Cortical-spinal prosthesis directs “targeted movement” in paralyzed limbs

http://www.nature.com/ncomms/2014/140218/ncomms4237/full/ncomms4237.html Cornell‘s Maryam Shanechi, Harvard‘s Ziv Williams and colleagues developed a cortical-spinal prosthesis that directs “targeted movement” in paralyzed limbs. They tested a prosthesis that connects two subjects by enabling one subject to send its recorded neural activity to control limb movements in a different subject that is temporarily sedated. The BMI is based on a set of real-time […]

Trial: Improved sense of touch and control in prosthetic hand

http://stm.sciencemag.org/content/6/222/222ra19 In the ongoing effort to improve the dexterity of prosthetics, a recent trial showed an improved sense of touch and control over a prosthetic hand.  EPFL professor Silvestro Micera and colleagues surgically attached electrodes from a robotic hand to a volunteer’s median and ulnar nerves. Those nerves carry sensations that correspond with the volunteer’s index finger and […]
