...study by a MIT professor published last week in the journal Neuron suggests that sleeping rats exhibit brain activity that may resemble human dreams. This discovery may shed light on the link in humans between dreams and memory...
...cannot look at any neuron's activity and say that the person or animal is conscious or aware of that activity," says Robert A. Stickgold, assistant professor of psychiatry at Harvard Medical School...
...protein muck that includes a substance called alpha-synuclein. No one knows exactly what alpha-synuclein does, but it's believed to play a role in the smooth transmission of nerve signals. When the substance clumps, it can't do the work it was designed to do, leading to neuron damage, loss of the neurotransmitter dopamine and eventually the familiar shakiness of such well-known Parkinson's sufferers as Janet Reno and Muhammad...
...unclear, but scientists are not waiting to find out. Other possible treatments under study include boosting antioxidants, which would protect brain cells from free radicals, highly reactive molecules that are by-products of oxidation; and blocking the body's production of compounds called excitatory amino acids, which can cause neuron damage. It's hard to say which, if any, of these treatments will succeed, but with science closing in from so many directions, it's possible that for the first time, Parkinson's disease may find itself...

Other possible treatments now under study include boosting anti-oxidants, which would protect brain cells from free radicals, highly reactive molecules that are byproducts of oxidation; and blocking the body’s production of compounds called excitatory amino acids, which can sometimes cause neuron damage. It’s hard to say which, if any, of these treatments will likely succeed, but with science closing in from so many directions, it’s possible that Parkinson’s disease-for the first time-may find itself...
