ZONAUTARA.com – Generating memories or creating false memories it feels like we can only see it in science fiction movies. However, scientists are now developing a machine that can create false memories, it is a holographic brain modulator (holographic brain modulator).
Researchers at UC Berkley have developed it, details of which are published in the journal Nature Communications under the title Three-dimensional scanless holographic optogenetics with temporal focusing (3D-SHOT).
Despite the possibility of abuse, this finding has many benefits. Like helping patients get back memory lost, or even lost senses.
Modulator brain monitor and modify neural activity. It does this by isolating specific sets of neurons, first tens, then hundreds, and then thousands at a time, and stimulating them in specific patterns that mimic real brain activity. As a result, it is able to trick the brain into believing that it has felt, seen, or experienced an event or phenomenon that never happened.
Alan Mardinly, co-author of the study who is a doctoral student at UC Berkeley, said the findings are one of the first steps in a long journey to develop technology that could be implanted. brain virtual with additional or enhanced senses.
So far, the research has been tested on laboratory mice. With their heads unable to move, they were forced to walk on a treadmill. UC Berkeley scientists then used this technique to target specific neurons, stimulating the surface of a part of the brain called the somatosensory cortex, which is the brain’s motor center.
The scientists placed a holographic barrier in the rat’s path as they walked. This happens in their brains, like an illusion. Although the scientists didn’t see any behavioral changes, monitoring showed that the mice’s brains responded as if the barriers were real.
Computer-generated holography is used to simulate obstacles. Holography works by focusing attention on a 3D area brain, which is made up of thousands of different neurons. The modulator activates 50 of them at once using 3D laser techniques. First one stack of 50 is activated, then another and more up to 300 times per second.
With these findings, scientists believe that there will come a time when they will have the ability to control neural activity in the cortex, and thus be able to recreate any perception or sensation a person can think of.
