Experience affects new neuron survival in adult brain; study sheds light on learning, memory
Experience in the early development of new neurons in specific brain regions affects their survival and activity in the adult brain, new research shows. How these new neurons store information about these experiences may explain how they can affect learning and memory in adults. view more (2007-03-23)
Neuroscientists identify how trauma triggers long-lasting memories in the brain
A research team led by UC Irvine neuroscientists has identified how the brain processes and stores emotional experiences as long-term memories. view more (2005-07-27)
Alzheimer`s Disease: Activity Generates New Nerve Cells For Old Mice
Activity Generates New Nerve Cells For Old Mice - Study Supports Link Between Active Life And Lower Risk Of Neurodegenerative Disease Active older people seem to have a lower risk of certain neurological disorders such as Alzheimer`s disease. A study published May 22 in the on-line edition of the Annals of Neurology, the research publication of... view more... (2002-05-15)
Improved estrogen reception may sharpen fuzzy memory
Estrogen treatments may sharpen mental performance in women with certain medical conditions, but University of Florida researchers suggest that recharging a naturally occurring estrogen receptor in the brain may also clear cognitive cobwebs. view more (2008-07-30)
Generation of a severe memory-deficit mutant mouse by exclusively eliminating the kinase activity of CaMKIIalpha
Ca2+/calmodulin-dependent protein kinase II alpha (CaMKII alpha) is an enzyme that adds phosphates to a variety of protein substrates to modify their functions. view more (2009-06-19)
Chemo drugs for treating breast cancer may cause changes in cognitive function
A new study investigating the effects of chemotherapy on cognitive function in mice has confirmed what many cancer patients receiving treatment have often complained about - a decline in their memory and other cognitive functions, sometimes characterized as "chemobrain". view more (2006-10-30)
Young adults at future risk of Alzheimer's have different brain activity, says study
Young adults with a genetic variant that raises their risk of developing Alzheimer's Disease show changes in their brain activity decades before any symptoms might arise. view more (2009-04-07)
Brain's cannabinoid system 'mellows' seizures
The same brain machinery that responds to the active substance in marijuana provides a central "on-demand" protection against seizures, researchers have found. They said their discoveries suggest that the "endocannabinoid" system might constitute a prime target for drugs against seizures of epilepsy and other neurodegenerative... view more... (2006-08-17)
How memories are made, and recalled
What makes a memory? Single cells in the brain, for one thing. For the first time, scientists at UCLA and the Weizmann Institute of Science in Israel have recorded individual brain cells in the act of calling up a memory, thus revealing where in the brain a specific memory is stored, and how it is able to recreate it. view more (2008-09-08)
Epilepsy marked by neural 'hub' network
An increased number of neuron "hubs" in the epileptic brain may be the root cause for the seizures that characterize the disorder, according to a UC Irvine study. view more (2008-03-26)
Life and death in the hippocampus: what young neurons need to survive
Whether newborn nerve cells in adult brains live or die depends on whether they can muscle their way into networks occupied by mature neurons. view more (2006-08-14)
Male seahorses like big mates
Male seahorses have a clear agenda when it comes to selecting a mating partner: to increase their reproductive success. view more (2009-07-08)
Researchers find alcoholics display abnormal brain activity when processing facial expressions
Researchers from Boston University School of Medicine (BUSM) have found that individuals who have a long history of alcoholism, but who have been abstinent for at least a month up to many years, showed abnormal brain activity when looking at facial expressions of others. view more (2009-08-11)
Newborn brain cells show the way
Although the fact that we generate new brain cells throughout life is no longer disputed, their purpose has been the topic of much debate. view more (2009-07-10)
Rutgers Scientists Discover Brain Cell Development Process Implicated in Mental Retardation, Finding May Lead to New Drug Therapies
Scientists at Rutgers, The State University of New Jersey, have discovered a biological process in brain cell development that may help explain some causes of mental retardation. This understanding may one day help other researchers develop therapies that can reduce specific forms of retardation. view more (2007-08-01)
Researchers discover that gene switches on during development of epilepsy
A discovery made by researchers at Wake Forest University School of Medicine while studying mice may help explain how some people without a genetic predisposition to epilepsy can develop the disorder. view more (2009-04-23)
Neurological effects of childhood sleep apnea
In this study, Ann Halbower and colleagues from Johns Hopkins University School of Medicine looked at 19 children aged 6-16 y with OSA and compared them with 12 healthy controls. view more (2006-08-22)
Multi-tasking adversely affects brain's learning, UCLA psychologists report
Multi-tasking affects the brain's learning systems, and as a result, we do not learn as well when we are distracted, UCLA psychologists report this week in the online edition of Proceedings of the National Academy of Sciences. view more (2006-07-26)
Septum keeps neurons in synch, can reduce epileptic seizures by 90 percent
The brain's septum helps prevent epileptic seizures by inducing rhythmical electrical activity in the circuits of another area of the brain known as the hippocampus, according to a new study in the Journal of Neurophysiology. view more (2006-06-20)
MRI study opens door to assessing, preventing dangerous brain iron levels
A magnetic resonance imaging (MRI) study at UCLA opens new doors to assessing and potentially preventing brain iron accumulation associated with risk of developing degenerative brain diseases such as Alzheimer's, Parkinson's and Dementia With Lewy Bodies. view more (2006-03-27)
