Laura Wong has coaxed damaged nerve cells to grow and send messages to the brain again Unlike tissues such as skin and bone, the cells of the central nervous system in an adult are notoriously resistant to healing. PrintEmail“An ailment not to be treated,” read the prescription for a spinal cord injury on an Egyptian papyrus in 1,700 B.C.
Her findings, which she presented at the annual meeting of the Society for Neuroscience in 2011 and 2012, shed light on the complex processes behind nerve cell growth and regeneration.
Researchers in Frank’s lab have been seeking ways to either stimulate growth or block the mechanisms that inhibit nerve cell growth—or both—since 2005. The damage mimics a common injury called Erb’s palsy, which can occur when a baby’s shoulder gets caught behind the mother’s pelvis during labor and delivery, creating undue strain on nerves in the newborn’s neck. In earlier experiments, Harvey and Frank found that treating with artemin did indeed stimulate the sensory nerve fibers to regenerate and grow back into the spinal cord over the course of about six weeks. That’s important, because while axons only have to grow across microscopic distances in a developing embryo, they would have to bridge much wider gaps—depending on the site of the injury—to heal a neural injury in an adult, Wong says.
That’s crucial because should the sensory nerves that relay pain signals become crossed, for example, it could result in a patient feeling phantom pain or the sensation of pain from something that shouldn’t cause discomfort at all. But if the findings, which Wong presented at the Society for Neuroscience meetings in 2011 and 2012, prove applicable to humans, restoring sensation alone could still improve quality of life, even for those living with paralysis. Wong hopes her work with sensory neurons will help unlock the secrets to promoting regeneration of other, more obstinate types of neurons in the brainstem and spinal cord.
Chris Nowinski, another former WWE superstar known as Chris Harvard during his days in the squared circle, is one of the forefathers of brain trauma awareness in the NFL.Nash told ESPN that he's made the decision to donate his brain and spine to Chris Nowinski's Concussion Legacy Foundation and Boston University's CTE Center. The cerebrum , otherwise known as the telencephalon, makes up about 80 percent of the brain's weight.

You’re still not going to get any function,” says Wong, who has worked since 2010 in Frank’s lab, which is trying to develop therapies for spinal cord injuries. If those results can be replicated in patients, it could prevent certain types of nerve damage and improve quality of life for some. Not only does the supply of natural growth stimulants decline as we age, but the body also produces chemicals that discourage nerve cells from regenerating.
Wong’s predecessor in the lab, Pamela Harvey, a 2009 graduate of the Sackler School, tested a synthetic version of a nerve cell growth factor, called artemin, on crushed sensory neurons that relay information from the hands, arms and shoulders to the brain.

In her follow-up experiments, Wong showed that artemin could induce those nerve fibers to grow the 3- to 4-centimeter distance from there up to the brainstem, where the brain and the spinal cord meet. Nerves that extend from the spine to the foot or toe can reach lengths of about 60 centimeters, she adds.
They also reestablished connections with correct regions in the brain stem, just as Harvey had seen the nerve cells do in the spinal cord. To work its cellular magic, the compound must be administered within a day or two, and the sooner the better. Giving these people the ability to sense heat, cold and pain could help them avoid other accidental injuries, says Frank. While she demonstrated that the sensory nerves plugged themselves back into the spinal cord precisely where they should have, it’s not clear how they did that.
Should researchers be able to identify those cues, they potentially could use that knowledge to spark regeneration of other classes of neurons, such as motor neurons. He said he suffers from short-term memory loss and has been more emotional in recent years, though he couldn't say that it's definitely related to brain trauma.Professional wrestler Kevin Nash and soccer legend Brandi Chastain have openly stated that they will offer their brains, respectively, as gifts for Science research on Chronic Traumatic Encephalopathy or CTE.
Despite decades of research, modern medicine has made little headway in its quest to reverse damage to the central nervous system. Worse, the scar tissue that starts to form immediately after a spinal cord injury also contains compounds that hinder nerve cell growth. That’s a little more than an inch—or roughly 10 times longer than any other researchers have been able to demonstrate with artemin or any other growth factor.
That is, the axons essentially plugged themselves back in just as they were prior to the injury, and, like an old-fashioned telephone switchboard, they sent the right messages to the right parts of the brain. Also, artemin promotes growth only in sensory neurons—and so far, only in rats—which means such growth wouldn’t improve motor function for someone who had been paralyzed by a spinal cord injury, for example.
The thalamus is an important relay station for sensory information coming to the cerebral cortex from other parts of the brain.
The middle peduncles transmit information from the cerebral cortex about the desired position of these body parts (Shier 2007). What’s more, the new neurons make organized connections with their counterparts inside the spinal cord and brain stem, ensuring information from the outside world paints an accurate picture inside the brain.
The thalamus also interprets sensations of pain, pressure, temperature, and touch, and is concerned with some of our emotions and memory.

The rabies virus spreads through the nerves of the brain and spinal cord first causing flu-like symptoms such as fever and malaise.
Anything you do in sports, go ice skate and fall and bang your head.At some point, the research needs to take another step forward, either by studying the brains of athletes who haven't experienced any of the symptoms associated with CTE, or by developing a way to test for the disease in living patients. As the disease advances it causes anxiety, confusion, brain dysfunction, progressing to hallucinations, delirium, and insomnia. More specifically, the brain lies within the cranial cavity of the skull, whereas the spinal cord occupies the vertebral canal within the vertebral column. Since he has retired he has become a prominent actor, including roles in the movies "Magic Mike" and "John Wick".
The folds are called convolutions or gyri, and the shallow grooves between the folds are sulci.
The hypothalamus controls normal body temperature and helps regulate the endocrine system, which produces hormones or chemical messengers that regulate body functions. It also contains centers that coordinate muscular movements, as well as centers and nerve pathways that regulate visceral activities.
It receives all sensory impulses (except those associated with the sense of smell) and channels them to appropriate regions of the cortex for interpretation. The corpus callosum, a bundle of more than 200 million neurons, connects the two cerebral hemispheres and carries vast amounts of information between them--an estimated 4 billion nerve impulses per second.
By studying patients whose corpora callosa had been destroyed, scientists have learned that some differences exist between the left and right hemispheres. Following the path of the spinal cord into the skull, the cord transitions into the brain via the medulla oblongata, ending in the lower section of the middle brain.
Just above and a few centimeters forward, rests the pituitary gland on a horizontal axis with the eyes and ears. Without this arousal, the cortex remains unaware of stimulation and cannot interpret sensory information or carry on thought processes. The right side of the brain, on the other hand, is more concerned with imagination, art, symbols, and spatial relations.
