Virtual Brain Lab Brings Together World-leading Neuroscientists

Twenty-one leading neuroscience groups from around the world, including seven from UCL, have formed a "virtual brain lab" to test how the brain controls learning and decision making. The £10 million International Brain Lab brings together groups from UK, USA, France, Switzerland and Portugal to uncover how complex networks of brain cells support our ability to

Common Growth Factor in Brain Might Slow Cognitive Decline

Fri, 01/29/2016 - 8:49am Bevin Fletcher, Associate Editor, BioScience Technology With age, often comes mental decline, but a new study published in Neurology this week points to potential neuroprotective effects from a common growth factor in the brain. Researchers led by Aron S. Buchman, M.D. of Rush University Medical Center in Chicago examined the role

Jammed Up Cellular Highways May Initiate Dementia and ALS

Molecular therapy partially relieves havoc wreaked by gene mutation in human and fly cells August 26, 2015 FAST FACTS: The C9orf72 mutation is the most common known genetic risk factor for 40 percent of inherited cases of amyotrophic lateral sclerosis (ALS) and a similar percentage of inherited cases of frontotemporal dementia. Researchers say they have

X-ray laser experiment could help in designing drugs for brain disorders

August 20, 2015 Scientists found that when two protein structures in the brain join up, they act as an amplifier for a slight increase in calcium concentration, triggering a gunshot-like release of neurotransmitters from one neuron to another. AUG 20, 2015 In the foreground of the illustration, two combined protein complexes — SNARE, shown in blue,

Scientists Find What Controls Waking Up and Going to Sleep

Simple two-cycle mechanism turns key brain neurons on or off during 24-hour day August 13, 2015 | by Megan Fellman Ravi Allada EVANSTON, Ill. --- Fifteen years ago, an odd mutant fruit fly caught the attention and curiosity of Dr. Ravi Allada, a circadian rhythms expert at Northwestern University, leading the neuroscientist to recently discover

Chemical Cocktails Produce Neurons

Two research groups have devised small-molecule recipes to directly transform fibroblasts into neurons. By Kerry Grens | August 6, 2015 COURTESY OF HONGKUI DENG Over the past several years, scientists have been in hot pursuit of finding an efficient way to directly transform skin cells to brain cells—skipping an intermediate pluripotent step. Genetic approaches have

Device delivers drugs to brain via remote control​​

Technology demonstrated for the first time in mice July 16, 2015 By Jim Dryden ALEX DAVID JEREZ ROMAN PHOTO Tiny, implantable devices are capable of delivering light or drugs to specific areas of the brain, potentially improving drug delivery to targeted regions of the brain and reducing side effects. Eventually, the devices may be used

Alzheimer’s Affects Black and White Brains Differently, Study Says

Thu, 07/16/2015 - 8:59am Seth Augenstein, Digital Reporter Alzheimer’s disease causes deteriorating changes in the brain. But those changes may be different for people of different races, according to a new study released today. Three-quarters of African-American Alzheimer’s patients analyzed post-mortem were found to have a mingling of the plaques and tangles representative of the

Futuristic brain probe allows for wireless control of neurons

NIH-funded scientists developed an ultra-thin, minimally invasive device for controlling brain cells with drugs and light A study showed that scientists can wirelessly determine the path a mouse walks with a press of a button. Researchers at the Washington University School of Medicine, St. Louis, and University of Illinois, Urbana-Champaign, created a remote controlled, next-generation

Injectable nanoelectronics for treatment of neuro-degenerative diseases

June 8, 2015 - Harvard UniversityIt's a notion that might be pulled from the pages of science-fiction novel - electronic devices that can be injected directly into the brain, or other body parts, and treat everything from neurodegenerative disorders to paralysis. It sounds unlikely, until you visit Charles Lieber's lab. A team of international researchers,
