The next time you get really mad, take a look in the mirror. See the lowered brow, the thinned lips and the flared nostrils? That’s what social scientists call the “anger face,” and it appears to be part of our basic biology as humans.
Now, researchers at UC Santa Barbara and at Griffith University in Australia have identified the functional…[Read more]
Discovery may help treat memory disorders resulting from stroke, Alzheimer’s and brain injury.
Stimulating a particular region in the brain via non-invasive delivery of electrical current using magnetic pulses, called Transcranial Magnetic Stimulation, improves memory, reports a new Northwestern Medicine study.
The discovery opens a new…[Read more]
New imaging technique shows how cocaine shuts down blood flow in mouse brains.
A new method for measuring and imaging how quickly blood flows in the brain could help doctors and researchers better understand how drug abuse affects the brain, which may aid in improving brain-cancer surgery and tissue engineering, and lead to better treatment…[Read more]

“You may say I’m a dreamer, but I’m not the only one,” sang John Lennon in his 1971 song Imagine.
And thanks to the dreams of a BYU student, we now know more about where and how imagination happens in our brains.
Stefania Ashby and her faculty mentor devised experiments using MRI technology that would help them distinguish pure imagination…[Read more]

Extremely low levels of the compound in marijuana known as delta-9-tetrahydrocannabinol, or THC, may slow or halt the progression of Alzheimer’s disease, a recent study from neuroscientists at the University of South Florida shows.
Findings from the experiments, using a cellular model of Alzheimer’s disease, were reported online in the Journal…[Read more]
Gamblers show the same tendencies as pigeons when they make risky decisions, new research has shown.
Researchers, led by Dr Elliot Ludvig of the University of Warwick’s Department of Psychology, conducted tests that found that both human gamblers and pigeons were 35% more likely to gamble for high-value than low-value rewards.

Xenon exposure may be potential new treatment for people with PTSD.
Researchers at Harvard-affiliated McLean Hospital are reporting that xenon gas, used in humans for anesthesia and diagnostic imaging, has the potential to become a treatment for post-traumatic stress disorder (PTSD) and other memory-related disorders.
“In our study, we found…[Read more]
When we want to listen carefully to someone, the first thing we do is stop talking. The second thing we do is stop moving altogether. This strategy helps us hear better by preventing unwanted sounds generated by our own movements.
This interplay between movement and hearing also has a counterpart deep in the brain. Indeed, indirect evidence has…[Read more]
By manipulating neural circuits in the brain of mice, scientists have altered the emotional associations of specific memories. The research, led by Howard Hughes Medical Institute investigator Susumu Tonegawa at the Massachusetts Institute of Technology (MIT), reveals that the connections between the part of the brain that stores contextual…[Read more]

Findings, published in Nature, could lead to improved treatments for stroke, other brain injuries.
Learning a new skill is easier when it is related to an ability we already have. For example, a trained pianist can learn a new melody easier than learning how to hit a tennis serve.
Neural engineers from the Center for the Neural Basis of…[Read more]

MK2/3 cascade plays a role in synaptic plasticity and cognition.
Scientists at the University of Warwick have provided the first evidence that the lack of a naturally occurring protein is linked to early signs of dementia.
Published in Nature Communications, the research found that the absence of the protein MK2/3 promotes structural and…[Read more]
Previously reported autism risk appears to be attributable to mother’s illness, not medication.
Previous studies that have suggested an increased risk of autism among children of women who took antidepressants during pregnancy may actually reflect the known increased risk associated with severe maternal depression. In a study receiving advance…[Read more]

A balance board accessory for a popular video game console can help people with multiple sclerosis (MS) reduce their risk of accidental falls, according to new research published online in the journal Radiology. Magnetic resonance imaging (MRI) scans showed that use of the Nintendo Wii Balance Board system appears to induce favorable changes in…[Read more]
When an animal encounters a new environment, the neurons in its brain that are responsible for mapping out the space are ready for anything. So says a new study in which scientists at the Howard Hughes Medical Institute’s Janelia Research Campus examined neuronal activity in rats as they explored an unusually large maze for the first time.
Cells have receptors on their surface that serve as gatekeepers to transmit signals between the outside and inside. Nerve cells contain glutamate receptors that span the cell membrane. When glutamate binds the receptor on the outside, the receptor changes shape and opens within milliseconds. This allows small substances known as ions to enter the…[Read more]
A study is shining new light on a sleep disorder called “sleep drunkenness.” The disorder may be as prevalent as affecting one in every seven people. The research is published in the August 26, 2014, print issue of Neurology, the medical journal of the American Academy of Neurology.
Sleep drunkenness disorder involves confusion or inappropriate…[Read more]

Researchers at the University of California, San Diego School of Medicine have found one of the keys to why certain glioblastomas – the primary form of a deadly brain cancer – are resistant to drug therapy. The answer lies not in the DNA sequence of the tumor, but in its epigenetic signature. These findings have been published online as a priority…[Read more]
