Neurophysiology News and Research

Neurophysiology is a discipline within the health sciences which deals with the measurement and assessment of nervous system function rather than the anatomy of the nervous system. It helps to diagnose and monitor the progress of nervous disorders.

Medical devices for diabetic peripheral neuropathy: an interview with Dr. Shai Gozani, CEO of NeuroMetrix

About two years ago NeuroMetrix changed their focus from general purpose devices, used to perform nerve conduction tests, to devices designed to specifically address diabetic peripheral neuropathy or DPN.

Novel technique can restore hand function in patients with spinal cord injury

Justin M. Brown, MD, reconstructive neurosurgeon at UC San Diego Health System, is one of only a few specialists in the world who have pioneered a novel technique to restore hand function in patients with spinal cord injury. In a delicate four-hour procedure, Brown splices together tiny nerve endings, only one millimeter in width, to help restore hand mobility. Most patients return home 24 hours after surgery.

Non-invasive stimulation of cerebellum helps individuals learn new walking patterns

In a step towards improving rehabilitation for patients with walking impairments, researchers from the Kennedy Krieger Institute found that non-invasive stimulation of the cerebellum, an area of the brain known to be essential in adaptive learning, helped healthy individuals learn a new walking pattern more rapidly.

Paper explores links between neuronal avalanches and spike time-dependent plasticity

The brain's neurons are coupled together into vast and complex networks called circuits. Yet despite their complexity, these circuits are capable of displaying striking examples of collective behavior such as the phenomenon known as "neuronal avalanches," brief bursts of activity in a group of interconnected neurons that set off a cascade of increasing excitation.

Toxic plants and animal products found in traditional Chinese medicines

A study has found that some traditional Chinese medicines contain potentially poisonous plants, unlabelled ingredients and bits of endangered animals. This has triggered a bid for routine testing and tighter regulation of complementary medicines.

Towards a more comprehensive view of brain-hand relationship

Research at Arizona State University and Columbia University to better understand the intricate sensory and cognitive connections between the brain and the hands has won support from the National Science Foundation. New discoveries about such connections could benefit people with neurological disorders such as Parkinson's disease and cerebral palsy, and those who need prosthetic hands.

AADR honors University of Maryland scientist for pain research

Ronald Dubner, PhD, DDS, of the University of Maryland School of Dentistry was honored today with the 2012 Distinguished Scientist Award by the American Association for Dental Research.

The two sides of pain

"Pain is both a curse and a blessing", says Jürgen Sandkühler, Head of the Department of Neurophysiology at the Centre for Brain Research at the MedUni Vienna ahead of the international "Brain Awareness Week", being held from the 12th to the 16th of March. On the one hand, pain has an important protective function for humans.

Yoga may be effective in treating patients with stress-related psychological and medical conditions

An article by researchers from Boston University School of Medicine (BUSM), New York Medical College (NYMC), and the Columbia College of Physicians and Surgeons (CCPS) reviews evidence that yoga may be effective in treating patients with stress-related psychological and medical conditions such as depression, anxiety, high blood pressure and cardiac disease.

Physiological problems stemming from concussions may persist

A study recently published by the University of Kentucky's Scott Livingston shows that physiological problems stemming from a concussion may continue to present in the patient even after standard symptoms subside.

Intraoperative monitoring of spinal cord may help prevent paralysis

The American Academy of Neurology is issuing an updated guideline that recommends monitoring the spinal cord during spinal surgery and certain chest surgeries to help prevent paralysis, or loss of muscle function, related to the surgeries.

Finnish researchers break ground in neonatal brain research

In the past few years, researchers at the University of Helsinki have made several breakthroughs in discovering how the brain of preterm babies work, in developing treatments to protect the brain, and in developing research methods suitable for hospital use.

Visual working memory not as specialized in the brain as visual encoding

Researchers have long known that specific parts of the brain activate when people view particular images. For example, a region called the fusiform face area turns on when the eyes glance at faces, and another region called the parahippocampal place area does the same when a person looks at scenes or buildings. However, it's been unknown whether such specialization also exists for visual working memory, a category of memory that allows the brain to temporarily store and manipulate visual information for immediate tasks.

Scientists reveal novel mechanism underpinning age-dependent changes to cognitive abilities

New findings, led by neuroscientists at the University of Bristol and published this week in the journal Neurobiology of Aging, reveal a novel mechanism through which the brain may become more reluctant to function as we grow older.

Researchers discover previously unknown effect of opioids

A team of researchers at the MedUni Vienna's Department of Neurophysiology has discovered a previously unknown effect of opioids: the study, which has now been published in the highly respected magazine "Science" and was led by Ruth Drdla-Schutting and Jürgen Sandkühler, shows that opioids not only temporarily relieve pain, but at the right dose can also erase memory traces of pain in the spinal cord and therefore eliminate a key cause of chronic pain.

Researchers study fusion plasmas to understand fast dynamics of networks in the human brain

Fusion plasma researchers at the University of Warwick have teamed up with Cambridge neuroscientists to apply their expertise developed to study inaccessible fusion plasmas in order to significantly improve the understanding of the data obtained from non-invasive study of the fast dynamics of networks in the human brain.

Researchers discover that humans are natural-born multi-taskers

Imagine you're a hockey goalie, and two opposing players are breaking in alone on you, passing the puck back and forth. You're aware of the linesman skating in on your left, but pay him no mind. Your focus is on the puck and the two approaching players. As the action unfolds, how is your brain processing this intense moment of "multi-tasking"? Are you splitting your focus of attention into multiple "spotlights?" Are you using one "spotlight" and switching between objects very quickly? Or are you "zooming out" the spotlight and taking it all in at once?

Testing athletes for concussions may induce mental fatigue

Testing athletes for concussions may induce mental fatigue in subjects whether or not they have a head injury, according to Penn State researchers.

New review article: Pitch center does not exist in auditory cortex

The perceptual feature of sound known as pitch is fundamental to human hearing, allowing us to enjoy the melodies and harmonies of music and recognize the inflection of speech. Previous studies have suggested that a particular hotspot in the brain might be responsible for perceiving pitch. However, auditory neuroscientists are still hotly debating whether this "pitch center" actually exists.

Neurorehabilitation journal reviews clinical advances in treatment of vestibular problems

Over the last 25 years, intensive efforts by physicians, physical therapists, and occupational therapists have developed integrative rehabilitation regimens that can alleviate balance disorders associated with neurological disease, trauma or weightlessness.
