American scientists have developed a neuroprosthesis to improve recall of certain memories. However, further research is needed for its real application.
This is reported by Science Alert with reference to a study published in the scientific journal Frontiers in Computational Neuroscience.
The study is based on a 2018 experiment that tested neural implants. With their help, scientists “recorded information codes” in the hippocampus – a place in the brain where memories are “stored”.
These “codes” were developed to simulate the neural activity that occurs during memorization of information.
Now, scientists from Wake Forest University and the University of Southern California conducted an experiment in which 14 adults with epilepsy were surgically implanted with brain electrodes. So they tried to create a map of the brain and determine the epicenters of attacks.
Next, the scientists observed the patterns that arise when memorizing specific images – animals, buildings, plants, tools, and means of transportation.
When scientists performed artificial brain stimulation according to the discovered scheme, the study participants remembered the images they saw better by about 22%.
However, the results increased to almost 38% when the researchers stimulated both brain hemispheres of participants with impaired memory.
“Our goal is to create an intervention that can restore memory function lost due to Alzheimer’s disease, stroke or traumatic brain injury. We found that the most pronounced changes occurred specifically in people with impaired memory.” – explained research co-author Brent Roeder.
The scientists say their development has potential, but further research and development is needed before it can be put into practice.
It will be recalled that scientists have established that the human brain processes traumatic memories as present experiences.
