Predicting Alzheimer’s Disease With Blood Tests: Early Detection, Ethical Concerns

December 4, 2014 8:46 am | by Stephanie Guzowski, Editor, Drug Discovery & Development | Articles | Comments

If you could take a blood test that could detect — with nearly 100% accuracy — whether you were genetically destined to get Alzheimer’s disease, would you take that test? Read more...                     

Disentangling the Dopaminergic System

December 3, 2014 3:55 pm | News | Comments

Though dopamine neurons influence many diverse behaviors and diseases, scientists have historically presumed that all of these important nerve cells are molecularly similar within two clusters of the brain. In a new study, Northwestern Medicine scientists prove that premise wrong by identifying several molecularly distinct subtypes of dopamine neurons within each cluster. Read more...

Scientists Detect Brain Network That Gives Humans Superior Reasoning Skills

December 3, 2014 3:18 pm | by Yasmin Anwar, UC Berkeley | News | Comments

UC Berkeley scientists have found mounting brain evidence that helps explain how humans have excelled at “relational reasoning,” a cognitive skill in which we discern patterns and relationships to make sense of seemingly unrelated information, such as solving problems in unfamiliar circumstances. Read more...

Brain Activity after Smokers Quit Predicts Chances of Relapsing

December 3, 2014 2:57 pm | News | Comments

Quitting smoking sets off a series of changes in the brain that Penn Medicine researchers say may better identify smokers who will start smoking again—a prediction that goes above and beyond today’s clinical or behavioral tools for assessing relapse risk. Read more...

Learning a Second Language: First-Rate Exercise for the Brain

December 3, 2014 8:30 am | by Bioscience Technology Staff | Articles | Comments

The brain is so exquisitely sensitive to language that it only takes six weeks of learning Chinese for the neurons of English speakers to rewire. And those whose brains are fully bilingual are more facile at learning generally.

Stickleback Leaders are Stickleback Loners

December 2, 2014 12:25 pm | Videos | Comments

Research reveals that sticklebacks with bolder personalities are not only better leaders but also less sociable than more timid fish. The behavior of these bolder fish shapes the dynamics of the group.              

Imaging Shows Connection Breakdown in Early Alzheimer’s Brains

December 1, 2014 1:05 pm | News | Comments

Changes in brain connections visible on MRI could represent an imaging biomarker of Alzheimer's disease, according to a new study. For the new study, researchers looked at the brain's structural connectome, a map of white matter tracts that carry signals between different areas of the brain.

Reading Harry Potter Gives Clues to Brain Activity

December 1, 2014 8:30 am | by Lauran Neergaard - AP Medical Writer - Associated Press | News | Comments

Harry Potter swoops around on his broom, faces the bully Malfoy and later runs into a three-headed dog. For scientists studying brain activity while reading, it's the perfect excerpt from the young wizard's many adventures to give their subjects. 

New Studies Show Anxiety, Depression, Guilt Harm the Brain

November 26, 2014 8:30 am | by Bioscience Technology Staff | Articles | Comments

Two studies in recent weeks have found that anxiety, depression and guilt can physically change and damage the brain from preschool through adulthood.                            

Google's Latest: A Spoon That Steadies Tremors

November 26, 2014 8:30 am | by By Martha Mendoza - AP National Writer - Associated Press | News | Comments

Google is throwing its money, brain power and technology at the humble spoon. But these spoons are a bit more than your basic utensil: Using hundreds of algorithms, they allow people with essential tremors and Parkinson's disease to eat without spilling.

November 26, 2014 8:30 am | Videos | Comments

An interdisciplinary team of scientists has convened to map the origins of mental illnesses in the brain and develop noninvasive technologies to treat the conditions.                        

Brain Scans Help Tailor Alcoholism Treatment

November 25, 2014 2:38 pm | News | Comments

Clinical research is using brain imaging and drug therapy to better understand how microscopic changes in brain connectivity relate to alcohol dependence and recovery.                        

Creating Pain-sensing Neurons

November 25, 2014 2:11 pm | News | Comments

After more than six years of intensive effort, including repeated failures that at times made the quest seem futile, researchers have successfully converted mouse and human skin cells into pain-sensing neurons that respond to a number of stimuli.  

Brain Protein Linked to Sleep May be Alzheimer’s Prevention Target

November 25, 2014 2:02 pm | News | Comments

A protein that stimulates the brain to awaken from sleep may be a target for preventing Alzheimer’s disease, according to a new study. In recent years, scientists have established links between sleep problems and Alzheimer’s.      

Computer Games Could Prevent Falls in the Elderly

November 24, 2014 12:22 pm | News | Comments

A research team has developed new computer games designed to significantly reduce the likelihood of falls at home and in the community among older people.                            

Test Detects Early Brain Damage in Football Players
