Investigation by researchers from the University of Exeter and ETH Zurich has shed new light on a protein which is linked to a common neurological disorder called Charcot-Marie-Tooth disease.
The team has discovered that a protein previously identified on mitochondria – the energy factories of the cell – is also found on the fat-metabolising organelles peroxisomes, suggesting a closer link between the two organelles. (more…)
EAST LANSING, Mich. — Health professionals may soon have a new method of diagnosing Parkinson’s disease, one that is noninvasive and inexpensive, and, in early testing, has proved to be effective more than 90 percent of the time.
In addition, this new method has the potential to track the progression of Parkinson’s, as well as measure the effectiveness of treatments for the disorder, said Rahul Shrivastav, professor and chairperson of Michigan State University’s Department of Communicative Sciences and Disorders and a member of the team developing the new method.
It involves monitoring a patient’s speech patterns – specifically, movement patterns of the tongue and jaw. (more…)
In an effort to identify the underlying causes of neurological disorders that impair motor functions such as walking and breathing, UCLA researchers have developed a novel system to measure communication between stem cell–derived motor neurons and muscle cells in a Petri dish.
The study provides an important proof of principle that functional motor circuits can be created outside the body using these neurons and cells and that the level of communication, or synaptic activity, between them can be accurately measured by stimulating the motor neurons with an electrode and then tracking the transfer of electrical activity into the muscle cells to which the neurons are connected.

COLLEGE PARK, Md. — A team of neuroscientists has discovered important new information in the search for an effective 
treatment for Alzheimer’s disease, the debilitating neurological disorder that afflicts more than 5.3 million Americans and is the sixth-leading cause of death in the United States. Hey-Kyoung Lee , associate professor in the University of Maryland Department of Biology, and her research team have shown that they may be able to eliminate debilitating side effects caused by a promising Alzheimer’s drug by stimulating the brain’s nicotine receptors.
