Animal research discovers brain mechanism that can't remember dreams

have you ever dreamed of an experience you can't remember? In animal trials, U.S. and Japanese researchers found that an appetite-controlling hormone in the brain may also be involved in regulating memory, making dreams easy to forget in case brain information is overloaded.
's study, published in the latest issue of the American journal Science, showed that 52.8 percent of mice that secrete the "melanin aggregation hormone", a molecule involved in regulating appetite, are activated in "fast eye movement sleep." Studies have shown that only 35 percent of the lower pasalpycleal cells are activated when the mice are awake.
Researchers used genetic tools to activate or turn off neurons in the brains of mice that secrete melanin aggregation hormones, and found that activating these neurons during fast eye-moving sleep can make mice's memory worse and, conversely, better.
, the animal's eyeballs move quickly, the body muscles relax, and dream, but wake up with most of the dreams forgotten, according to The Associated State. Co-author Thomas Kilduff, director of the Center for Neuroscience at the Stanford Institute in the United States, said the results showed that the activation of certain neurons controls whether the brain remembers information in dreams.
study found that these hypothyhea cells play a role in learning and memory function by sending inhibitory signals through long axons to the body, which is the brain's memory center. Researchers say the discovery of forgetfulness mechanisms in sleep is expected to improve understanding of memory-related diseases such as post-traumatic stress disorder and Alzheimer's disease.
