Flow through pain-sensing molecule helps worms adapt to pain.
When you accidentally touch a hot oven, you rapidly pull your hand away. Although scientists know the basic neural circuits involved in sensing and responding to such painful stimuli, they are still sorting out the molecular players.
Duke researchers have made a surprising…[Read more]
Average person usually averse to lying, researchers say.
What’s the price of your integrity? Tell the truth; everyone has a tipping point. We all want to be honest, but at some point, we’ll lie if the benefit is great enough. Now, scientists have confirmed the area of the brain in which we make that decision.
The result was published online…[Read more]
Neuroscience News wrote a new post, Discovery Hints at Why Stress Is More Devastating for Some, on the site Neuroscience News 1 hour, 48 minutes ago
Some people take stress in stride; others are done in by it. New research at Rockefeller University has identified the molecular mechanisms of this so-called stress gap in mice with very similar genetic backgrounds — a finding that could lead researchers to better understand the development of psychiatric disorders such as anxiety and…[Read more]
Neuroscience News wrote a new post, A Nucleotide Change Could Initiate Fragile X Syndrome, on the site Neuroscience News 1 day, 2 hours ago
Researchers reveal how the alteration of a single nucleotide, the basic building block of DNA, could initiate fragile X syndrome, the most common inherited form of intellectual disability. The study appears in The Journal of Cell Biology.
Fragile X syndrome is caused by a defect in a gene on the X chromosome called fragile X mental retardation…[Read more]
New York University biologists have identified a mechanism that helps explain how the diversity of neurons that make up the visual system is generated.
“Our research uncovers a process that dictates both timing and cell survival in order to engender the heterogeneity of neurons used for vision,” explains NYU Biology Professor Claude Desplan,…[Read more]

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]

First MS study to use functional near infrared spectroscopy to examine brain activation during working memory task.
Using functional near infrared spectroscopy (fNIRS), Kessler Foundation researchers have shown differential brain activation patterns between people with multiple sclerosis (MS) and healthy controls. This is the first MS study in…[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.

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.
