Nasal spray improves memory

The 6th antiseptic in the immune system (interleukin-6) was discovered as a memory stimulant during sleep. Scientists hope to develop this substance in liquid form in nasal sprays.

Good news for students who are dealing with so many books: a nasal spray developed by German scientists promises to boost the effectiveness of the late night study if you have a good night's sleep later.

Need a good sleep to absorb what you have learned

In a research report published in the FASEB newspaper, scientists showed that a molecule from the body's immune system (the 6th antiseptic in white blood cells), when supplied through the nasal route, helps the brain. Maintain emotional and permanent memory during REM sleep (sleep dream phase).

Lisa Marshall, a member of the research team at the Department of Endocrine Neurology at Lucbeck University in Germany, said sleeping to remember as an impractical thing but capable of realism.

The first evidence that scientists have suggested is the immune signal of the sixth antiseptic plays a beneficial role in sleep-dependent long-term memory formation in humans.

To make this discovery, Marshall and his colleagues had 17 healthy young men spend two nights in the lab. In every night, after reading an emotional short story or thinking, they sprayed a liquid containing antiseptic # 6 into their noses.

Sleep and electrical activity in these brains are then monitored throughout the night. The next morning, the participants will write down the words they remember in each story. As a result, those who received a dose of antiseptic 6 could remember more words.

Gerald Weissmann, Editor-in-Chief of the FASEB newspaper, said it was an interesting discovery of science because before the 6th antiseptic was considered a product of inflammation rather than an agent. affect perception.
