Humans Already Use Way, Way More Than 10 Percent of Their Brains -It’s a complex, constantly multi-tasking network of tissue—but the myth persists.  - By now, perhaps you’ve seen the trailer for the new sci-fi thriller Lucy. It starts with a flurry of stylized special effects and Scarlett Johansson serving up a barrage of bad-guy beatings. Then comes Morgan Freeman, playing a professorial neuroscientist with the obligatory brown blazer, to deliver the film’s familiar premise to a full lecture hall: “It is estimated most human beings only use 10 percent of the brain’s capacity. Imagine if we could access 100 percent. Interesting things begin to happen.” Johansson as Lucy, who has been kidnapped and implanted with mysterious drugs, becomes a test case for those interesting things, which seem to include even more impressive beatings and apparently some kind of Matrix-esque time-warping skills. Of course, the idea that “you only use 10 percent of your brain” is, indeed, 100 hundred percent bogus. Why has this myth persisted for so long, and when is it finally going to die?

Love is the drug, scientists find -Cambridge University scientists find that those with drug addiction and sex addiction have similar neurological responses  - When Roxy Music star Bryan Ferry declared that ”love is the drug” he may have been speaking the truth. Cambridge University scientists have found that sex and drug addiction may be two sides of the same neurological coin. When diagnosed sex addicts looked at explicit sexual images, it triggered brain activity very similar to that seen in people dependent on drugs. But the researchers caution that this does not suggest pornography is generally addictive. Lead scientist Dr Valerie Voon, from Cambridge University, said: ”The patients in our trial were all people who had substantial difficulties controlling their sexual behaviour and this was having significant consequences for them, affecting their lives and relationships. ”In many ways, they show similarities in their behaviour to patients with drug addictions. We wanted to see if these similarities were reflected in brain activity, too. ”There are clear differences in brain activity between patients who have compulsive sexual behaviour and healthy volunteers. These differences mirror those of drug addicts.” Previous studies have suggested that up to one in 25 adults may be affected by an obsession with sexual thoughts, feelings or behaviour they are unable to control. Public awareness of sex addiction has been raised by celebrities seeking help for the problem, including actors Michael Douglas and David Duchovny. The Cambridge scientists recruited 19 male sex addicts and played them short videos featuring either explicit pornographic scenes or people engaged in exciting sports such as skiing or skydiving. At the same time, the men’s brain activity was monitored using a functional magnetic resonance imaging (fMRI) scanner. The experiment was repeated with a matched group of volunteers not affected by sex addiction. Three regions of the brain were found to be especially more active in the brains of the sex addicts than in the healthy volunteers, the ventral striatum, dorsal anterior cingulate and amygdala. All three are also known to be activated in drug addicts stimulated by the sight of drug-taking paraphernalia. (via Love is the drug, scientists find - Telegraph)

While most of us go through life feeling that we are the thinker of our thoughts and the experiencer of our experience, from the perspective of science we know that this is a distorted view. There is no discrete self or ego lurking like a minotaur in the labyrinth of the brain. There is no region of cortex or pathway of neural processing that occupies a privileged position with respect to our personhood. There is no unchanging “center of narrative gravity” (to use Daniel Dennett’s phrase). In subjective terms, however, there seems to be one — to most of us, most of the time. Our contemplative traditions (Hindu, Buddhist, Christian, Muslim, Jewish, etc.) also suggest, to varying degrees and with greater or lesser precision, that we live in the grip of a cognitive illusion. But the alternative to our captivity is almost always viewed through the lens of religious dogma. A Christian will recite the Lord’s Prayer continuously over a weekend, experience a profound sense of clarity and peace, and judge this mental state to be fully corroborative of the doctrine of Christianity; A Hindu will spend an evening singing devotional songs to Krishna, feel suddenly free of his conventional sense of self, and conclude that his chosen deity has showered him with grace; a Sufi will spend hours whirling in circles, pierce the veil of thought for a time, and believe that he has established a direct connection to Allah. The universality of these phenomena refutes the sectarian claims of any one religion. And, given that contemplatives generally present their experiences of self-transcendence as inseparable from their associated theology, mythology, and metaphysics, it is no surprise that scientists and nonbelievers tend to view their reports as the product of disordered minds, or as exaggerated accounts of far more common mental states — like scientific awe, aesthetic enjoyment, artistic inspiration, etc. Our religions are clearly false, even if certain classically religious experiences are worth having. If we want to actually understand the mind, and overcome some of the most dangerous and enduring sources of conflict in our world, we must begin thinking about the full spectrum of human experience in the context of science. But we must first realize that we are lost in thought.
