Scientists Boost Memory by Stimulating Key Site in Brain
Mechanism holds potential for improving recall in dementia patients. Have you ever gone to the movies and forgotten where you parked the car? New UCLA research may one day help you improve your memory. UCLA neuroscientists have demonstrated that they can strengthen memory [Read More]
Molecular Path from Internal Clock to Cells Controlling Rest and Activity Revealed
The molecular pathway that carries time-of-day signals from the body’s internal clock to ultimately guide daily behavior is like a black box, says Amita Sehgal, PhD, the John Herr Musser Professor of Neuroscience and Co-Director, Comprehensive Neuroscience Center, at [Read More]
Patients’ Brains May Adapt to ADHD Medication
New research reveals how the brain appears to adapt to compensate for the effects of long-term ADHD medication, suggesting why ADHD medication is more effective short-term than it is long-term. The study, from the Institute of Psychiatry (IoP) at King’s College London is [Read More]
Mom’s Love Good for Child’s Brain
School-age children whose mothers nurtured them early in life have brains with a larger hippocampus, a key structure important to learning, memory and response to stress. The new research, by child psychiatrists and neuroscientists at Washington University School of [Read More]
Making Memories Last
Stowers researchers discovered that a prion-like protein plays a key role in storing long-term memories. Memories in our brains are maintained by connections between neurons called “synapses”. But how do these synapses stay strong and keep memories alive for decades? [Read More]
Study: Men at Higher Risk for Mild Memory Loss than Women
Men may be at higher risk of experiencing mild cognitive impairment (MCI), or the stage of mild memory loss that occurs between normal aging and dementia, than women, according to a study published in the January 25, 2012, online issue of Neurology®, the medical journal of [Read More]
Genetic Study Offers Clues to How Intelligence Changes Through Life
Scientists have estimated for the first time the extent to which genes determine changes in intelligence across the human life course. The study found that genetic factors may account for about 24 per cent of changes in intelligence between childhood and old age. The [Read More]
Walk This Way: Scientists and MBL Physiology Course Students Describe How a Motor Protein “Steps Out”
Just like people, some proteins have characteristic ways of “walking,” which (also like human gaits) are not so easy to describe. But now scientists have discovered the unique “drunken sailor” gait of dynein, a protein that is critical for the function of every cell [Read More]
Cognitive Decline Can Begin as Early as 45, Warn Experts
The brain’s capacity for memory, reasoning and comprehension skills (cognitive function) can start to deteriorate from age 45, finds research published in the BMJ today. Previous research suggests that cognitive decline does not begin before the age of 60, but this view [Read More]
GABA Signaling Prunes Back Copious Provisional Synapses During Neural Circuit Assembly
Quite early in its development, the mammalian brain has all the raw materials on hand to forge complex neural networks. But forming the connections that make these intricate networks so exquisitely functional is a process that occurs one synapse at a time. An important [Read More]
