brain
edyong | March 5, 2008Modern brain-scanning technology allows us to measure a person's brain activity on the fly and visualise the various parts of their brain as they switch on and off. But imagine being able to literally see what someone else is thinking - to be able to convert measurements of brain activity into actual images.
It's a scene reminiscent of the 'operators' in The Matrix, but this technology may soon stray from the realm of science-fiction into that of science-fact. Kendrick Kay and colleagues from the University of California, Berkeley have created a decoder that can accurately work out the one…

Chimpanzees may not be able to recite Hamlet or giving rousing speeches but there is no doubt that they are excellent communicators. They exchange a wide variety of sophisticated calls and gestures that carry meaning and can be tailored to different audiences.
The sophistication of chimp communication doesn't stop there. Jared Taglialatela from the Yerkes National Primate Research Center has found that chimp signals and human speech are both strongly influenced by the same area in the left half of the brain - a region called the inferior frontal gyrus (IFG).
In humans, the left IFG is home…
ddobbs | February 27, 2008A jazz player's brain: Brain activation while improvising. Blue areas are deactivated comparable to normal, orange and read are ramped up. From PLOS One.
An intriguing finding: While improvising, jazz players seem to turn OFF the part of the brain that (to quote a new study just published in PLOS One) "typically mediate self-monitoring and conscious volitional control of ongoing performance." They're in what athletes call the zone, where they navigate the oncoming musical terrain by a sort of flexible trained instinct, like boulder-hopping downhill: Think about it and you stumble. Lovely…

The 23rd edition of the Brain Blogging carnival is now available for you to enjoy. And hey, they included one of my pieces!
sb admin | December 14, 2007In a parody of Make Magazine projects, Austrian group Monochrom demonstrate how to create a brain computer interface, a.k.a. braicin, using household materials like duct tape, old ice skates, a vintage calculator, and onions in alcohol ("preferably Romanian"). Via Boing Boing TV. Link to extended director's uncut version (shown here).

The 37th edition of Encephalon is now available for your reading pleasure. The editor included a submission from me, so of course, I am happy!
bleimanb | December 3, 2007Humans are now one large step closer to producing armies of undead, zombie hordes who live only to feast on the brains of the living and reproduce by infecting non-zombies with their "zombie virus" through their saliva or other bodily fluids. This is thanks to the work of a team of scientists at Ben-Gurion University of the Negev in Israel, who have documented a kind of wasp that zombifies cockroaches.
Ampulex compressa enjoys licking pieces of wood, long walks on the beach and necromancy.
The Ampulex compressa actually stings a roach twice, once to disable it, and again (this time…

Now that the school year has started again, I think it is worthwhile to repeat an earlier blog entry where I linked to a really interesting interactive game, called Mouse Party. This interactive game is a great educational tool, teaching you how various legal and illegal drugs work in the brain.
Have you ever wondered how various drugs work in the brain to produce the symptoms they do? Well, this wonderful interactive website, Mouse Party, shows you the molecular details of how heroin, exstacy, alcohol,…

Look Around You: Brain. "The brain is basically a wrinkled bag of skin filled with warm water, veins, and thought muscles. ... The opposite of the brain is probably the bum." Brief vintage BBC parody of science education films about the brain. Watch through to the end, when a brain in a jar is rewarded with a special treat for performing a task.
grrlscientist | October 9, 2007The 33rd edition of Encephalon was just published and they included one of my essays. As you might remember, I hosted the previous edition of Encephalon so be sure to visit this issue as well!

The last frontier: The brain.
Orphaned Image. Contact me so I can provide credit and linkage.
Several months ago, I was invited to host Encephalon, probably because I send so many submissions to this blog carnival and possibly also because I am fairly good at sending traffic to the contributors of those blog carnivals that I host. Unfortunately, I have not had wifi for the past two days, so I hope that you appreciate my modest efforts on behalf of this blog carnival. So, without further ado, I present to you the 32nd…

Recent research has shown that women older than 65 years old who drink more than three cups of coffee per day were protected from some types of age-related memory declines.
"The more coffee one drank, the better the effects seemed to be on (women's) memory functioning in particular," reported Karen Ritchie, epidemiological and clinical researcher at La Colombiere Hospital and at the French National Institute of Medical Research (INSERM), in Montpellier, France.
To do this research, the researchers studied more than 4,197…

The first thing that most people think of when they hear the word "steroids" is baseball players who rely on these chemicals to increase their muscle mass and thereby improve their athletic performance. But recently, a small songbird that I studied for my dissertation work, Gambel's white-crowned sparrow, Zonotrichia leucophrys gambelii, has shown scientists that steroids trigger the growth of…
