'red hair' gene variant may underlie association between melanoma and parkinson'




a gene variant that produces red hair and fair skin in humans and in mice, which increases the risk of the dangerous skin cancer melanoma, may also contribute to the known association between melanoma and parkinson's disease. in their paper appearing in the march issue of annals of neurology and pre...



plastic synapses offer hardware alternative to neural networks




enlargemooganicshare this storyneural networks were all the rage for a while, but progress eventually slowed and interest cooled. then, as computing power increased, the field experienced a renaissance, and deep learning was the new big thing.throughout this ebb and flow of interest, there has been ...



'jumping genes' may set the stage for brain cell death in alzheimer's, other dis

brain cells show teamwork in short-term memory: western university study




nerve cells in our brains work together in harmony to store and retrieve short-term memory, and are not solo artists as previously thought, western-led brain research has determined.the research turns on its head decades of studies assuming that single neurons independently encode information in our...



neurons recall place-related memories if you just get close




enlarge/ fear is the mind killer.lalumiere lab, university of iowashare this storyplace cells in the hippocampus are known to encode memories associated with a specific location. however, the precise role that these cells play in location-based memory retrieval is somewhat unclear. a recent study u...



precise technique tracks dopamine in the brain




cambridge, ma -- mit researchers have devised a way to measure dopamine in the brain much more precisely than previously possible, which should allow scientists to gain insight into dopamine's roles in learning, memory, and emotion.dopamine is one of the many neurotransmitters that neurons in the br...



learning can be much easier if you follow this 5-step approach




learning a new concept can be a rewarding experience, yet it is frustrating when new information simply floats around in your head without sticking. often times, we are forced to read a book repeatedly just to get the information to store in our memory.learning should not be simply about forced memo...

researchers identify how inflammation spreads through the brain after injury




researchers have identified a new mechanism by which inflammation can spread throughout the brain after injury. this mechanism may explain the widespread and long-lasting inflammation that occurs after traumatic brain injury, and may play a role in other neurodegenerative diseases.the findings were ...



saving brain cells from stroke




researchers from the university of iowa carver college of medicine and the university of miami miller school of medicine have shown that a neuroprotective compound tested in rats provides two-pronged protection for brain cells during stroke and improves physical and cognitive outcomes in the treated...



a backup copy in the central brain: how fruit flies form orientation memory




insects have a spatial orientation memory that helps them remember the location of their destination if they are briefly deflected from their route. researchers at johannes gutenberg university mainz (jgu) have examined how this working memory functions on the biochemical level in the case of drosop...



novel syndrome highlights the importance of rare disease research




a group of researchers from pakistan, europe and singapore have identified and characterised a previously undiscovered rare deafness-dystonia syndrome in a family living in a remote region of pakistan. the research, published in disease models & mechanisms, describes how five of the eight children i...



alcoholism may be caused by dynamical dopamine imbalance




researchers from the higher school of economics, ecole normale supérieure, paris, indiana university and the russian academy of sciences nizhny novgorod institute of applied physics have identified potential alcoholism mechanisms, associated with altered dopaminergic neuron response to complex dyna...
