When you do an activity like write, paint, or solve a crossword, it literally leads to positive electrical and molecular changes in your brain. Prioritize doing something you enjoy to make it more ...
Selenium deficiency occurs when an organism lacks the required levels of selenium, a critical nutrient in many species.Deficiency, although relatively rare in healthy well-nourished individuals, [1] can have significant negative results, [2] affecting the health of the heart and the nervous system; contributing to depression, anxiety, and dementia; and interfering with reproduction and gestation.
Maybe you’re mentally wiped after socializing all day, or your brain is fried from hours of work. If you got up early, it could simply be that you’d rather crawl under a blanket and watch ...
We have lots of work to do to really understand the sleeping human brain. Our study is only the beginning. Understanding the sleeping brain will help us tackle disorders, such as memory impairment ...
Young woman asleep over study materials. The relationship between sleep and memory has been studied since at least the early 19th century.Memory, the cognitive process of storing and retrieving past experiences, learning and recognition, [1] is a product of brain plasticity, the structural changes within synapses that create associations between stimuli.
In the same article in Scientific American, John Henley, a neurologist at the Mayo Clinic in Rochester, Minnesota, states: "Evidence would show over a day you use 100 percent of the brain". [ 1 ] Although parts of the brain have broadly understood functions, many mysteries remain about how brain cells (i.e., neurons and glia) work together to ...
Selenium is found in metal sulfide ores, where it substitutes for sulfur. Commercially, selenium is produced as a byproduct in the refining of these ores. Minerals that are pure selenide or selenate compounds are rare. The chief commercial uses for selenium today are glassmaking and pigments. Selenium is a semiconductor and is used in photocells.
"Much like muscle and that old saying 'if you don’t use it, you lose it,' using your brain can help protect it, to an extent, from some typical memory decline and slowing," says Carrie Ditzel ...
