Can traumatic memories be erased? Cell biology offers promise
(Medical Xpress) -- Could veterans of war, rape victims and other people who have seen horrific crimes someday have the traumatic memories that haunt them weakened in their brains? In a new study, UCLA...
View ArticleNew study identifies compounds that could slow down Alzheimer's disease
A family of naturally occurring plant compounds could help prevent or delay memory loss associated with Alzheimer's disease, according to a new study by the Translational Genomics Research Institute...
View ArticleScientists discover drug candidate for Alzheimer's, Huntington's disease
Scientists at the Gladstone Institutes have identified a drug candidate that diminishes the effects of both Alzheimer's disease and Huntington's disease in animal models, offering new hope for patients...
View ArticleConnecting neurons to fix the brain
Each of the brain's 100 billion neurons forms thousands of connections with other neurons. These connections, known as synapses, allow cells to rapidly share information, coordinate their activities,...
View ArticleStudy provides potential explanation for mechanisms of associative memory
Researchers from the University of Bristol have discovered that a chemical compound in the brain can weaken the synaptic connections between neurons in a region of the brain important for the formation...
View ArticleDodging the cognitive hit of early-life seizures
About half of newborns who have seizures go on to have long-term intellectual and memory deficits and cognitive disorders such as autism, but why this occurs has been unknown. In the December 14...
View ArticleAlzheimer's drug candidate may be first to prevent disease progression
A new drug candidate may be the first capable of halting the devastating mental decline of Alzheimer's disease, based on the findings of a study published today in PLoS One.
View ArticleNew target for Alzheimer's drugs
(Medical Xpress) -- Biomedical scientists at the University of California, Riverside have identified a new link between a protein called beta-arrestin and short-term memory that could open new doors...
View ArticleCocaine and the teen brain: Study offers insights into addiction
When first exposed to cocaine, the adolescent brain launches a strong defensive reaction designed to minimize the drug's effects, Yale and other scientists have found. Now two new studies by a Yale...
View ArticleHandful of genetic changes led to huge changes to human brain
Changes to just three genetic letters among billions led to evolution and development of the mammalian motor sensory network, and laid the groundwork for the defining characteristics of the human...
View ArticleBlue Brain Project accurately predicts connections between neurons
One of the greatest challenges in neuroscience is to identify the map of synaptic connections between neurons. Called the "connectome," it is the holy grail that will explain how information flows in...
View ArticleScientists explain how ketamine vanquishes depression within hours
(Medical Xpress)—Many chronically depressed and treatment-resistant patients experience immediate relief from symptoms after taking small amounts of the drug ketamine. For a decade, scientists have...
View ArticleResearchers find fly receptor neurons able to communicate without synapse...
(Medical Xpress)—Researchers at Yale University have found that neural receptors in a fly's antenna are able to communicate with one another despite a lack of synaptic connections. They suggest in...
View ArticleResearchers provide definitive proof for receptor's role in synapse development
Jackson Laboratory researchers led by Associate Professor Zhong-wei Zhang, Ph.D., have provided direct evidence that a specific neurotransmitter receptor is vital to the process of pruning synapses in...
View ArticleFlip of a single molecular switch makes an old brain young
The flip of a single molecular switch helps create the mature neuronal connections that allow the brain to bridge the gap between adolescent impressionability and adult stability. Now Yale School of...
View ArticleScientists map process by which brain cells form long-term memories
Scientists at the Gladstone Institutes have deciphered how a protein called Arc regulates the activity of neurons—providing much-needed clues into the brain's ability to form long-lasting memories....
View ArticleNew drug reverses loss of brain connections in Alzheimer's disease
The first experimental drug to boost brain synapses lost in Alzheimer's disease has been developed by researchers at Sanford-Burnham Medical Research Institute. The drug, called NitroMemantine,...
View ArticleScientists create way to see structures that store memories in living brain
Oscar Wilde called memory "the diary that we all carry about with us." Now a team of scientists has developed a way to see where and how that diary is written.
View ArticleBrain chemistry changes in children with autism offer clues to earlier...
(Medical Xpress)—Between ages three and 10, children with autism spectrum disorder exhibit distinct brain chemical changes that differ from children with developmental delays and those with typical...
