Why did I come here? Brain SP can improve blurred memory


Blurred memories can be disappointing, whether you are at a grocery store or trying to remember whether you have spent the last bit of milk or in court to give testimony.

A new study now shows that turning off the brain can strengthen that memory. After stimulation in certain parts of the brain, study participants were able to remember memory better by 15.4%, a group of researchers reported in the Journal of Cognitive Neuroscience on May 6.

In particular, these subjects can better remember episodic memories that include a specific time and place. “Episodic memory has contextual details,” said senior author Jessie Risman, assistant professor of psychology and psychiatry and biochemistry at the University of California, Los Angeles.

Risman and his team gathered 72 people on two consecutive test days. On the first day, participants were shown 80 different words and asked them to remember them in context. For example, if one word is “cake”, participants are asked to imagine that they or someone else interacts with the cake. (Remembering the word “cake” is not episodic memory, but I remember eating cookies on the balcony yesterday.)

The next day, participants conducted tests to measure memory, thinking, and perception. In this estimate, they were asked to remember whether they had seen certain words the day before, and to sort them into categories, among other things.

During this time, they were connected to two electrodes and a 9 volt battery that trapped their brains in less than a minute. The rest of the time there is no closing. Mood, called fake stimulation, must tell participants that they have been cut off at any time and are only used to stimulation. (Although most respondents said more or less after the survey when they received the note)

The participants were then divided into three groups: the first group received additional brain prisons to increase the activity of specific parts of the prefrontal cortex, which is known to be important for episodic memory; The second group receives “reverse” currents (produced by reversing the polarity of the electrode), suggesting previous research or reducing brain cell activity or not producing anything at all. The third group continued to receive fake incentives.

Although participants did not see an increase in their reflection or perception after receiving the question, those who received the actual flow had a score of 15.4% higher than their pre-thrust memory test. The researchers found no significant improvement in the reflux group or inaccurate incentives.

The research limitation, however, is that researchers are not convinced that, even though they target a specific region of the brain, impulses have no effect on other regions.

According to Rissman, this is the first time a study has looked at what happens when electrical stimulation is applied when someone tries to remember memories. If not, it is not new to close the brain to improve memory.

For example, last year, a study funded by Defense Advanced Defense Research Agency (DARPA) found that closing the sleeping brain can stimulate another type of memory called “memory generalization.”

But brain fractures, including new ones, are at a very early stage. “This is a strict scenario that must exist in real life,” and that would not be very practical if people did not hang around with this camera in their heads, Rhysman said.

“Although the initial results are very encouraging, we want to do more experiments to find out how consistent these advantages are,” he said. However, researchers also want to “better handle the types of memories that are most vulnerable to this type of brainwashing.”
