Researchers have developed a new screening method to diagnose autism, which unlike current methods does not rely on subjective criteria. These results are published in a series of studies in the open-access journal Frontiers in Neuroscience.

Going to bed at different times every night throughout early childhood seems to curb children’s brain power, according to a large, long term study.

A computational vision scientist at the University of South Australia has just published new research describing a key advance in our understanding of how the brain perceives the physical world.

Oxytocin has long been known as the warm, fuzzy hormone that promotes feelings of love, social bonding and well-being. It’s even being tested as an anti-anxiety drug. But new research shows oxytocin also can cause emotional pain, an entirely new, darker identity for the hormone.

Ultrasound waves sent to specific brain regions can alter a person’s mood, according to a new study published in the journal Brain Stimulation.

A gene related to neural tube defects in dogs has for the first time been identified by researchers.

UCLA chemists and molecular biologists have for the first time used a “structure-based” approach to drug design to identify compounds with the potential to delay or treat Alzheimer’s disease, and possibly Parkinson’s, Lou Gehrig’s disease and other degenerative disorders.

Scientists have shown that working as a piano tuner may lead to changes in the structure of the memory and navigation areas of the brain. The study, published in the Journal of Neuroscience, shows that these structural differences correlate with the number of years of experience a piano tuner has accumulated.

An unusual kind of circuit fine-tunes the brain’s control over movement and incoming sensory information, and without relying on conventional nerve pathways, according to a study published in the journal Neuron.

The reason we struggle to recall memories from our early childhood is down to high levels of neuron production during the first years of life, say Canadian researchers.

Researchers have identified mutations in several new genes that might be associated with the development of spontaneously occurring cases of the neurodegenerative disease known as amyotrophic lateral sclerosis, or ALS. Also known as Lou Gehrig’s disease, the progressive, fatal condition, in which the motor neurons that control movement and breathing gradually cease to function, has no cure.

The brains of people with depression show a reduced ability to adapt to their environment, a unique study shows.

Researchers at the Stanford University School of Medicine have found that a naturally occurring protein secreted only in discrete areas of the mammalian brain may act as a Valium-like brake on certain types of epileptic seizures.

Brain scan

The researchers monitored brain activity while playing volunteers new music

Listening to new music is rewarding for the brain, a study suggests. Using MRI scans, a Canadian team of scientists found that areas in the reward centre of the brain became active when people heard a song for the first time. The more the listener enjoyed what they were hearing, the stronger the connections were in the region of the brain called the nucleus accumbens. The study is published in the journal Science.

Meanwhile, an imaging study by Stanford University School of Medicine scientists reveals that the brains of different people listening to the same piece of music actually respond in the same way –  which may in part explain why music plays such a big role in our social existence.

Researchers have identified an important therapeutic target for alleviating the symptoms of Lou Gehrig’s disease, also known as amyotrophic lateral sclerosis (ALS), and other related neurodegenerative disorders such as Alzheimer’s disease, Parkinson’s disease and Huntington’s disease.

In a study published in the online version of Neurobiology of Disease, the team both confirmed the importance of this new target as well as a series of compounds that can be used to attenuate the dysregulation of one of the important cellular processes that lead to and ultimately to .

Neuroscientists have developed a method of analyzing brain activity to detect autism in children. Their findings appear in the online journal PLOS ONE.

Slow oscillations in brain activity, which occur during so-called slow-wave sleep, are critical for retaining memories. Researchers reporting online in the Cell Press journal Neuron have found that playing sounds synchronized to the rhythm of the slow brain oscillations of people who are sleeping enhances these oscillations and boosts their memory. This demonstrates an easy and noninvasive way to influence human brain activity to improve sleep and enhance memory.
