...issue of Neuron, investigators at MIT have come up with an imaginative tool for finding out: high-speed video technology that works at 3,200 frames per second - approximately 100 times faster than home video. "There were hypotheses before," says Christopher Moore, member of the McGovern Institute for Brain Research at MIT and senior author of the study. "But now we can actually see how these whiskers work and what they are sensing...
...Scientists already knew that similar to the way a fingertip moves across a surface, the 50 or so hairs on a rat's cheek vibrate against an object to perceive its shape and texture. The video technology revealed the fluid micromotions of the whiskers, which send signals to the brain where they're interpreted as a sensory experience. What's more, the scientists were also able to study how different kinds of whiskers transmit different kinds of sensations. Short hairs, which are located on the front of the snout, transmit higher frequencies and vibrate fastest, while longer whiskers, which...
...last year, an ongoing study at the University of Florida showed cord-blood cells could also be effective at treating type-1 diabetes. Many doctors also believe that these transplants will eventually prove useful in regenerative medicine, helping patients suffering from heart disease, spinal bifida or even traumatic brain injuries...

...heart of the mental illness craze is the question of what constitutes a normal, healthy mind. As scientific knowledge expands its understanding of genomics and the chemical make-up of the brain, there is a temptation to declare what should be considered a model specimen of Homo sapiens. However, the greatest contributor to human diversity is not large-scale cultural, environmental, or genetic diversity, but rather the basic differences that makes every brain unique. To load a person up on chemicals or therapies in order to iron out the aspects of his personality that don’t correspond...
