A group of researchers from the United States believes that a microchip that will help create memories in the damaged brain, can be implanted in the brain of a volunteer in the next two years.
Scientists from the University of Southern California, Wake Forest University, and others have investigated hippocampus — a part of the brain that plays an important role in the formation of long-term memory (about ten years).
They believe that years of research aimed at to figure out how to appear memories serve as the basis for the production of the implant, which can help people with localized brain injury, physical damage to victims and patients suffering from Alzheimer's disease.
Researchers have conducted a series of experiments on rats and monkeys have proven that the messages of the brain can be reproduced by electrical signals from the silicon chip. A group of scientists, inspired by the results of his findings, said that the devices that will be able to reproduce the processes of memory, will be available to patients in the next 5-10 years.
Professor Ted Berger, a neuroscientist and biomedical engineer at the University of Southern California, told reporters: "We do not insert some memories back to the brain. Due to implant there is an ability to generate memories. I never thought I would see something like this in my life. I can not draw from it for myself, but my children will. "
Rob Hampson, a professor of physiology and pharmacology at Wake Forest University, added: "We will continue to move forward. Every day, these implants are becoming more real. "
The researchers focused on the hippocampus, which is located deep within the brain and consolidating information from short-term memory into long-term. They hope that the future will be able to copy the implant posts neurons in the brain and play them using electrical signals of the chip.
Hampson added: "Now we support and strengthen the signal in the hippocampus, but we are moving forward with the confidence that if we are able to study this area of the brain well enough to copy its features, we can do without the hippocampus."
The researchers hope the device will help patients who have brain activity was disrupted due to a localized injury or stroke. The ultimate objective is the treatment of people suffering from Alzheimer's disease, but that would require further investigation as the disease affects multiple areas of the brain.
