A new study suggests that Autism starts in the womb, researchers have found a remarkable 67 per cent increase in the total number of brain cells in the prefrontal cortex of new born babies with ASD.
Children with autism appear to have too many cells in a key area of the brain needed for communication and emotional development, say US researchers. Their findings help explain why young children with autism often develop brains that are larger or heavier than normal. Dr Eric Courchesne says the finding of excess brain cells in the prefrontal cortex explains brain overgrowth in autism, and hints at why brain function in this area is disrupted. Courchesne, of the University of California San Diego Autism Center of Excellence, and colleagues, have also found dozens of genes that may raise the risk of autism. But genetic causes only explain 10 per cent to 20 per cent of cases, and recent studies have pointed to environmental factors, possibly in the womb, as a potential trigger. The team found excess brain cells in each child with autism they studied, says Courchesne. And the brains of the autistic children also weighed more than those of typically developing children of the same age.
Researchers searching for an early indicator of autism say they’ve discovered a promising possibility, an impairment in the ability of the brain’s right and left hemispheres to communicate with each other. The researchers did brain imaging scans – fMRIs – on 29 sleeping toddlers with autism, 30 typically developing kids and 13 children with significant language delays, but not autism. All were between 1 and 4 years old. The scans showed that the language areas of the left and right hemispheres of the autistic toddlers’ brains were less “in sync” than the hemispheres of the typical kids and the children with other language delays. The weaker the synchronization, the more severe the autistic child’s communication difficulties :: Read the full article »»»»

I’m NOT a baller, can’t take blubbering, dislike what it does to my eyes – eew puffiness – and definitely avoid – at all cost – falling into that wallowing sob of emotional over-out-pouring. I do however have a buddy who cries at most anything. Sat in front of the television, she’ll burst into leakiness over insurance advertisements, heaven forbid your sat next to her at the cinema. In a new study by scientists at the Weizmann Institute of Science scientists have revealed some nail biting new results. Turns out tears are an absolute cold shower to mens sexual arrousal – that explains Leksy’s disastrous relationship history – Girl Tears it turns out are chemosignal’s that turn OFF a mans major sexual hormone, testosterone, tears it’s seems Smell – and I thought it was her halitosis!?
It seems Darwin was also a denier of the emotion tearing up, in his The Expression of Emotions in Man and Animals, Charles Darwin listed three reasons for the secretion of tears: 1. “The primary function of the secretion of tears, with some mucus, is to lubricate the surface of the eye” 2. “to keep the nostrils damp, so that the inhaled air may be moist, and likewise to favour the power of smelling” 3. “But another, and at least equally important function of tears is to wash out particles of dust or other minute objects which may get into the eyes” (Darwin, 1872: 169). In Darwin’s view, the excretion of emotional tears was related to the first function and had little to do with emotion – sigh – if I could love a man! Read the full article »»»»
