Neural prosthesis restores normal behavior after brain injury

A new study published in PNAS this month reported used of Brain Machine Interface to successfully restore behavior, in this case, the ability to reach through a narrow opening and grasp food, in a brain-injured rat. Ultimately, the team hopes to develop a device that rapidly and substantially improves function after brain injury in humans.

3D printer creates realistic neurosurgical models for training

A new multi-material 3D printer was used to create realistic, low-cost model of the skull for use by students in practicing neurosurgical techniques. The model uses a variety of materials that simulate the various consistencies and densities of human tissues encountered during neurosurgery.

Neurosurgery is a difficult discipline to master. Trainees may spend as many as 10 years after graduation from medical school developing and honing their surgical skills before they can be designated as proficient in their specialty. The greater the number and variety of neurosurgical training sessions, the better the training experience.

However, the researchers say, it’s difficult to find suitable simulation models that offer accuracy and realism for neurosurgical training while keeping training costs down.

Three-dimensional printers have been used to create models of normal and pathological human tissues and organs for physician training and patient instruction for some time.  Until recently, however, only one material could be used in the creation of models, which is of little value for hands-on training.

Mind-controlled robots in manufacturing, medicine

University at Buffalo researchers are developing brain-computer interface (BCI) devices to mentally control robots. “The technology has practical applications that we’re only beginning to explore,” said Thenkurussi “Kesh” Kesavadas, PhD, UB professor of mechanical and aerospace engineering and director of UB’s Virtual Reality Laboratory. “For example, it could help paraplegic patients to control assistive devices, or it could help factory workers perform advanced manufacturing tasks.”
