Consciousness: Eight questions science must answer | Anil Seth | Science Consciousness is at once the most familiar and the most mysterious feature of our existence. A new science of consciousness is now revealing its biological basis. Once considered beyond the reach of science, the neural mechanisms of human consciousness are now being unravelled at a startling pace by neuroscientists and their colleagues. Here are eight key questions that neuroscientists are now addressing: 1. The brain contains about 90 billion neurons, and about a thousand times more connections between them. But consciousness isn't just about having a large number of neurons. Current hot topics include the role of the brain's densely connected frontal lobes, and the importance of information flow between regions rather than their activity per se. 2. A good way to study a phenomenon is to see what happens when it disappears. A key question now is how similar general anaesthesia is to other states of unconsciousness, such as dreamless sleep. 3. 4. 5. 6. 7. 8.
Så mycket sexigare har leksaker blivit sedan 70-talet - amelia Här är 15 leksaker från 60-70-talet och nu. Skillnaden är stor mellan hur sexiga dockorna är, hur smala ben de har och hur allt för tjejer har samma färg. 1. Den första frågan man kan ställa sig är varför allting för tjejer ska vara rosa? Möjligheten att välja annan färg på leksaker man gillar, är väldigt liten. Den Fischer-Price doktorsväska vi alla hade som små till vänster på bilden nedan. 2. 3. 4. ... med stora ögon, smala kinder och restylan i läpparna... 5. ... och ser lite farlig ut? 6. 7. ... som bara existerar i en rosa värld? 8. 9. 10. 11. 12. 13. 14. 15. 13. 14. Det är så tydligt att i dag är huvudsaken att tjejer har rosa leksaker och killar de andra färgerna. Varför den här färgfrågan har blivit så viktig bland föräldrar och barn beror bland annat på, menar Fanny Ambjörnsson i sin bok "Rosa, den farliga färgen", att det tycks vara särskilt viktigt bland barn med just genus och att det bland barn är centralt med kön. Det är så klart upp till föräldarna att köpa vad de vill.

Cops find loaded gun in Tennessee woman’s vagina: report That's no place to pack a pistol. A Tennessee woman being booked for driving with a suspended license was slapped with weapons charges after cops found a loaded gun in her vagina, The Smoking Gun reported. Dallas Archer, 19, was arrested at around 3:15 p.m. Monday and brought to Kingsport jail, where cops found the tiny gun concealed in her private parts, cops said. A female cop was performing a routine search when she noticed an "unknown object" in Archer's groin. She and another female officer then took the blond perp into the bathroom, where they discovered the 4-inch North American Arms 22LR revolver. Police said the $250 gun originally belonged to John Souther, a retired car salesman from Kingsport. Souther said it was stolen from his 1994 Mustang last year while the car was parked in front of his home. "Oh gosh," Souther, 70, told The Smoking Gun after learning where his gun was found. The "little fellow," he said, would need a "bath in bleach." Join the Conversation:
10 Psychological Experiments That Went Horribly Wrong Psychology as we know it is a relatively young science, but since its inception it has helped us to gain a greater understanding of ourselves and our interactions with the world. Many psychological experiments have been valid and ethical, allowing researchers to make new treatments and therapies available, and giving other insights into our motivations and actions. Sadly, others have ended up backfiring horribly — ruining lives and shaming the profession. Here are ten psychological experiments that spiraled out of control. 10. Prisoners and guards In 1971, social psychologist Philip Zimbardo set out to interrogate the ways in which people conform to social roles, using a group of male college students to take part in a two-week-long experiment in which they would live as prisoners and guards in a mock prison. 9.

The human hippocampus is not sexually-dimorphic: Meta-analysis of structural MRI volumes. Hippocampal atrophy is found in many psychiatric disorders that are more prevalent in women. Sex differences in memory and spatial skills further suggest that males and females differ in hippocampal structure and function. We conducted the first meta-analysis of male-female difference in hippocampal volume (HCV) based on published MRI studies of healthy participants of all ages, to test whether the structure is reliably sexually dimorphic. Using four search strategies, we collected 68 matched samples of males' and females' uncorrected HCVs (in 4418 total participants), and 36 samples of male and female HCVs (2183 participants) that were corrected for individual differences in total brain volume (TBV) or intracranial volume (ICV). Pooled effect sizes were calculated using a random-effects model for left, right, and bilateral uncorrected HCVs and for left and right HCVs corrected for TBV or ICV. Keywords: Brain; Gender; Morphometry; Sex difference; Systematic review.
Woman Who Hoarded Nearly 50 Dogs Was Reportedly Eaten By Pets After She Died A reported Arkansas animal hoarder was eaten by her dogs after she died inside her overcrowded home. The 65-year-old woman, whose identity has not been released, was found in August dead and partially eaten inside her Van Buren County home after having suffered from Hepatitis C, KARK-TV reported. Read: 5-Year-Old Boy is Mauled to Death By 2 Dogs Deputies discovered nearly 50 malnourished dogs-- some extremely aggressive-- on the property and were reportedly forced to shoot and kill some to get to the woman. “It was just a situation I don't want to go through again,” Van Buren County Animal Control Director Reta Tharp told the Huffington Post. A veterinarian was also bitten during the incident. The woman's death was announced this week, after authorities had returned to the property where they killed an additional 27 dogs, according to KARK-TV. About eight dogs are still on the property and will either be captured or killed. It was not immediately clear how the woman came to own the dogs.
Psychoanalysis Psychoanalysis is a set of psychological and psychotherapeutic theories and associated techniques, originally popularized by Austrian physician Sigmund Freud and stemming partly from the clinical work of Josef Breuer and others. Since then, psychoanalysis has expanded and been revised, reformed and developed in different directions. This was initially by Freud's colleagues and students, such as Alfred Adler and Carl Gustav Jung who went on to develop their own ideas independently from Freud. Later neo-Freudians included Erich Fromm, Karen Horney, Harry Stack Sullivan and Jacques Lacan. The basic tenets of psychoanalysis include the following: Under the broad umbrella of psychoanalysis there are at least 22 theoretical orientations regarding human mental development. Psychoanalysis has received criticism from a wide variety of sources. History[edit] 1890s[edit] The idea of psychoanalysis first started to receive serious attention under Sigmund Freud. 1900–1940s[edit] 1940s–present[edit]
New wonder drug matches and kills all kinds of cancer — human testing starts 2014 Stanford researchers are on track to begin human trials of a potentially potent new weapon against cancer, and would-be participants are flooding in following the Post’s initial report on the discovery. The progress comes just two months after the groundbreaking study by Dr Irv Weissman, who developed an antibody that breaks down a cancer’s defense mechanisms in the body. A protein called CD47 tells the body not to “eat” the cancer, but the antibody developed by Dr Weissman blocks CD47 and frees up immune cells called macrophages — which can then engulf the deadly cells. The new research shows the miraculous macrophages effectively act as intelligence gatherers for the body, pointing out cancerous cells to cancer-fighting “killer T” cells. The T cells then “learn” to hunt down and attack the cancer, the researchers claim. The clinical implications of the process could be profound in the war on cancer. This turns them into a personalized cancer vaccine.
