Paul Allen pledges $300 million to better understand the brain’s inner workings

Microsoft co-founder and billionaire Paul Allen is donating $300 million to his Allen Institute for Brain Science to fund new projects to map and observe the human brain and, in Allen’s words, “to one day understand the essence of what makes us human.” That brings the total amount Allen has invested in the Institute to half a billion.

Scripps scientists generate synthetic memory trace

Scripps Research Institute scientists and their colleagues have successfully harnessed neurons in mouse brains, allowing them to at least partially control a specific memory. Though just an initial step, the researchers hope such work will eventually lead to better understanding of how memories form in the brain, and possibly even to ways to weaken harmful thoughts for those with conditions such as schizophrenia and post traumatic stress disorder.

Scientists artificially derive brain stem cells from connective tissue of mice

These stem cells can reproduce and be converted into various types of brain cells. To date, only reprogramming in brain cells that were already fully developed or which had only a limited ability to divide was possible. The new reprogramming method presented by the Bonn scientists and submitted for publication in July 2011 now enables derivation of brain stem cells that are still immature and able to undergo practically unlimited division to be extracted from conventional body cells.

Study identifies abnormal brain gene expression patterns in autism

A study led by Eric Courchesne, PhD, director of the Autism Center of Excellence at the University of California, San Diego School of Medicine has, for the first time, identified in young autism patients genetic mechanisms involved in abnormal early brain development and overgrowth that occurs in the disorder. The findings suggest novel genetic and molecular targets that could lead to discoveries of new prevention strategies and treatment for the disorder.

Computer program could help dementia patients manage their disease

Researchers at Weill Cornell Medical College have developed a computer program that has tracked the manner in which different forms of dementia spread within a human brain. They say their mathematic model can be used to predict where and approximately when an individual patient's brain will suffer from the spread, neuron to neuron, of "prion-like" toxic proteins -- a process they say underlies all forms of dementia.

Alzheimer's may spread through connected neurons

Alzheimer's disease and other forms of dementia may spread within nerve networks in the brain by moving directly between connected neurons, instead of in other ways proposed by scientists, such as by propagating in all directions, according to researchers who report the finding in the March 22 edition of the journal Neuron.

Pannexins may contribute to symptoms related to IBD

Researchers from the Hotchkiss Brain Institute (HBI) and the Snyder Institute for Chronic Diseases at the University of Calgary's Faculty of Medicine have discovered a pathway that may contribute to the symptoms related to Crohn's disease and ulcerative colitis, collectively known as Inflammatory Bowel Disease.

Patients with tinnitus may soon have a definitive therapy

Clinical trials of the new therapy, called Acoustic Coordinated Reset (ACR), have shown that it reduces the loudness and annoyance caused by tinnitus in seven out of 10 patients.

Scans reveal Williams syndrome-associated personality/temperament traits

A personality profile marked by overly gregarious yet anxious behavior is rooted in abnormal development of a circuit hub buried deep in the front center of the brain, say scientists at the National Institutes of Health. They used three different types of brain imaging to pinpoint the suspect brain area in people with Williams syndrome, a rare genetic disorder characterized by these behaviors.

Study tests new method of sound simulation for treating tinnitus

A new clinical trial is to test whether a pocket-sized device that uses sound simulation to reboot faulty 'wiring' in the brain could cure people with the debilitating hearing disorder tinnitus.

Obesity gene mutation identified in mice

A new study has found why a mutation in a particular gene can lead to obesity. Mouse experiments suggested the body's message to “stop eating” was blocked if the animals had the mutation. The study, published in Nature Medicine, said the brain's response to appetite hormones was being disrupted.

Scientists investigate molecular mechanism of memory encoding in neurons

University of Alberta led research may have discovered how memories are encoded in our brains. Scientists understand memory to exist as strengthened synaptic connections among neurons. However components of synaptic membranes are relatively short-lived and frequently re-cycled while memories can last a lifetime.

Study reveals how Bdnf gene mutation contributes to severe obesity

Researchers at Georgetown University Medical Center have revealed how a mutation in a single gene is responsible for the inability of neurons to effectively pass along appetite suppressing signals from the body to the right place in the brain. What results is obesity caused by a voracious appetite.

PCP signaling restricts neural growth during regeneration, homeostasis and development

The genetic pathway that regulates the way cells align themselves relative to each other has been found to act as a "stop sign" that signals organisms when to halt cell growth, according to new research published by biologists at the Center for Regenerative and Developmental Biology in Tufts University's School of Arts and Sciences.

Eight European research institutes partner to provide training on systemic neuroscience

Eight European research institutes, including Johannes Gutenberg University Mainz (JGU), and three commercial partners have joined forces in an EU project to provide young academics with an outstanding research environment in the field of systemic neuroscience.

GABA neurons could help restore muscle coordination deficits of Huntington's

Huntington's disease, the debilitating congenital neurological disorder that progressively robs patients of muscle coordination and cognitive ability, is a condition without effective treatment, a slow death sentence. But if researchers can build on new research reported this week in the journal Cell Stem Cell, a special type of brain cell forged from stem cells could help restore the muscle coordination deficits that cause the uncontrollable spasms characteristic of the disease.
