A possible explanation for why male mice tolerate stress better than females

Posted by in categories: biotech/medical, neuroscience

The nerves we feel before a stressful event—like speaking in public, for example—are normally kept in check by a complex system of circuits in our brain. Now, scientists at Rockefeller University have identified a key molecule within this circuitry that is responsible for relieving anxiety. Intriguingly, it doesn’t appear to reduce anxiety in female mice, only in males.

“This is unusual, because the particular cell type involved here is the same in the male and female brain—same in number, same in appearance,” says Nathaniel Heintz, head of the Laboratory of Molecular Biology and a Howard Hughes Medical Institute investigator. “It’s a rare case where a single cell type is activated by the same stimulus but yields two different behaviors in each gender.”

New science revelations: Trees communicate with each other and have social circles

Posted by in categories: neuroscience, science

Friday, October 14, 2016 by: Ethan A. Huff, staff writerTags: trees, social communication, plant science (NaturalNews) If trees could talk, what would they say? Emerging research suggests that if they had mouths, they might just say a whole lot because, believe it or not, trees have brains and intelligence, and are able to communicate with other trees much like humans do with other humans when in social situations.

Engineering a Better Body and the End of Disease

Posted by in categories: biotech/medical, computing, engineering, health, mobile phones, neuroscience, policy

There are two kinds of people in Washington, DC, says entrepreneur Dean Kamen. There are the policy experts, whom he calls cynics. And there are the scientists, whom he deems optimists.

Kamen, speaking at the White House Frontiers Conference at the University of Pittsburgh, places himself in the latter camp. Unlike policy wonks and politicians who see diseases like Alzheimer’s or ALS as unstoppable scourges, Kamen points out that previously terrifying diseases were all toppled by medical innovation. The plague, polio, smallpox — all were civilization-threatening epidemics until experimental scientists discovered new ways to combat them.

If that sounds like the kind of disruption that the tech industry has unleashed across the rest of the world, that’s no accident. Kamen, the founder of DEKA, a medical R&D company, says that the same trends that have empowered our computers and phones and communication networks will soon power a revolution in health care. He says that medical innovation follows a predictable cycle. First we feel powerless before a disease. Then we seek ways of treating it. Then we attempt to cure it.

This Revolutionary Bionic Eye Sends Images Directly To Your Brain

Posted by in categories: cyborgs, neuroscience, transhumanism

In Brief:

This newly developed bionic eye sends images directly to the brain to restore a tiny fraction of the pixels a normal eye can produce.

There are about 285 million people in the world who suffer from some type of visual impairment. For many years, researchers have been looking for ways to restore eyesight. This year, Australian volunteers are set to receive bionic eyes which should help restore their vision.

The future of brain and machine is intertwined, and it’s already here

Posted by in categories: futurism, neuroscience

Imagine a condition that leaves you fully conscious, but unable to move or communicate, as some victims of severe strokes or other neurological damage experience.

This is locked-in syndrome, when the outward connections from the brain to the rest of the world are severed. Technology is beginning to promise ways of remaking these connections, but is it our ingenuity or the brain’s that is making it happen?

Brain modulyzer provides interactive window into the brain

Posted by in categories: biotech/medical, computing, neuroscience

For the first time, a new tool developed at the Department of Energy’s (DOE’s) Lawrence Berkeley National Laboratory (Berkeley Lab) allows researchers to interactively explore the hierarchical processes that happen in the brain when it is resting or performing tasks. Scientists also hope that the tool can shed some light on how neurological diseases like Alzheimer’s spread throughout the brain.

Created in conjunction with computer scientists at University of California, Davis (UC Davis) and with input from neuroscientists at UC San Francisco (UCSF), the software, called Brain Modulyzer, combines multiple coordinated views of functional magnetic resonance imaging (fMRI) data — like heat maps, node link diagrams and anatomical views — to provide context for brain connectivity data.

“The tool provides a novel framework of visualization and new interaction techniques that explore the brain connectivity at various hierarchical levels. This method allows researchers to explore multipart observations that have not been looked at before,” says Sugeerth Murugesan, who co-led the development of Brain Modulyzer. He is currently a graduate student researcher at Berkeley Lab and a PhD candidate at UC Davis.

Nightingale Sleep encourages slumber under a white noise “sound blanket”

Posted by in categories: internet, media & arts, neuroscience

Pitch black darkness and silence may help some people drift off at night, but others fall asleep better with music, TV or a fan on in the room. For the latter group, a white noise machine or app can be a handy bedside companion, but Cambridge Sound Management claims it has a better option with the Nightingale, a new Internet of Things-enabled system that uses two speakers in a room to create a “sound blanket” that is designed to blend into the background and block disruptive sounds.

Devices like the Snooz are designed to sit by the bed while they give off their comforting soundscapes, but according to CSM, when sound is coming from a single source a listener’s brain can pinpoint it, making it less effective at helping people switch off and drift off. To counter this apparent shortcoming, the Nightingale system comes in pairs, and placing them in different parts of the room creates a more uniform blanket of white noise that the brain can’t precisely locate.

Each unit contains two speakers, and when plugged into an outlet – actually two outlets –, outputs ambience from a selection of 15 different types of soundscapes. The company says the layout of the room is taken into account, and the devices will work even when plugged in behind furniture. Electrical outlet real estate is valuable, so the front of each unit contains two more outlets, to replace the ones it’s hogging.
