What gives us fingertip dexterity?

USC Viterbi School of Engineering biomedical engineer Francisco Valero-Cuevas is working to understand the biological, neurological and mechanical features of the human hand, features that enable dexterous manipulation and make it possible for a person to grasp and crack an egg, fasten a button or fumble with a cell phone to answer a call.

   Quickly moving your fingertips to tap or press a surface is essential for everyday life to, say, pick up small objects, use a BlackBerry or an iPhone. But researchers at the University of Southern California say that this seemingly trivial action is the result of a complex neuro-motor-mechanical process orchestrated with precision timing by the brain, nervous system and muscles of the hand.

4. Miniature robot for precise positioning and targeting in neurosurgery wins award for HU researcher
   06-05-2007 · EurekAlert!
   While recent advances in neurosurgery have made it possible to precisely target areas in the brain with minimum invasiveness -- using a small hole to insert a probe, needle or catheter -- there remains a disadvantage. The small size of the openings reduces or eliminates direct site visibility and requires greater dexterity, stability and precision by the surgeon.
