DARPA
Last year, researchers successfully managed to design and implement a brainimplant that acted as a bypass for damaged brain tissue. This neural prosthesissuccessfully restored brain function in rats, demonstrating that the closed-loopbrain-machine-brain interface could one day perform the same function in brain-damaged humans.
And it may occur soon, with DARPA taking up the reins to fund research on just sucha device. Called the Restoring Active Memory (RAM) program, conducted by theUniversity of California and the University of Pennsylvania, it is being developed in

the hope of restoring memory function in veterans who have suffered a traumaticbrain injury.
Currently, over 270,000 military service memberssince 2000 and an estimated 1.7 million civilians inthe US are affected by TBI, which often manifestsas an inability to retrieve memories formed beforebeing injured and an impaired ability to form newmemories. There are also no effective treatmentsavailable.
The teams will first develop computer models thatdescribe how neurons code memories, as well asanalysing neural signals in order to understandhow targeted stimulation might help restore thebrain's ability to form memories.
The UCLA team will use data collected from epilepsy patients that already haveelectrodes implanted in their brains to develop a model of the hippocampal-entorhinal system -- known to be involved in learning and memory.
The Penn team will study neurosurgical patients with implanted brain electrodes,recording data as they play computer-based memory games in order to gain anunderstanding of how successful memory function works. All patients will bevolunteers.
The teams then plan to integrate these models into implantable closed-loopsystems.
Like the research on rats, the implant will pick up neural signals from anundamaged section of the brain and route it around the damaged portion,effectively forming a new neural link that functions as well as the undamaged brain.

Is it likely that it will be implemented for civilian use later down the road? I was in arollover when I was 16, and now suffer from TBI among other things.

Soon technology like this could one day to prove cases beyond a reasonable doubtabout a persons innocence.
Image the ability to have a blue tooth device for those brain parts that will let you know ifthe person is full of BS or they are telling the truth with the added benefit of knowingthey have not suffered from any affect that may impair judgement.
