View ArticleZinc regulates communication between brain cells
Zinc has been found to play a critical role in regulating communication between cells in the brain, possibly governing the formation of memories and controlling the occurrence of epileptic seizures.
View ArticleMemory formation triggered by stem cell development
Researchers at the RIKEN-MIT Center for Neural Circuit Genetics have discovered an answer to the long-standing mystery of how brain cells can both remember new memories while also maintaining older ones.
View ArticleAlcoholism and HIV infection have different effects on visuomotor procedural...
The different effects on memory processes by chronic alcoholism and HIV infection likely reflect the specific neuropathology associated with each condition: frontocerebellar dysfunction in alcoholism...
View ArticleUnconscious emotional memory remains intact during alcohol intoxication, may...
(Medical Xpress) -- Although certain memory processes are impaired during alcohol intoxication, the brain does appear to retain emotionally charged images, particularly in unconscious memory processes,...
View ArticleLearning requires rhythmical activity of neurons
The hippocampus represents an important brain structure for learning. Scientists at the Max Planck Institute of Psychiatry in Munich discovered how it filters electrical neuronal signals through an...

View ArticleCholine intake improves memory and attention-holding capacity
An experimental study in rats has shown that consuming choline, a vitamin B group nutrient found in foodstuffs like eggs and chicken or beef liver, soy and wheat germ, helps improve long-term memory...
View ArticleLong-term memory in the cortex
(Medical Xpress)—'Where' and 'how' memories are encoded in a nervous system is one of the most challenging questions in biological research. The formation and recall of associative memories is...
View ArticleFeeding fruit flies with spermidin suppresses age-dependent memory impairment
(Medical Xpress)—Age-induced memory impairment can be suppressed by administration of the natural substance spermidin. This was found in a recent study conducted by Prof. Dr. Stephan Sigrist from Freie...
View ArticleBreakthrough discerns normal memory loss from disease
(Medical Xpress)—Cornell researchers have developed a reliable method to distinguish memory declines associated with healthy aging from the more-serious memory disorders years before obvious symptoms...
View ArticleSeveral forms of vitamin E protect against memory disorders
Elderly people with high serum vitamin E levels are less likely to suffer from memory disorders than their peers with lower levels, according to a study published recently in Experimental Gerontology....
View ArticleScientists identify brain's 'molecular memory switch'
Scientists have identified a key molecule responsible for triggering the chemical processes in our brain linked to our formation of memories. The findings, published in the journal Frontiers in Neural...
View ArticleScientists reverse memory loss in animal brain cells
Neuroscientists at The University of Texas Health Science Center at Houston (UTHealth) have taken a major step in their efforts to help people with memory loss tied to brain disorders such as...
View ArticleTransgenic mice ready to fight obesity—and more
Scientists at the Nencki Institute of Experimental Biology of the Polish Academy of Sciences in Warsaw investigate mice with a very precisely modified genome. Because it is possible to turn off the...
