Human stem cell treatment restores motor function in paralyzed rats

...al cord trauma, such as might occur in a diving or car accident, is that in the ischemia model, no mechanical damage has occurred to the spinal cord,” said Marsala. “The spinal cord and brain motor centers are still partially connected, but there has been a selective loss of inhibitory neurons in the sp...

Using brain scans, researchers find evidence for a two-stage model of human perceptual learning

...aining had enhanced the brain's ability to process car shapes. They found again that cars selectively act... in that area appeared to be finely tuned to small car shape differences. In a third scan, the investigators finally asked subjects to categorize the s...

Proteins important in Alzheimer's, Parkinson's disease travel in the slow lane

... when they’re going to the same place anyway, like car pooling" speculates Roy. "Our study reveals novel aspects of axonal transport of an important class of proteins, namely the slow component-b proteins, and also opens up new avenues for investigating axonal transport defects in neurodegenerative d...

New research shows why too much memory may be a bad thing

...ormation for a limited timeframe, e.g., where your car is parked in a huge mall lot or remembering a phone number for few seconds before writing it down. Because working memory is highly sensitive to interference from information previously stored in memory, forgetting such information may therefore be n...

Learning during sleep?

If I can't remember this morning where I put my car keys last night, it's due to my memory failing me again. Scientists at the Max Planck Institute for Medical Research in Heidelberg have been investigating how memories might be consolidated. Their new study offers the hitherto strongest proof that ne...

Memories: It's all in the packaging, scientists say

...eople only recall parts of an experience such as a car accident, and yet vividly recall all of the details of a similar experience. In experiments using functional magnetic resonance imaging (fMRI), the scientists were able to view what happened in the brains of subjects when they experienced an event...

Hopkins researchers discover how brain protein might control memory

... mean for our ability to remember where we put the car keys? "We know that animals lacking Arc live only in the here and now. They learn fine in the short term, but tomorrow they will need to relearn everything," says Worley. And in the case of long-term memories that are better forgotten, such as that c...

First biomarker for human sleepiness identified in fruit flies

...ssess the risk of falling asleep at the wheel of a car or in other dangerous contexts. "As we prepare for the holiday season and long drives to distant relative's houses, I hope this finding will get people thinking about the dangers and costs of sleep deprivation," says lead author Paul J. Shaw, Ph.D...

Altered perception of reward in human cocaine addiction

...isadvantageous decisions -- for example, trading a car for a couple of cocaine hits. Without a relative context, drug use and its intense effects -- craving, anticipation, and high -- could become all the more overpowering," she said. The behavioral data collected during fMRI further suggested that, i...

PNAS study reveals why organs fail following massive trauma

...s more likely to survive severe injury caused by a car crash, gunshot or fall thanks to high-tech emergency medicine. Unfortunately, the body does not know what to do when it survives an injury that would have been fatal until recently in human evolution. Nearly one third of the time, mechanisms in place...

How brain injury leads to seizures, memory problems

...TBI patients." Transportation accidents such as car crashes are responsible for the majority of TBIs in people under age 75. According to the National Institutes of Health, over 5 million Americans currently have permanent disabilities resulting from TBIs. The study, which was done in animals, appe...

Gene chip technology shows potential for identifying life-threatening blood infection

...ering from surgery, pancreatitis, or trauma from a car accident or fall. Because these patients are also hooked up to IV fluids, catheters or ventilators, they are also prone to bacterial infections, including pneumonia, that can quickly spiral out of control and lead to sepsis. Although both conditio...

Emotional control circuit of brain's fear response discovered

...action is needed or not. For example, if it was a car door slamming, the rACC would shut down the amygdala." "Based on these findings, tailored treatments may someday be developed based on the biology of the person's disease," said Eric Kandel, M.D., Howard Hughes Medical Institute senior investigator...

UCSD researchers develop 'smart petri dish'

...xin, they scatter light better, much like fog on a car windshield, allowing us to quickly detect which drugs may have adverse side effects when taken in combination with another," says Sailor. "You're not supposed to drink alcohol when taking acetaminophen, because the combination of the two is much more...

Key to early diagnosis of autism may be in the placenta

They will examine the placentas of the children in the study in greater detail to gain insight into the biological basis...

A more powerful and efficient engine for rice: the C3-C4 challenge

... whole plant benefits." "If we continue with the car analogy, the Green Revolution of the 1960s and 1970s, which resulted in high-yielding semidwarf rice varieties, focused on providing a new, more compact body for the rice plant," Dr. Sheehy added. "But we have never really got under the hood and trie...

Tiny shock absorbers help bacteria stick around inside the body

...tem is similar to a set of shock absorbers on your car that dampen turbulent forces caused by bumpy road conditions," added study co-author Dr. Wendy Thomas, assistant professor of bioengineering at the UW. The researchers found that fimbrial uncoiling and recoiling events balance each other at an inte...

Researches discover gene critical for protection against septic-shock-induced death

...ne of defense. "Sepsis syndrome is like a speeding car with a brake failure. Nrf2 may function like a brake that regulates the speed," said Biswal, senior author of the study and assistant professor in the Bloomberg School's Department of Environmental Health Sciences. Biswal speculates that suboptimal f...
