A middle-aged woman, paralyzed except for the ability to tilt her head and move her eyes, sits in a wheelchair. Extending from the top of her head is a plug, with a cord running from it to a computer linked to a monitor. On the monitor screen is a display of a standard QWERTY keyboard. Silently a cursor moves across the keyboard. Asked how she likes using this system, she deliberately picks out the letters E-X-C-I-T-I-N-G. Amazingly, she does this just by thinking of her hand controlling and clicking an imaginary mouse.

Recent NIDCD and NIH Research News

Scientists have noticed for decades that rodents take their dining clues from their peers, basing their preferences for different foods on the last thing one of their buddies ate. It’s a behavioral strategy that could be seen as a way to stack the deck against eating harmful or poisonous foods. But no one had been able to explain how the brain put the two odors together to signal “okay to eat.” NIDCD-funded researcher Richard Munger, Ph.D., at the University of Maryland School of Medicine, along with an international team of researchers, used knock-out mice to show that the behavior is the result of a dedicated subsystem of specialized olfactory receptors in the nose and neural circuits in the brain.

Wind turbines, giant propellered contraptions that turn wind power into electricity, are rapidly becoming popular as green energy sources in Europe and the United States. This is good for the environment, but the rotors and blades of wind turbines generate noise in the infrasound range that some people claim makes them feel dizzy or unable to sleep, among other symptoms.

Thanks to research funded by the NIDCD and conducted by Stefan Heller, Ph.D., and a group of colleagues at Stanford University School of Medicine, scientists have a way to grow abundant numbers of functional inner ear hair cells using embryonic mouse stem cells and a combination of growth-inducing substances.
