fMRI scans can identify biological signs of autism in toddlers

The biological causes of autism are still not understood. A diagnosis of autism is only possible after ages three or four and the tests are subjective, based on behavioral symptoms. Now, in research that appeared in Neuron, scientists at the Weizmann Institute of Science, Carnegie Mellon University, and the University of California, San Diego have found, for the first time, a method that can accurately identify a biological sign of autism in very young toddlers.

Insight into Fragile X Syndrome and autism

Researchers now have a much clearer understanding of how mutations in a single gene can produce the complex cognitive deficits characteristic of Fragile X Syndrome, the most common inherited form of intellectual disability.

Computer modeling to predict how peripheral nerve axon responds to electrical stimuli

Researchers at Case Western Reserve University have developed a computer modeling method to accurately predict how a peripheral nerve axon responds to electrical stimuli, slashing the complex work from an inhibitory weeks-long process to just a few seconds.

Intense visual stimulation renders nerve cells more receptive to subsequent learning

Dr. Ed Ruthazer is a mapmaker but, his landscape is the developing brain - specifically the neuronal circuitry, which is the network of connections between nerve cells. His research at The Montreal Neurological Institute and Hospital - The Neuro at McGill University, reveals the brain as a dynamic landscape where connections between nerves are plastic, changing and adapting to the demands of the environment.

Study: 'The wave of death' may not indicate onset of brain death

The wave-shaped signal, which was previously dubbed 'the wave of death', had already been measured by researchers in Nijmegen in the brains of rats that had just been decapitated. The rats had already had electrodes implanted in their brains before the experiment.

Autism Speaks honors Scripps Research scientist with Weatherstone Fellowship

Autism Speaks, the nation's largest autism science and advocacy group, has awarded a two-year Dennis Weatherstone Pre-Doctoral Fellowship to Kristopher Nazor of The Scripps Research Institute.

New method to study neuronal activity in the deepest layers of the cortex

Visual and tactile objects in our surroundings are translated into a perception by complex interactions of neurons in the cortex. The principles underlying spatial and temporal organization of neuronal activity during decision-making and object perception are not all understood yet.

Scientists study neuronal excitation to treat neurological disorders

Oh, the challenges of being a neuron, responsible for essential things like muscle contraction, gland secretion and sensitivity to touch, sound and light, yet constantly bombarded with signals from here, there and everywhere.

New technique may help scientists probe mysteries of many different stem cells

Researchers at the Salk Institute have been able to genetically incorporate "unnatural" amino acids, such as those emitting green fluorescence, into neural stem cells, which then differentiate into brain neurons with the incandescent "tag" intact.

Scientists identify molecular mechanism behind alcohol-induced blackouts

A person who drinks too much alcohol may be able to perform complicated tasks, such as dancing, carrying on a conversation or even driving a car, but later have no memory of those escapades. These periods of amnesia, commonly known as "blackouts," can last from a few minutes to several hours.

Alpha-tocotrienol protects brain cells after stroke in three ways

A natural form of vitamin E called alpha-tocotrienol can trigger production of a protein in the brain that clears toxins from nerve cells, preventing those cells from dying after a stroke, new research shows.

Prolonged exposure to air pollution can have visible, negative effects on brain

Long-term exposure to air pollution can lead to physical changes in the brain, as well as learning and memory problems and even depression, new research in mice suggests.

U-M researchers a step closer to developing treatments for aging and chronic diseases

As our bodies first form, developing cells are a lot like children put on the school bus with their names and addresses pinned to their shirts. The notes identify one as a future heart cell, another as a liver cell, a third as a neuron. And that's what they each grow up to be. But once those cells reach adulthood, changes to those original marching orders caused by aging, disease and other stressors like smoking can precipitate a kind of identity crisis, researchers at the University of Michigan Health System have found.

Erratic investment responses can make a smart portfolio richer

Playing the stock market can be a risky game. And when the market behaves unpredictably, public fear can lead to erratic investment responses and market chaos.

Brain stem cells shown to generate multiple new brain stem cells

A Johns Hopkins team has discovered in young adult mice that a lone brain stem cell is capable not only of replacing itself and giving rise to specialized neurons and glia – important types of brain cells – but also of taking a wholly unexpected path: generating two new brain stem cells.

Study shows how binge drinking could cause serious brain damage in young adults

It's considered a rite of passage among young people - acting out their independence through heavy, episodic drinking. But a new University of Cincinnati study, the first of its kind nationally, is showing how binge drinking among adolescents and young adults could be causing serious damage to a brain that's still under development at this age.

Scientists identify central switch responsible for epilepsy

UC Irvine and French researchers have identified a central switch responsible for the transformation of healthy brain cells into epileptic ones, opening the way to both treat and prevent temporal lobe epilepsy.

New research helps explain how memories are stored at synapses

Have a tough time remembering where you put your keys, learning a new language or recalling names at a cocktail party? New research from the Lisman Laboratory at Brandeis University points to a molecule that is central to the process by which memories are stored in the brain. A paper published in the June 22 issue of the Journal of Neuroscience describes the new findings.

FDA grants Fast Track designation for Repligen's RG3039 to treat Spinal Muscular Atrophy

Repligen Corporation announced today that the U.S. Food and Drug Administration (FDA) has granted Fast Track designation for RG3039, a potential treatment for Spinal Muscular Atrophy.

New surprising details about flow of neurotransmitters between brain neurons

Two studies featuring research from Weill Cornell Medical College have uncovered surprising details about the complex process that leads to the flow of neurotransmitters between brain neurons -- a dance of chemical messages so delicate that missteps often lead to neurological dysfunction.
