Neuroscientist to discuss teenage brain development at AAAS meeting in California

Teenage exploration and risk taking could be explained by dramatic changes in the brain that allow elaborate planning and are driven by the need for immediate reward, according to a University of Pittsburgh neuroscientist who will be talking about her research in a panel discussion and press briefing at the American Association for the Advancement of Science annual meeting, Feb. 13 to 16, in San Jose, Calif.

Study shows amyloid formation may link type 2 diabetes and Alzheimer disease

The pathological process amyloidosis, in which misfolded proteins (amyloids) form insoluble fibril deposits, occurs in many diseases, including Alzheimer disease (AD) and type 2 diabetes mellitus (T2D).

New Penn Medicine study reveals how sleep deprivation increases intake of fat

Experts have warned for years that insufficient sleep can lead to weight gain. A new Penn Medicine study found that not only do we consume more food following a night of total sleep deprivation, but we also we consume more fat and less carbohydrates and a region of the brain known as the salience network is what may lead us to eat more fat.

Mindfulness training can influence health via stress reduction pathways

Over the past decade, there have been many encouraging findings suggesting that mindfulness training can improve a broad range of mental and physical health problems. Yet, exactly how mindfulness positively impacts health is not clear.

Adolescents meth abusers suffer greater alterations in their brain than adult drug abusers

Adolescents who chronically use methamphetamine suffer greater and more widespread alterations in their brain than adults who chronically abuse the drug-and damage is particularly evident in a part of the brain believed to control the "executive function," researchers from the University of Utah and South Korea report.

UC San Diego School of Medicine project receives 2015 Avant-Garde Award for HIV/AIDS Research

A University of California, San Diego School of Medicine project involving the creation of miniature models of the human brain - developed with stem cells - to study neurological disorders caused by HIV and methamphetamine use has been named one of five recipients of the 2015 Avant-Garde Award for HIV/AIDS Research from the National Institute on Drug Abuse.

Five researchers selected to receive 2015 Avant-Garde Award for HIV/AIDS Research

With proposals ranging from innovative therapies to the development of unique organoid models of the brain, five scientists have been selected to receive the 2015 Avant-Garde Award for HIV/AIDS Research from the National Institute on Drug Abuse, part of the National Institutes of Health. The five scientists will each receive $500,000 per year for five years to support their research.

Researchers report that neurons in the brain are connected like a social network

Neurons in the brain are wired like a social network, report researchers from Biozentrum, University of Basel. Each nerve cell has links with many others, but the strongest bonds form between the few cells most similar to each other.

Brain scans can predict therapeutic responses to talk therapy

UNC School of Medicine researchers have shown that brain scans can predict which patients with clinical depression are most likely to benefit from a specific kind of talk therapy.

SuperAgers have distinctly different looking brains

SuperAgers, aged 80 and above, have distinctly different looking brains than those of normal older people, according to new Northwestern Medicine research that is beginning to reveal why the memories of these cognitively elite elders don't suffer the usual ravages of time.

Researchers successfully monitor expression of genes in neurons

Gene expression within neurons is critical for the formation of memories, but it's difficult to identify genes whose expression is altered by learning. Now researchers have successfully monitored the expression of genes in neurons after rats were exposed to auditory fear conditioning, in which a neutral auditory tone is paired with electric shock.

Scientists reveal mechanism underlying cellular degeneration of upper motor neurons

For the first time, scientists have revealed a mechanism underlying the cellular degeneration of upper motor neurons, a small group of neurons in the brain recently shown to play a major role in ALS pathology.

People who carry longevity gene variant have larger brain region

People who carry a variant of a gene that is associated with longevity also have larger volumes in a front part of the brain involved in planning and decision-making, according to researchers at UC San Francisco.

Improving prefrontal cortex activity could help autistic people regulate emotions

Tantrums, irritability, self-injury, depression, anxiety. These symptoms are associated with autism, but they're not considered core symptoms of the disorder. Researchers from the UNC School of Medicine are challenging this assertion. They have used functional MRI to show that - when it comes to the ability to regulate emotions - brain activity in autistic people is significantly different than brain activity in people without autism.

Large numbers of boys suffer from cognitive disabilities linked to lead than girls

A study recently published in the Journal of Environmental Health provides evidence the female hormones estrogen and estradiol may help ward off the effects of lead exposure for young girls, explaining why boys, in greater numbers than girls, are shown to suffer from the cognitive disabilities linked to lead.

International study identifies genetic factors that influence the size of brain structures

An international study, which included researchers from NUI Galway, has identified significant genetic factors that influence the size of structures within the brain. It is hoped these new insights may help scientists better understand disorders such as schizophrenia, Alzheimer's disease and epilepsy.

UCLA researchers find new treatment that restores normal social behavior in autism mice model

Among the problems people with Autism spectrum disorders (ASD) struggle with are difficulties with social behavior and communication. That can translate to an inability to make friends, engage in routine conversations, or pick up on the social cues that are second nature to most people. Similarly, in a mouse model of ASD, the animals, like humans, show little interest in interacting or socializing with other mice.
