New marker for raised intracranial pressure
Magnetic resonance imaging (MRI) measurements of the thickness of the optic nerve sheath are a good marker for raised intracranial pressure (ICP).   view more (2008-09-11)

Why delaying gratification is smart: A neural link between intelligence and self-control
If you had a choice between receiving $1,000 right now or $4,000 ten years from now, which would you pick? Psychologists use the term "delay discounting" to describe our inability to resist the temptation of a smaller immediate reward in lieu of receiving a larger reward at a later date.   view more (2008-09-10)

Protein found that regulates gene critical to dopamine-releasing brain cells
Researchers have identified a protein they say appears to be a primary player in maintaining normal functioning of an important class of neurons - those brain cells that produce, excrete and then reabsorb dopamine neurotransmitters.   view more (2008-09-10)

Abuse of painkillers can predispose adolescents to lifelong addiction
No child aspires to a lifetime of addiction. But their brains might. In new research to appear online in the journal Neuropsychopharmacology this week, Rockefeller University researchers reveal that adolescent brains exposed to the painkiller Oxycontin can sustain lifelong and permanent changes in... view more (2008-09-10)

Fluctuations in serotonin transport may explain winter blues
Why do many Canadians get the winter blues? In the first study of its kind in the living human brain, Dr. Jeffrey Meyer and colleagues at the Centre for Addiction and Mental Health (CAMH) have discovered greater levels of serotonin transporter in the brain in winter than in summer.   view more (2008-09-09)

Researchers seeking to identify Alzheimer's risk focus on specific blood biomarker
A simple blood test to detect whether a person might develop Alzheimer's disease is within sight and could eventually help scientists in their quest toward reversing the disease's onset in those likely to develop the debilitating neurological condition.   view more (2008-09-09)

3T MRI leads to better diagnosis for focal epilepsy
3T MRI is better at detecting and characterizing structural brain abnormalities in patients with focal epilepsy than 1.5T MRI, leading to a better diagnosis and safer treatment of patients, according to a recent study conducted at the Oregon Health and Science University in Portland, OR.   view more (2008-09-08)

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... view more (2008-09-08)

TAU Researchers Create New Stem Cell Screening Tool
Stem cell research is the next great leap in medicine. In the future, new tissue grown in a laboratory could replace a failing heart, or new cells take the place of damaged cells in the brain.   view more (2008-09-05)

Rhode Island Hospital study finds link between obesity, type 2 diabetes and neurodegeneration
New research from Rhode Island Hospital found that obesity and Type 2 Diabetes Mellitus (T2DM) can contribute to mild neurodegeneration with features common with Alzheimer's disease (AD) - the first study to show that obesity can cause neurodegeneration.   view more (2008-09-05)

Gene enhancer in evolution of human opposable thumb
Scientists have discovered a gene enhancer, known as HACNS1, that may have contributed to the evolution of the uniquely opposable human thumb, and possibly also modifications in the ankle or foot that allow humans to walk on two legs.   view more (2008-09-05)

Thumbs up -- a tiny ancestral remnant lends developmental edge to humans
Subtle genetic changes that confer an evolutionary advantage upon a species, such as the dexterity characteristic of the human hand, while difficult to detect and even harder to reproduce in a model system, have nevertheless generated keen interest amongst evolutionary biologists.   view more (2008-09-05)

Arteries from distinct regions of the body have unique immune functions
Human arteries play distinct roles in the immune system depending on their anatomical location, researchers at Emory University School of Medicine have discovered.   view more (2008-09-04)

Gene associated with pair-bonding in animals has similar effects in human males
Variation in the gene for one of the receptors for the hormone vasopressin appears to be associated with how human males bond with their partners, according to an international team of researchers.   view more (2008-09-04)

Yerkes researchers create animal model of chronic stress
In an effort to better understand how chronic stress affects the human body, researchers at the Yerkes National Primate Research Center and the Department of Psychiatry and Behavioral Sciences, Emory University, have created an animal model that shows how chronic stress affects behavior, physiology... view more (2008-09-04)

New methods identify and manipulate 'newborn' cells in animal model of Parkinson's disease
When cells in the brain are lost through disease or injury, neighboring cells begin to divide and multiply, but only a few areas in the brain are able to produce new neurons.   view more (2008-09-04)

Neuroscientist scans brain for clues on best time to multitask
In today's fast-paced world, multitasking has become an increasingly necessary part of our daily routine. Unfortunately, multitasking also is notoriously inefficient. However, a new brain imaging study led by a cognitive neuroscientist at the University of New Hampshire finds that there are optimal... view more (2008-09-03)

New study finds that add-on therapy improves depressive symptoms in bipolar disorder
Lingering depression is a serious and common problem in bipolar disorder, and does not resolve well with existing treatments.   view more (2008-09-03)

Gene is likely cause of stroke-inducing vascular malformations
UCSF scientists have discovered that a gene controlling whether blood vessels differentiate into arteries or veins during embryonic development is linked to a vascular disorder in the brain that causes stroke.   view more (2008-09-03)

Brain imaging links chronic insomnia to reversible cognitive deficits without changes in behavior
A neuroimaging study in the Sept. 1 issue of the journal Sleep is the first to find that cognitive processes related to verbal fluency are compromised in people with insomnia despite the absence of a behavioral deficit.   view more (2008-09-02)

Playing, and even watching, sports improves brain function
Being an athlete or merely a fan improves language skills when it comes to discussing their sport because parts of the brain usually involved in playing sports are instead used to understand sport language, new research at the University of Chicago shows.   view more (2008-09-02)

PET scans help identify mechanism underlying seasonal mood changes
Brain scans taken at different times of year suggest that the actions of the serotonin transporter-involved in regulating the mood-altering neurotransmitter serotonin-vary by season, according to a report in the September issue of Archives of General Psychiatry, one of the JAMA/Archives journals.   view more (2008-09-02)

Study finds B-vitamin deficiency may cause vascular cognitive impairment
A deficiency of B-vitamins may cause vascular cognitive impairment, according to a new study. Researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging (HNRCA) at Tufts University used an experimental model to examine the metabolic, cognitive, and microvascular effects of dietary... view more (2008-09-02)

Rapid changes in key Alzheimer's protein described in humans
For the first time, researchers have described hour-by-hour changes in the amount of amyloid beta, a protein that is believed to play a key role in Alzheimer's disease, in the human brain.   view more (2008-08-29)

Barrow researchers identify a new approach to detect the early progression of brain tumors
Researchers at Barrow Neurological Institute at St. Joseph's Hospital and Medical Center recently participated in a pilot study with the Montreal Neurological Institute that suggests a certain type of MRI scanning can detect when a patient is failing brain tumor treatment before symptoms appear.   view more (2008-08-29)
