Brain-to-Brain Interface Allows Transmission of Tactile and Motor Information Between Rats 1000s of Miles Apart

Researchers electronically linked the brains of pairs of rats for the first time, enabling them to communicate directly to solve simple behavioral puzzles. A further test of this work successfully linked the brains of two animals thousands of miles apart - one in Durham, N.C., and one in Natal, Brazil.

The image shows the set up and output images for this research. The caption best explains the image.

Neuroprosthesis Gives Rats the Ability to ‘Touch’ Infrared Light

Researchers have given rats the ability to "touch" infrared light by fitting them with an infrared detector wired to microscopic electrodes implanted in the part of the mammalian brain that processes tactile information. The study demonstrated that a novel sensory input could be processed by a cortical region specialized in another sense without "hijacking" the function of this brain area.

The image shows the ECoG grid location and ECoG signal modulation. The image is best described in the caption.

Researchers Describe Technology that Lets Spinal Cord Injured Man Control Robot Arm with Thoughts

Researchers describe how an electrode array sitting on top of the brain enabled a 30-year-old paralyzed man to control the movement of a character on a computer screen in three dimensions with just his thoughts. It also enabled him to move a robot arm to touch a friend’s hand for the first time in the seven years.

Brainwave Training Boosts Network for Cognitive Control and Predicts Mind Wandering

Using several neuroimaging methods, a team of researchers working at the University of Western Ontario have now uncovered that functional changes within a key brain network occur directly after a 30-minute session of noninvasive, neural-based training.

Feeling Robotic Arms Improves Brain Machine Interfaces

Proprioception feedback of a robotic arm helped improve the performance of monkeys using brain machine interfaces to control a computer cursor. When the monkeys were fit with exoskeletons that provided arm movements synchronized with the cursor movement, control of the cursor improved by 40%.
