Defects in schizophrenia-risk genes and environmental stress lead to abnormal brain development

Working with genetically engineered mice and the genomes of thousands of people with schizophrenia, researchers at Johns Hopkins say they now better understand how both nature and nurture can affect one's risks for schizophrenia and abnormal brain development in general.

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.

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.

Study identifies function of GlialCAM gene in brain edema

A study of the pathophysiology of this rare disease has uncovered one mechanism that destabilizes the homeostatic balance of brain cells causing edema.

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.

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.

Scientists use novel system to discover sequential firing of neurons

Princeton University researchers have used a novel virtual reality and brain imaging system to detect a form of neural activity underlying how the brain forms short-term memories that are used in making decisions.

Closer to solving how 100 billion cells are created, each with specific duties

How are 100 billion cells created, each with specific duties? The human brain is evidence that nature can achieve this. Researchers at Link-ping University in Sweden have now taken a step closer to solving this mystery.

OPKO Health, Scripps Research partner to commercialize Parkinson's disease compound, SR 3306

The Scripps Research Institute and OPKO Health, Inc. today announced a global agreement for the development and commercialization of SR 3306, a novel compound discovered by scientists from the Florida campus of The Scripps Research Institute that blocks the destruction of brains cells in animal models of Parkinson's disease.

TSRI, OPKO Health to develop and commercialize SR 3306 for Parkinson's

OPKO Health, Inc. and The Scripps Research Institute today announced a global agreement for the development and commercialization of SR 3306, a novel compound discovered by scientists from the Florida campus of The Scripps Research Institute that blocks the destruction of brains cells in animal models of Parkinson's disease.

Gene that causes aggression in men under stress discovered

Scientists have found that “macho” gene that makes men behave more aggressively than women under stress. They say this one gene could explain why men have a 'fight or flight' response while women are more likely to try and defuse the situation. The study has been published in the journal BioEssays.

Biologists identify how and where the brain processes FM sweeps

In both animals and humans, vocal signals used for communication contain a wide array of different sounds that are determined by the vibrational frequencies of vocal cords. For example, the pitch of someone's voice, and how it changes as they are speaking, depends on a complex series of varying frequencies. Knowing how the brain sorts out these different frequencies-which are called frequency-modulated (FM) sweeps-is believed to be essential to understanding many hearing-related behaviors, like speech.

Scientists identify 2,000 important genes linked to singing

Can the song of a small bird provide valuable insights into human stuttering and speech-related disorders and conditions, including autism and stroke? New research by UCLA life scientists and colleagues provides reason for optimism.

Loss of glutamate receptor linked to negative effects of chronic stress

Chronic stress has a more powerful effect on the brain during adolescence than in adulthood and now there's proof at the molecular level, according to findings published in Neuron by University at Buffalo researchers.

Deafness penetrates more rapidly and deeply into the brain than previously thought

Portions of a songbird's brain that control how it sings have been shown to decay within 24 hours of the animal losing its hearing.

Study uncovers neural mechanism that links repeated stress with impaired memory

Anyone who has ever been subject to chronic stress knows that it can take a toll on emotions and the ability to think clearly. Now, new research uncovers a neural mechanism that directly links repeated stress with impaired memory.

Deficits in mirror neuron system contribute to social impairments in ASD

Impaired social function is a cardinal symptom of autism spectrum disorders (ASDs). One of the brain circuits that enable us to relate to other people is the "mirror neuron" system. This brain circuit is activated when we watch other people, and allows our brains to represent the actions of others, influencing our ability to learn new tasks and to understand the intentions and experiences of other people.
