Male and female brains wired differently, scans reveal

Male and female brains wired differently, scans reveal
Scientists have drawn on nearly 1,000 brain scans to confirm what many had surely concluded long ago: that stark differences exist in the wiring of male and female brains. Maps of neural circuitry showed that on average women's brains were highly connected across the left and right hemispheres, in contrast to men's brains, where the connections were typically stronger between the front and back regions. Ragini Verma, a researcher at the University of Pennsylvania, said the greatest surprise was how much the findings supported old stereotypes, with men's brains apparently wired more for perception and co-ordinated actions, and women's for social skills and memory, making them better equipped for multitasking. "If you look at functional studies, the left of the brain is more for logical thinking, the right of the brain is for more intuitive thinking. So if there's a task that involves doing both of those things, it would seem that women are hardwired to do those better," Verma said. Related:  science and beyondGender IssueBrain & Sex

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.

Androcentrism: It’s Okay to Be a Boy, but Being a Girl… Sociologists use the term “androcentrism” to refer to a new kind of sexism, one that replaces the favoring of men over women with the favoring of masculinity over femininity. According to the rules of androcentrism, men and women alike are rewarded, but only insofar as they are masculine (e.g., they play sports, drink whiskey, and are lawyers or surgeons w00t!). Meanwhile, men are punished for doing femininity and women… well, women are required to do femininity and simultaneously punished for it. Illustrating this concept, much more concisely, is this altered photograph of James Franco in drag. Sent along by Stephanie V., the photo was originally for the cover of Candy, a “transversal style” fashion magazine. * So Caro Visi, where I found the image, credits Virus, but I can’t find it there. UPDATE: Sarah and John, in the comments thread, pointed out that the language is borrowed from a movie titled The Cement Garden. Clip from The Cement Garden:

7 Incredible Inventions by Teenage Wunderkinds When many of us were in our teens, work for science fairs comprised cut and paste displays on colorful presentation boards, and our hobbies weren't exactly about to change the world. But across the globe, teenagers with creative, scientific minds are already devising extraordinary devices, revolutionary materials and renewable technologies that might just change our planet for the greener. Click through to see some of their most incredible inventions - from bioplastics made from bananas to pee-powered energy generators and an ocean cleanup array to rid the world's oceans of waste. An Ocean Clean Up Array to Remove 7,250,000 Tons of Plastic From the World’s Oceans When we first covered Boyan Slat’s Ocean Cleanup Array it generated a phenomenal amount of excitement, as well as debate. A Way to Turn Plastic Waste into $78 Million of Biofuel 16-year-old Egyptian student Azza Abdel Hamid Faiad, meanwhile, was at work finding a way to make use of waste plastic.

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.

Penis envy Penis envy (German: Penisneid) is a stage theorized by Sigmund Freud regarding female psychosexual development, in which female adolescents experience anxiety upon realization that they do not have a penis. Freud considered this realization a defining moment in a series of transitions toward a mature female sexuality and gender identity. In Freudian theory, the penis envy stage begins the transition from an attachment to the mother to competition with the mother for the attention, recognition and affection of the father.[1] The parallel reaction of a boy's realization that women do not have a penis is castration anxiety. Freud's theories regarding psychosexual development, and in particular the phallic stage, were criticized and refined by other psychoanalysts, such as Karen Horney, Otto Fenichel, Ernest Jones, Erik Erikson, Jean Piaget, Juliet Mitchell, Clara Thompson.

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.
