A neuron that makes dreams hard to remain in memory Is it present in the brain?
The dream I had when I was sleeping is hard to remember, but a group of Nagoya University has revealed through experiments using mice that the neuronal system that causes these things is in the brain.
A research group of Prof. Akihiro Yamanaka from Nagoya University investigated the function of special neurons called MCH neurons, which exist only in the brain where sleep and appetite are regulated. .
As a result, it was found that a part of MCH neurons works actively when REM sleep, which is a shallow sleep, and as a result, suppresses the activity of the part that controls memory.
The research group has also confirmed that when the MCH neurons are activated artificially, memory ability declines, and this work may make it difficult for dreams during REM sleep to remain in memory. .
Professor Akihiro Yamanaka says, “There may be a system of neurons in the brain that makes it difficult for dreams to remain in memory, so dreams are not confused with reality.”
