... would love to take part in a scientific brain experiment.

So, how many subjects are there in a split brain? I know that at least one more mefi user is interested. To get some background information, play this little game from nobelprize.org. Personally, I think they (even though the layout is strange - for an edu site) have it right: [more inside]

Switching off self-awareness

Researchers have found that prolonged concentration on a difficult task actually switches off a person's self awareness. Fancy experiencing this sensation for yourself? That would be an oxymoron in existence. Just lay back and let the orgasm take hold.

singularity gets just slightly closer

Italian & German researchers have created a "neuro-chip" for linking computers with mammalian neurons (A NewScientist, LiveScience, MSN). They added neuron gluing proteins to the chip to attract the sodium pores, and genetically modified the neurons to add more sodium pores.

In the short term, the work is expected to aid the pharmaceutical industry in testing the effects of drugs on neurons, assist basic research into the workings of the brain, and perhaps help treat neurological disorders. In the long term, numerous sci-fi technologies are slightly closers, such as computers with living components, useful brain implants, and Beowulf clusters of humans.

MIT researchers play Borg God

New hope for blind hamsters. According to the Guardian, scientists at MIT have repaired brain damage and restored eyesight to rodents using nanotechnology. In the study, minute particles were injected into damaged parts of the brain, and subsequently arranged themselves into a "scaffold" gel throughout the damaged area. The scaffold allowed severed nerves to regrow and form new connections. 75% of test animals' injuries were improved with the new technique. (The article did not note if the test subjects offered any resistance to the therapeutic measures.)

Mind control

Typing with your brain. A new device, picture d here, allows people to type with only their thoughts, though only slowly. Add this to the monkey-brain controlled robot arm (avi), and the soon-to-be commercially available BrainGate implant, [previously], and you've got, well, an interesting future...

The Reinvention of the Self

Neurogenesis Neurogenesis, the birth of new brain cells, was something we were all taught was impossible after a certain point. Professor Elizabeth Gould, doctor of psychology at Princeton, has claimed that it happens all the time. (more) Now, she and her team at Princeton are saying not only is our brain always changing, stress and environment directly affect brain development.

Henry's Brain

The strange story of Henry M. Henry was able to hold information in storage for very short periods of time. Most people can retain about seven pieces of information (a telephone number, for example) in memory for about thirty seconds, and Henry scored normally on these kinds of tasks. Thus, his working memory (or scratch-pad memory) seemed unaffected by the loss of his hippocampus. The main problem for Henry was converting short-term memories into permanent storage, a process called consolidation. Henry's case is one of the most studied brain-damage cases [PDF] ever. A fascinating story about one man's struggle with brain surgery.

Cancel MetaFilter

Political thinking isn't really 'thinking'. Neuroscientists have now tracked what happens in the politically partisan brain when it tries to digest damning facts about favored candidates or criticisms of them. The process is almost entirely emotional and unconscious, and there are flares of activity in the brain's pleasure centers when unwelcome information is being rejected. Via Slate. This jives with past research about the difference between democrat’s and republican’s brains.

Don't Even Think About Lying

Don't Even Think About Lying fMRI is poised to transform the security industry, the judicial system, and our fundamental notions of privacy. I'm in a lab at Columbia University, where scientists are using the technology to analyze the cognitive differences between truth and lies. By mapping the neural circuits behind deception, researchers are turning fMRI into a new kind of lie detector that's more probing and accurate than the polygraph, the standard lie-detection tool employed by law enforcement and intelligence agencies for nearly a century.

Better living through MIND CONTROL

ESB (Electrical Stimulation of the Brain) can be used to create feelings of intense euphoria and (in some unintentional cases) paranoia. Since we don't know too much about what's inside our skulls, to what extent should we be allowed to control it?

The concept of the Transhuman: human, the self, consciousness and their effects on the law

The first Transhuman Conference On the Law of Transhuman Persons: Whether or not you believe humans are set to evolve into gods, or AI is destined to achieve self-awareness the idea of the Transhuman is a thought provoking concept. Philosophers have debated the nature of the self, of the human for millennia. Is it time to start drafting new laws to govern all possible sentient beings on this planet? or is it all just a science of fiction? a comfortable humanist illusion?

The Anorexia Debate: Biology v Culture

A recent study of 60 people with anorexia suggests that a biological mechanism may be a causative factor. It was found that there was a reduction in blood flow to a specific area in one of the temporal lobes in those with the eating disorder. The author of the study believes that sociocultural factors have been over emphasized. Not all agree. By way of contrast, another research group has just published findings which purport to show that "even small amounts of exposure to thin bodies can have a short-term negative effect on body image." And adult anorexia rates are said to be rising.
There's associated debate too, regarding the contributing role played by therapy that seeks to personify eating disorders. Flourishing underground online communities derive some thinspiration by referring to their 'lifestyle choices' as 'Ana' (for anorexia) and 'Mia' (for bulimia). Argentina is responding to the body image controversy by enacting a size law. previous mefi threads [via + via ]

Ramachandran for brain enthusiasts

Phantom limb illusions Dr. Ramachandran is an investigator of the senses. His explorations on synesthesia, phantom limbs, and human consciousness are revealing excursions into sensory awareness. And his reader-friendly books, such as A Brief Tour of Human Consciousness and Phantoms in the Brain (both from Amazon) are a pleasure to read. His greatest gifts appear to be a childlike simplicity, coupled with straightforward empiricism. His writing is easy-to-understand, often sparked with unpredictable humor. Recommended for all mind & brain enthusiasts who may not have heard of him yet.

Gender Based Brain Research

A review of the current state of gender based brain research shows that women and men differ both in the way their brains are constructed and in how they function.
..correlation between brain region size in adults and sex steroid action in utero suggests that at least some sex differences in cognitive function do not result from cultural influences or the hormonal changes associated with puberty--they are there from birth.
Treatment for such things as schizophrenia and depression will likely have gender specific variations in the future. Previously, brain research that examined gender differences was considered controversial because it was argued that the results might give rise to more sex discrimination against women. That view may be changing. posted by peacay on May 3, 2005 - 33 comments

White Matter and Gray Matter a Matter of the Sexes

She may not have the grey matter, but what's that matter anymore, anyway? A recent study shows that men have more gray matter, women have more white matter and in the end these differences seem to be no matter. Apparently men have more raw computing power, while women have a more efficient infrastructure -- resulting in similar general intelligence.
