Sorting out stroking sensations: Biologists find individual neurons in skin that react to massage
Jan. 30, 2013 The skin is a human being’s largest sensory organ, helping to distinguish between a pleasant contact, like a caress, and a negative sensation, like a pinch or a burn

Guidelines for brain amyloid imaging in Alzheimer’s
Jan. 28, 2013 Only recently has it become possible to create high-quality images of the brain plaques characteristic of Alzheimer’s disease in living people through positron emission tomography (PET). Even so, questions remain about what can be learned from these PET images and which people should have this test.

Chance finding reveals new control on blood vessels in developing brain
Jan. 24, 2013 Zhen Huang freely admits he was not interested in blood vessels four years ago when he was studying brain development in a fetal mouse. Instead, he wanted to see how changing a particular gene in brain cells called glia would affect the growth of neurons

Pavlov’s rats? Rodents trained to link rewards to visual cues
Jan. 23, 2013 In experiments on rats outfitted with tiny goggles, scientists say they have learned that the brain’s initial vision processing center not only relays visual stimuli, but also can “learn” time intervals and create specifically timed expectations of future rewards.
One form of neuron turned into another in brain
Jan. 20, 2013 A new finding by Harvard stem cell biologists turns one of the basics of neurobiology on its head — demonstrating that it is possible to turn one type of already differentiated neuron into another within the brain
