Deflecting Damage: Flexible Electronics Aid Brain Injury Research

... comas to epilepsy. These improperly functioning neurons can now be assessed by the electrodes in the stretchable membranes. After brain cells have been placed on the flexible surface and allowed to grow, the researchers measure their normal activity. The membrane is then suddenly stretched and returned to...

Research Explains How Lead Exposure Produces Learning Deficits

...ated children reduce the birth and survival of new neurons (neurogenesis) in the brain. Lead also alters the normal development of newly born neurons in a part of the brain (hippocampus) known to be important for learning and memory. “There was a...

Research to Protect Accident Victims from Epilepsy

...lasticity -- misfiring circuitry can form. Injured neurons can make new connections in wrong places, or overly excitable connections. Even the brain's genes change the way they work after head injury. "You need the plasticity for recovery. You don't want to stop it. You just want to structure it in a way t...

Exposure to a Soil Bacterium can Boost Happiness

...ressant properties through activation of serotonin neurons - a chemical in the brain that helps maintain a 'happy feeling', and seems to help keep our moods under control by helping with sleep, calming anxiety and relieving depression. Mice exposed to the bacteria made more of the brain's "happy" chemical ...

It's Never too Late to Get It Back! Aging Interrupted

...ous, and to stimulate repair in damaged cells like neurons and heart cells. Low calorie diets drive the body to replace and repair damaged cells. This process usually slows down as we age, but low calorie diets make the body re-synthesise and turn over more cells – a situation associated with youth and good ...

Be Happy- Get On Your Knees And Play In The Mud

...mulated the immune system and activated a group of neurons in the brain, which produce the mood enhancing chemical serotonin. Says Lowry, who published the report in the journal Neuroscience: "These studies help us understand how the body communicates with the brain and why a healthy immune system is impor...

MEG Scanners Are Mega Powerful

..., the MEG scanners track the magnetic signals that neurons throw off as they communicate. "You can look at how the networks of the brain are talking to each other in real time," said Greg Simpson, director of the Dynamic Neuroimaging Laboratory at the University of California at San Francisco. The machines a...

Brain Tissue Reveals Possible Genetic Trigger for Schizophrenia

...portantly in “synaptic plasticity,” the ability of neurons to make connections with one another. “And those connections between neurons come and go all the time. It’s a normal process for them to be pruned and grow again, depending on w...

New Reason to Hit the Gym: Fighting Memory Loss

...ntate gyrus is the one area of the brain where new neurons are generated, and that exercise improves this process. This is the first human study to emerge out of this observation. “Our next step is to identify the exercise regimen that is most beneficial to improve cognition and reduce normal memory loss, ...

"We really appreciate the patients who made the commitment to participate in this two-year-long study while they were in their ...

Nanoparticle Research Offers Hope of Artificial Retinas, Prostheses

...riendly coating of amino acid, and placed cultured neurons on the very top. When light shines on them, the mercury-tellurium nanoparticle film layers produce electrons, which then move up into the PDDA film layers and produce an upward-moving electrical current. "As you build up the layers of this, you get...

Mouse Study Suggests Anxiety Disorders Take Root in Infancy

...He proposes that variations in serotonin-sensitive neurons and serotonin receptors early in life might account for the importance of maternal nurturing in preventing emotional disorders later in life. Rats that were not groomed sufficiently as pups by their mothers display elevated levels of anxiety as adult...

Treatment Extends Survival in Mouse Model of Spinal Muscular Atrophy

...n showed that the TSA-treated mice also had larger neurons in the spinal cord, thicker muscle fibers, and more muscle mass than untreated mice. "This is a proof-of-concept experiment," says Dr. Sumner. "It clearly demonstrates that this treatment can ameliorate the disease in mice." While the results are ...
