United Kingdom study shows lack of sleep may damage the memory

United Kingdom researchers on experimental rat study shows that lack of sleep may damage the memory. Researchers said the study findings and previous lack of sleep for the new knowledge to bad memory study results are consistent.

According to New Scientist magazine reports, Princeton University, a research team in experimental rats in research for 72 hours without sleep, results show that no sleep will make the pressure laboratory rat brain hormone in the hippocampus, which impede new accumulating of the memory cell growth.

Responsible for the study of Elizabeth · Gould said that the study found that this kind of rodent main pressure hormone produced by the adrenal gland ketone, the lower the ability of nerve cell growth. And through experimental mouse adrenal resection to block this pressure hormone production, even if they do not allow mice to sleep, they still can continue as usual with a new nerve cells. So the researchers believe that lack of sleep causes stress hormone levels increase, resulting in a decrease, diminish some neurons learning ability and memory.

Researchers said the study explains shifts (day and night shift rotation) how to create images on memory, because the shift will produce "a different hormones in the environment."

However scientists think that mice lacking sleep time experienced by unusually long, equal to the number of days without sleep, so despite the lack of sleep may damage the memory, but this will only occur in extreme circumstances.
