Now close your eyes and play it.

It switches to "baba baba baba." Not sure this works for everyone, but it did for me. My guess is seeing the hippie guy mouth the pronunciation of a "da" sound actually changes your perception of the sound. Close your eyes, and your hear the actual sound being made. The visual information is tricking your auditory perception. It's not an extraordinary example of top down processing, but it's pretty interesting.

How to Nap

Really informative little graphic in the Boston Globe on how to nap.

Look! No Hands!

Here's a video clip of a guy navigating his Second Life Avatar with his brain. It is speculated that this could help people with Locked-in Syndrome, a rare affliction that was the topic of "The Diving Bell and the Butterfly," written by Jean-Dominique Bauby. This would potentially allow these people to communicate more effectively - certainly more so than Bauby's pain-staking process:

"The entire book was written by Bauby blinking his left eyelid - in July and August of 1996. A transcriber repeatedly recited a French language frequency-ordered alphabet (E S A R I N T U L etc.), until Bauby blinked to choose the next letter. The book took about 200,000 blinks to write and each word took approximately two minutes"

Can't Get That Song Out of Your Head?

Listen to the whole thing, apparently...interesting, if not a bit counter-intuitive...

"Getting "Eye of the Tiger" stuck in your head is the result of a glitch in your auditory cortex. This part of your brain processes sounds and stores them for later recall. It powers up and can start crooning uncontrollably after hearing just a few notes of a familiar tune. Want it to stop? Listen to the whole song or do some math"

Why would you ever want Eye of the Tiger out of your head? I'd be more concerned if it was, "near... far...whereEVER you are..."

Is it in your head now? It's in mine. So I have to go listen to the whole damn song? Not sure I'm happy with this solution...

To digress, the way we describe brain processes still sounds screwy to me. The idea of "powering up" areas of the brain paints an over-simplified and inaccurate picture.

In Entertainment News...

Dr. Drew Calls Tom Cruise "mentally ill." I can't say I'm a HUGE Dr. Drew fan, but sometimes he comes out with gems like this:

"A lot of people in the public eye who behave strangely have mental illness we can learn from, and much of it is based on childhood trauma, without a doubt. Take a guy like Tom Cruise. Why would somebody be drawn into a cultish kind of environment like Scientology? To me, that's a function of a very deep emptiness and suggests serious neglect in childhood - maybe some abuse, but mostly neglect."

To a lot, this probably sounds like psychobabble, but from my experience, and based on what I've learned from the few the really good psychiatrists I've met (all one of them) - abuse and neglect are the main culprits for futurepathological behavior. It is NOT chemical imbalances and neurological disorders - that's a pharmaceutical fantasy...

Smoking Cessation Drug = Life Cessation

This one just blows me away. Have you tried the Chantix to quit smoking? Yet another SSRI on the market to treat any old condition (smoking, despression, obesity, social anxiety - what's the difference?)

Here's a new catch, the drug has been banned for truck drivers, pilots, and traffic controllers due to its side effects (another example of the odd movement disorders associated with SSRI's). According to the Wall Street Journal's Health blog:

"More than 100 traffic or personal accidents, like falling, have been linked to Chantix in a recent study by outside researchers; their figures came from in the FDA’s adverse events database. One hypothesis is that convulsions, blackouts, seizures or spasms could have contributed to such incidents."

I read one account about a guy driving his truck while on Chantix and crashed into a bayou:

"His girlfriend, Melinda Lofton, who was with him, later told him that his eyes had rolled back in his head and that it had seemed as if he was frozen at the wheel, accelerating."

That one really spooked me. God, I need a cigarette...

"Brain Downloads" Are Not Going to Happen

Nice to see Neurophilosophy agrees with me on this one. Here's a totally stupid and uninformed article on why "brain downloads 'will make [school] lessons pointless.'"

Just recently, I wrote a post about why this is impossible (in the context of Dr. Daniel Carlat's Wired article on brain scans), it seems the progressive ideas of the Matrix are far too pervasive in our culture.

"I think people will be able to directly access, Matrix-style, all the vocabulary you need for a foreign language, leaving you just to clear up the grammar."

This amazingly asinine quote comes from the guy steering curriculum for 1300 private schools in the UK. Best of luck with that, stupid...



Not quite, Neo...
