Love it, indeed
Really good solution
Same as old one
The old one was better
This is a new option

People say we're running out of energy. That's only true if we stick with these old 19th century technologies. We are awash in energy from sunlight.

Brain signals from a primate directly move paralyzed limbs in another primate 'avatar’

RATE THIS! +27

Taking brain-machine interfaces (BMI) to the next level, new research may help paralyzed people move their own limb just by thinking about it. Previous research has been limited to controlling external devices, such as robots or synthetic avatar arms.

 

The research team developed and tested a prosthesis that connects two subjects (monkeys) by enabling one subject to send its recorded neural activity to control limb movements in a different subject that is temporarily sedated.

 

The demonstration is a step forward in making brain-machine interfaces for paralyzed humans to control their own limbs using their brain activity alone.

 
The concept: when paralyzed patients imagine or plan a movement, neurons in the brain’s motor cortical areas still activate, even though the communication link between the brain and muscles is broken.
 
By implanting sensors in these brain areas, neural activity could be recorded and translated to the patient’s desired movement using a mathematical transform called the decoder. These interfaces could allow patients to generate movements directly with their thoughts.

Mind controlled devices are being considered more and more. This application to help paralysed patients is particularly worth while Reply

Potentials are great! Such brain-machine interface architectures could enable patients to generate complex movements using robotic arms or paralyzed limbs- this is the outcome that they would like to achieve

Mind is so complicated and just using fragments that we can manipulate could be irresponsible for the time being - this could be very exciting in the future when we know more Reply

Just recently we found out about Mind Controlled Music Player. For this, researchers recorded the various brain patterns, assigned each frequency an action and coded the software to take certain actions when particular patterns were detected- sounds easy in this case

Yes, reportedly, Samsung is preliminarily investigating mind-controlled smartphones as the next step beyond touch, gesture, and eye-controlled interfaces. Reply

Mucho cuidado. No es que nos hayan engañado, lo que pasa es que ellos no se imaginaban que los bárbaros de los sotlsiiacas hubiesen dejado un panorama a nivel económico tan negro. Reply
