Moreover, researchers have discovered the associated brain wave pattern, which seems to be a factor that determines whether the image was later forgotten or retained. This second sample can be found in the brain hippocampus, which is important for memory retention.
This is important, researchers say, because the brain preserves some memories even when you recall that you will remember. "Forgotten pictures just disappear from the brain," says researcher Hui Zhang in a statement.
Discovery may develop a new therapy for people with memory problems.

At the same time, the second study of American researchers revealed what could be the primary brain's sleep change. The study has shown a nerve cell battery that is called a ventraltalial preopic nucleus (VLPO), which seems to be asleep.
Genetically Technological Mice, researchers at Beth Israel's Deaconess Medical Center in Boston used both chemical and optical techniques to stimulate VLPO brain cells. In both cases, mice that cause cells to fall asleep. The results confirmed that the cells of VLPO are active and are harmful to their insomnia.
"Our paper is the first test of what will happen when the VLPO neurons are activated," says Clifford Surfer, chair of the Neurology Department at Beth Israel's Diagnostic Medical Center. "Conclusions support our initial observation that VLPO cells are essential for normal sleep."
The study will promote the future development of drugs and therapy to help them with insomnia and other sleep disorders.
The last interesting note: Although researchers have been "sleeping" with cells, they discovered that these neurons have been activated by the mice body temperature dropped to six degrees. This phenomenon can be associated with deeper sleep and reduced body temperature of animals that winter in the winter.
