This is how the first prosthesis works that improves brain memory by 50%

Little by little, researchers are taking giant steps toward a world in which brain prostheses are commonplace, allowing humans to delay brain aging and retain all of their memory capabilities.

Cognitive decline is a slow process that, it seems, is not inevitable. Just like our muscles, the brain little by little he loses his abilities that we once had as young people and a deterioration of our memory.

Though there is no cure for dementiaSome lifestyle changes have been shown to help prevent cognitive decline and even slow the rate of dementia progression. Yesterday precisely we left you 3 great tricks to avoid that rapid deterioration that causes us to lose memory.

If we add to this numerous diseases such as Alzheimer’s, which accentuate this aspect, a research process that finds solutions is more than necessary. That is why now, a group of DARPA researchers have managed to create a prosthesis to improve memory with an improvement rate of about 50% (at most).

The system is not very advanced at the moment, since it is based on a single electrode that must be placed deep in the brain. However, the prosthesis to improve memory has proven to be incredibly effective and opens the door to a whole world of possibilities and recovery of memory or memory.

How this prosthetic developed by DARPA for memory loss works

Researchers have developed two versions of his memory prosthesis: a “decoding memory model” (MDM) and a “multiple input, multiple output” (MIMO) model.

The MDM model is limited to observe electrical activity in the hippocampus when a person correctly forms a memory and then it builds a pattern and the MIMO model is trained to analyze the electrical activity in the part of the hippocampus that receives the new information and then it predicts the best pattern of electrical impulses in a different part for successful memory formation.

With all this on the table, the researchers wanted to put their prosthesis to the test (along with their two models) in 24 people who already had electrodes implanted in their brains to help doctors study your epilepsy.

The brain-computer interface reaches humans, Matrix closer and closer

Some of these individuals also had brain injuries and saw the results change depending on the electrode used. Each person completed between 100 and 150 tasks so that researchers could customize their MDM and MIMO models.

Days later, the same test was carried out again with the updated models. in the prostheses and checked if they were really effective. “We see improvements ranging from 11% to 54%”say the researchers.

Although we talk about great improvements that can solve the lives of many people, we are still a long way from a practical device that can help them if they suffer from dementia or brain injuries to recover lost memory function. It’s time to wait but, dOf course, we are on the right track.
