How is brain wave involved in memory formation?



The brain is constantly producing brain waves, which are electric signals, and brain waves are longNeuronIt is thought that it is a byproduct by the activity of. But,MITStudies have revealed that two parts of the brain generate different brain waves and play an important role in memory formation.

The research of MIT's neuroscientist Earl Miller is a brain organ related to learning abilityHippocampusWhenPrefrontal cortexIt generates two different brain waves and clarifies that it plays an important role in memory formation that connects irrelevant things.

In the research, we conducted experiments on the formation of manifest memories, which are conscious memories to remember. Experiments link objects such as names, faces, places, and events. They show pairs of pictures of animals and memorize them, pay the rewards if they answer correctly, and buzzer if they make a mistake. When an animal memorizes a photograph in this experiment, it detects an electroencephalogram from the hippocampus and the prefrontal cortex.

As a result of the experiment, it was found that different brain numbers were generated by the reaction in the case where the inference about the problem is correct and the case where it is wrong. When the inference is correct, the brain wave is a beta wave, and if the inference is wrong the brain wave was a theta wave.


Previous studies have shown that the beta wave strengthens the connection between neurons of memory and the theta wave weakens the association between neurons and the same thing happens in this experiment as well, in the case of the correct answer, neurons Mr. Miller is thinking that strengthening the connection between the neurons and strengthening the connection of neurons, in the case of incorrect reasoning, forgetting that they are wrong.

Miller, a neuroscientist at MIT, is researching whether it is possible to boost learning ability by generating a beta wave by electric stimulation.
