Research is underway to complement the lost memory by transplanting a device that can preserve human memory to the brain

ByJ E Theriot

As a research that has won a large amount of research funds from the Defense Advanced Research Projects Bureau of the US Department of Defense (commonly called DARPA), there are things that preserve human memory in electronic equipment and it can be useful for treatment of memory disorders such as Alzheimer's disease Sex is coming out.

Memory-saving devices snag US research funds: Nature News & amp; Comment

Human memory-saving devices get £ 20m research boost (Wired UK)

On July 9, 2014, two research teams, which study how memories are formed and retrieved in the brain and develop devices to promote these processes in the brain, are being developed from DARPA 3750 I gained research funds of as much as $ 10,000 (about 3.8 billion yen). Two research teams newly invested this time,EpilepsyHold on.Brain ImplantWe use this implant to monitor the brain's activity, investigate the electrical pattern of the brain as the brain stores and retrieve memory, and analyze the brain trauma and the brain caused by the disease It complements memory impairment by transplanting electronic equipment to the brain.

One of the research teams will work as a psychologist at the University of PennsylvaniaMichael KahanaMr. Mr. is trying to elucidate the mechanism concerning the memory of the brain by mapping the electric pattern generated in the brain by "ignition of nerve cell" when forming memory. A research team led by Mr. Michael asked about 100 epileptic patients to perform a memory game, monitored the activities of the brains of the subjects, compare the electric patterns of the best score and the worst score of each subject and compare " A stimulation pattern that can maintain the brain's performance at an optimum level ". Michael, leader of the study, says, "We will monitor brain activity and stimulate the brain using brain implants embedded in the head of epilepsy patients who are subjects."

Another research team receiving funding from DARPA serves as a neurosurgeon at the University of California Los AngelesItzhak FriedTeam headed by Mr. Mr. Itzhak's team is conducting research to create devices capable of "preserving memory", "analysis of brain activity", "stimulation to the brain in real time", and so on. The size of the device developed by Mr. Itzhak's research team is "according to the comments of the person involved in the research," The size of the device developed by Mr. Itzhak's research team is "one tenth the size of the stopwatch size device used for Parkinson's disease and depression treatment I guess it will be ". In 2012, Mr. Itzhak's research team has discovered that stimulating certain brain circuits can improve the performance of computer games, and since that time he has been studying the brains of epileptic patients until 2014. However, with the acquisition of new research funding, I comment that from now on epileptic patients will be researching patients with trauma to the brain.

Currently, the risks of experiments involving these brain implants remain unclear, but Mr. Itzhak says, "No side effects are allowed." However, British Nature magazine points out that skillful execution of brain activity patterns may hypothetically hijack the brain and interfere with other brain activities. In order to minimize these risks, Mr. Itzhak seems to be thinking "It is necessary to identify the best place to transplant brain implants," Mr. Itzhak says, "Michael said" Since the stimulus given is a trace amount, there is no effect on the brain in any way. "

The results of these studies will help patients with memory disorders such as Alzheimer's disease, which is a disease of cerebral trauma and nerve tissue degeneration, to remember things newly and to search memory in the brain It may seem that it will not lead to regain the lost memory.
