　　Scientists from the United States found that the brain is responsible for the formation of long-term memory (about 10 years) when studying and analyzing the hippocampus. They believe that they can calculate how human memory is formed, and implant chips to help local brain damage, stroke and Alzheimer’s. The patient recovers memory. Professor Ted Berger, a biomedical engineer and neuroscientist at the University of Southern California, pointed out that instead of returning someone’s memory to the brain, we replicate the memory of the brain through a chip implanter.

　　Researchers have now conducted experiments on the brains of rats and monkeys, confirming that brain information can be replicated through electrical signals from silicon chips. Scientists pointed out that this microchip implanter can be used to treat patients with epilepsy. This study made the research team very excited, they believe that a memory device may copy patients' memory storage for 5 to 10 years.

　　Researchers focus on the hippocampus, which is the deep tissue of the brain that can consolidate and integrate short-term to long-term memory content. They hope that electronic chip implants can replicate brain nerve information. The researched microchip can study a large amount of input and output memory content, thereby replacing the function of the hippocampus.

　　Recently, the US Department of Defense Advanced Research Projects Agency announced that it has developed a wireless, implantable brain "neuroprosthetic". As the name suggests, the product is implanted in the brain into electronic devices to store new memories or retrieve old memories. They are experimentally implanted in the entorhinal cortex and hippocampus of brain injured people; they are used to help soldiers and other patients with brain injuries recover their damaged memories. The name of this project is "Recovering Active Memory".

　　According to the plan, this project will first recruit patients with epilepsy and Parkinson's disease as research subjects to study the neural mechanism of brain memory in time and space. Then, researchers will develop brain-related computer models on this basis, and the final chip size is expected to be only one-tenth of the existing neural equipment.

　　Recently, scientists from the Lawrence Livermore National Laboratory are working to develop an ultra-mini microchip that can be implanted into the human brain to restore memory nerve cells, which will help those caused by disease, accident or war in the future People with brain damage restore memory.

　　The principle of the brain plant chip is to back up the data stored in the human brain. Once the human brain is damaged, the implanted device can re-enter the backed-up memory into the brain. The US Department of Defense Advanced Research Projects Agency, University of California, Los Angeles, neuroscientists and bioengineers, and Medronic are cooperating in research and development. Medtronic was researching a brain implant device for treating Parkinson's disease last year, which can treat Parkinson's disease by sending electrical signals directly to the brain.

　　No matter what kind of chip it is, it is intended to help patients with local brain injuries. We hope that this memory transplantation technology is best developed as soon as possible. In the future, once this technology is implemented on hardware, the ultimate goal is to treat Alzheimer's disease. The patient means that a disease like Alzheimer's that is incurable has a good solution.
