Stanford scientists have shown how the brain changes throughout life, and created a standard curve that can be used to assess whether patients are maturing and aging normally. This resource could help diagnose or monitor people with mental health conditions, learning delays or other diseases.
We can witness our bodies mature, then gradually…[Read more]
Neuroscience News wrote a new post, Researchers Reveal Pathway that Contributes to Alzheimer’s Disease, on the site Neuroscience News 18 hours, 30 minutes ago
Researchers at Jacksonville’s campus of Mayo Clinic have discovered a defect in a key cell-signaling pathway they say contributes to both overproduction of toxic protein in the brains of Alzheimer’s disease patients as well as loss of communication between neurons — both significant contributors to this type of dementia.
Their study, in the…[Read more]
Neuroscience News wrote a new post, Researchers Link Gene to Increased Dendritic Spines; A Signpost of Autism, on the site Neuroscience News 19 hours, 1 minute ago
By deleting the NrCAM gene, scientists have found a potential way to cut back on the neural connections implicated in Autism Spectrum Disorder.
Scientists at the UNC School of Medicine have discovered that knocking out the gene NrCAM leads to an increase of dendritic spines on excitatory pyramidal cells in the brains of mammals. Other studies…[Read more]
For years, neuroscientists have been trying to develop tools that would allow them to clearly view the brain’s circuitry in action—from the first moment a neuron fires to the resulting behavior in a whole organism. To get this complete picture, neuroscientists are working to develop a range of new tools to study the brain. Researchers at Caltech…[Read more]
Spontaneous mutations in key brain gene are a cause of the disorder.
Disorders such as autism are often caused by genetic mutations. Such mutations can change the shape of protein molecules and stop them from working properly during brain development. However, the genetic foundation of autism is complicated and there is no single genetic cause.…[Read more]

Scientists uncover the neural basis of confidence in the rat brain.
Life is a series of decisions, ranging from the mundane to the monumental. And each decision is a gamble, carrying with it the chance to second-guess. Did I make the right turn at that light? Did I choose the right college? Was this the right job for me?
Our desire to…[Read more]

Researchers at University of California, San Diego School of Medicine have identified a control mechanism for an area of the brain that processes sensory and emotive information that humans experience as “disappointment.”
The discovery of what may effectively be a neurochemical antidote for feeling let-down is reported Sept. 18 in the online…[Read more]
Researchers at the University of Alabama at Birmingham report the discovery of a novel mechanism in the brain involved in the formation of memory and learning. In findings reported online this week in Nature, the research team describes the role of a histone subunit known as H2A.Z.
The discovery could have therapeutic ramifications for…[Read more]
Study led by NYU Langone Medical Center bolsters support for new, personalized approaches to treating PTSD and other trauma-based disorders.
In a novel brain-imaging study among trauma victims, researchers at NYU Langone Medical Center have linked an opioid receptor in the brain — associated with emotions — to a narrow cluster of trauma…[Read more]
Neuroscience News wrote a new post, Lack of Facial Expression Leads to Perceptions of Unhappiness, on the site Neuroscience News 2 days, 19 hours ago
People with facial paralysis are perceived as being less happy simply because they can’t communicate in the universal language of facial expression, a new study from an Oregon State University psychology professor shows.
The findings highlight the important role the face plays in everyday communication and indicates people may hold a prejudice…[Read more]
Neuroscience News wrote a new post, Study Links Physical Activity in Older Adults to Brain White Matter Integrity, on the site Neuroscience News 2 days, 20 hours ago
Like everything else in the body, the white-matter fibers that allow communication between brain regions also decline with age. In a new study, researchers found a strong association between the structural integrity of these white-matter tracts and an older person’s level of daily activity – not just the degree to which he or she engaged in…[Read more]

Overindulging in high-calorie snacks is partly caused by lapses in a very specific part of the brain, according to a new University of Waterloo study.
The study, published in Psychosomatic Medicine: Journal of Biobehavioral Medicine, is the first to conclusively link reduced operation of the dorsolateral prefrontal cortex with self-restraint in…[Read more]
Findings may lead to new therapies for sleep disorders, including insomnia.
A sleep-promoting circuit located deep in the primitive brainstem has revealed how we fall into deep sleep. Discovered by researchers at Harvard School of Medicine and the University at Buffalo School of Medicine and Biomedical Sciences, this is only the second “sleep…[Read more]
Researchers have found evidence that genetic factors may contribute to the development of language during infancy.

While abnormalities in the adrenergic and noradrenergic systems, both integral in the fight-or-flight response, are thought to play a role in the development of post-traumatic stress disorder (PTSD), until now there has been no genetic evidence of this connection. A collaborative study just released by researchers at Columbia University’s Mailman…[Read more]
