A development is done by U.S researcher which will help encode the memories of disabled brain. This research gives hope to persons who are suffering from Alzheimer’s as well as soldiers who are not able to remember the recent past because of their injuries.
The collaboration of Southern California University and Medical Centre named Wake Forest Bapist have come up with a small array of electrodes which can be implanted into the brain.
What is the key research about?
Basically, the key research is all about a computer algorithm which mimics the electrical signals that are used by brain to translate the short term memories into permanent memories. This algorithm helps in bypassing the damaged or diseased area even though there is not a single way of reading the memory.
According to Project Leader, Ted Berger of USC, the algorithm is all about translating like translating from Spanish to French without being able to understand the either of the languages.
Test Done by Researchers
Before implementing the formula on Human Beings, initially the test were done on rats and monkey. In Milan the conference of IEEE was held and in that conference one of the team members informed regarding evaluating the test on human brains.
How will this research help?
According to researchers, this formula will be helpful to treat the patients suffering from neurodegenerative disease which includes Alzheimer’s by enabling the signals to bypass the damaged circuitry in the hippocampus which is brain memory center.
Brain already have sensory inputs like sight, sound, smell or feelings. Creating a complex electrical signals which are known as spike trains which travels through hippocampus. The neutral process includes re-encoding the signals several times so that they can have quite different electrical signature by the time they are ready for long term storage.
How this algorithm works?
Due to damage in brain the translation of the memories prevents that is why they are not able to recall the things that have happened in past. Now, with the help of this algorithm there is an electrical input and output of the signals which is created in patient’s brains. This helps in conducting the task such as remembering the position of different shapes on a computer screen. The results were redefined where the algorithm provides 90 percent accuracy of translating the signals.
Researchers are now planning to implement the devices for paralyzed patients to carry out the simple movements with the help of robotic arms or even on their own limbs. But no one else is using the computers to manipulate the memory signals directly into human brain.
