These days we are overwhelmed with information. Work, relations, new knowledge, the Internet, day after day our memory archive is packed with all of this. With such information flow it is extremely difficult at times to remember anything. Memory loss is another issue that scientists have been trying to solve for decades. A scientific breakthrough is here! In the brain of each person there is an area responsible for memories. It is called the hippocampus.
Researchers all over the globe have been working on its activation for
years. The scientists from the University of Southern California have succeeded in it. The scientists created a hippocampal neural prosthetic device and tested it in 15 subjects with various memory disorders. The
chip was implanted into the hippocampus to convert short-term memory into long-term memory by means of electrical pulses. These pulses are similar to natural operation of neural networks.
The experiment involved several stages. At first, some images were shown to the subjects and after some time they were to “recognize” these images among other pictures. At this stage the scientists identified active areas of the brain at the moment of memorizing.
After that an attention test with more complex images was given. During this test the chip stimulated the hippocampus with “proper signals” identified before. The results proved efficiency of the implanted “memory stimulator”. Compared to the first values, the short and long-term memory improved by 35% and 37% respectively. The developed device recorded and reproduced the code forming the human memory.
The scientists are hopeful that their invention will help patients with various memory disorders, for example with Alzheimer’s disease.
Certainly, the need for more extensive experiments is great. It is necessary to note the incredible activity on implementation of similar ideas in laboratories all over the world. And it speaks to the fact that
improvement of memory and thinking abilities will soon become a full-featured service for everyone.
The main thing is to remember that to live up to the scientific and technical revolution it is necessary to take
care of our brain today. Develop your intellectual potential; augment capacities of your memory, attention, intelligence, and information processing speed. As your active longevity and real-life capacities directly depend on proper brain functioning.
