Fleeting images of fearful faces reveal neurocircuitry of unconscious anxiety
New York – Researchers at Columbia University Medical Center have found that fleeting images of fearful faces – images that appear and disappear so quickly that they escape conscious awareness – produce unconscious anxiety that can be detected in the brain with the latest neuroimaging machines.

I believe thsi may interest you Mr Houston, Neuro-linguistic programming (NLP) is a field of human endeavor concerned with empirically studying and modeling human performance and excellence, with the goal of creating transferable skill sets. en.wikipedia.org/wiki/Neuro-linguistic_programmingFreaky or what?

Thanks Meph, That's facinating. Right up my street as well! Used to have a book on the subject but I didn't get a chance to read it before I misplaced it.
Anyway Have a nice xmas mate!

Study disputes randomness of dreams
New research shows aggressive and emotionally charged dreams tend to occur in the early stages of REM sleep and calmer dreams occur later. Science has long been occupied with understanding our unconscious, and what is really going on when we dream. Now, a study of dream and sleep state activity has revealed that when we dream it's usually about social interactions, and that our emotional state in those interactions - whether we're friendly or aggressive - varies predictably depending on the stage of sleep we're in.

Eye cell research. "Experts feel that the discovery will lead to being able to restore black and white light sensitivity, and it would also lead to new cures for conditions such as sleep, insomnia, depression and seasonal affective disorder". www.femalefirst.co.uk/health/1612004.htmMeph

Scientists Switch Stem Cells into Neurons Scientists have long been studying the process of how mammalian stem cells differentiate to form specific types of brain cells. Researchers are now reporting another small step toward understanding what conditions are necessary for spinal motor neurons to form: they have coaxed human embryonic stem cells to differentiate into one critical component of the nervous system. Su-Chun Zhang of the University of Wisconsin-Madison and his colleagues exposed human embryonic stem cells to a variety of growth factors and hormones in sequence in order to encourage them to change into motor neurons. "You need to teach the [embryonic stem cells] to change step by step, where each step has different conditions and a strict window of time," Zhang explains. "Otherwise, it just won't work." The embryonic stems cells first became neural stem cells then changed into the beginnings of motor neurons before finally differentiating into spinal motor neuron cells, the cell type that, in the human body, transmits messages from the brain to the spinal cord. The newly generated motor neurons exhibited electrical activity, the signature action of neurons, and survived in culture for more than three months. The team next plans to test the cells' ability to communicate with other cell types after they are transplanted into developing chickens. Tests on humans, however, remain years in the future, Zhang cautions. But the findings could still prove useful for people: Zhang posits that motor neuron modeling systems in the laboratory could be used as proxies to screen potential new drugs. The results were published online today by the journal Nature Biotechnology. --Sarah Graham www.sciam.com/article.cfm?chanID=sa003&articleID=00048F8A-C91A-11FA-891A83414B7F0000

A genius explains Daniel Tammet is an autistic savant. He can perform mind-boggling mathematical calculations at breakneck speeds. But unlike other savants, who can perform similar feats, Tammet can describe how he does it. He speaks seven languages and is even devising his own language. Now scientists are asking whether his exceptional abilities are the key to unlock the secrets of autism. Interview by Richard Johnson www.guardian.co.uk/weekend/story/0,,1409903,00.html Meph
