Not only beauty, wearing headband also helps us to be smarter

The idea of ​​a headband that can help you become smarter sounds like a science fiction device in blockbuster movies. However, this is about to come true.

According to the researchers, the device could increase learning efficiency by 40%. You won't have to wait too long to own this marvelous ribbon , because it is expected that the device will be widely used within the next 5 to 10 years.

The device is part of the Restoring Active Memory Project (RAM, roughly translated), developed by the Department of Defense DARPA's Advanced Defense Projects. The project involved a group of scientists from HRL labs in California, Soterix Medical Research Institute in New York, and McGill University in Montreal, Canada.

The researchers used stimulation techniques from transcranial CSCS . Accordingly, using electricity stimulates the prefrontal cortex, causing a change in the connection between different brain regions and increasing learning efficiency. Although previous experiments predicted that this result might be due to an increase in neuron activity, scientists have discovered that this is not the main reason. Instead, it is the change in connectivity between brain regions that increases learning efficiency.

Dr. Praveen Pilly, lead researcher, said: "In this experiment, we focused on the prefrontal cortex by editing local limiting stimuli here. The prefrontal region. The forehead is the area that controls specialized functions such as decision making, cognitive control and contextual memory.

It is connected to most other cortical regions, so when stimulated, the effect of spread is widespread. This prefrontal cortex is also the target target of many behavioral science studies with transcranial magnetic stimulation studies'.

The researchers tested this device on long-tailed monkeys. After stimulation, they let the monkeys in the experiment perform a number of tasks related to learning from visual image data and connecting to the reward receiving location.

If not using the TDCS method, the monkeys will lose an average of 22 times to complete the task. But when using the TDCS method, the monkeys only took about 12 times (a 40% increase in learning efficiency).

Dr. Pilly said, "Behavioral effects are shown when monkeys can find rewards faster."

In fact, the ability to enhance brain function immediately is always what people dream of. Previously, this only existed in sci-fi films or novels, but with the advancement of current technology, it seems to be closer to reality.

This is not the first time a research has been conducted to create tools that can improve intelligence. In the past, a team of Boston University scientists also developed devices that improve their non-invasive learning ability. Even so, DARPA claims that their device will be cheaper and more convenient than previous technologies.
