A new way to artificially control muscles using light, with the potential to restore function to muscles paralyzed by conditions such as motor neuron disease and spinal cord injury, has been developed by scientists at UCL and King’s College London. The technique involves transplanting specially-designed motor neurons created from stem cells into injured nerve branches. These motor neurons are designed to react to pulses of blue light, allowing scientists to fine-tune muscle control by...

By studying nerve cells that originated in patients with a severe neurological disease, a University of Wisconsin-Madison researcher has pinpointed an error in protein formation that could be the root of amyotrophic lateral sclerosis. Also called Lou Gehrig's disease, ALS causes paralysis and death. According to the ALS Association, as many as 30,000 Americans are living with ALS. After a genetic mutation was discovered in a small group of ALS patients, scientists transferred that gene...

For Simon Gilroy, sometimes seeing is believing. In this case, it was seeing the wave of calcium sweep root-to-shoot in the plants the University of Wisconsin-Madison professor of botany is studying that made him a believer. Gilroy and colleagues, in a March 24, 2014 paper in the Proceedings of the National Academy of Sciences, showed what long had been suspected but long had eluded scientists: that calcium is involved in rapid plant cell communication. It's a finding that has...

Researchers report they can generate human motor neurons from stem cells much more quickly and efficiently than previous methods allowed. The finding, described in Nature Communications, will aid efforts to model human motor neuron development, and to understand and treat spinal cord injuries and motor neuron diseases such as amyotrophic lateral sclerosis (ALS). The new method involves adding critical signaling molecules to precursor cells a few days earlier than previous methods...

KIT computer models explain how ion channels in cell membranes react to light / light switch for nerve cells as a sensitive tool of research Networked nerve cells are the control center of organisms. In a nematode, 300 nerve cells are sufficient to initiate complex behavior. To understand the properties of the networks, re-searchers switch cells on and off with light and observe the resulting behavior of the organism. In the Science journal, sci-entists now present a protein that...

A new discovery suggests it could one day be possible to chemically reprogram and repair damaged nerves after spinal cord injury or brain trauma. Researchers from Imperial College London and the Hertie Institute, University of Tuebingen have identified a possible mechanism for re-growing damaged nerve fibres in the central nervous system (CNS). This damage is currently irreparable, often leaving those who suffer spinal cord injury, stroke or brain trauma with serious impairments like loss...

UCLA study discovers potassium boost improves walking in mouse model Tweaking a specific cell type's ability to absorb potassium in the brain improved walking and prolonged survival in a mouse model of Huntington's disease, reports a UCLA study published March 30 in the online edition of Nature Neuroscience. The discovery could point to new drug targets for treating the devastating disease, which strikes one in every 20,000 Americans. Huntington's disease is passed from parent to child...

Memories are difficult to produce, often fragile, and dependent on any number of factors—including changes to various types of nerves. In the common fruit fly—a scientific doppelganger used to study human memory formation—these changes take place in multiple parts of the insect brain. Scientists from the Florida campus of The Scripps Research Institute (TSRI) have been able to pinpoint a handful of neurons where certain types of memory formation occur, a mapping feat that one day...

The problems people with autism have with memory formation, higher-level thinking and social interactions may be partially attributable to the activity of receptors inside brain cells, researchers at Washington University School of Medicine in St. Louis have learned. Scientists were already aware that the type of receptor in question was a potential contributor to these problems – when located on the surfaces of brain cells. Until now, though, the role of the same type of receptor...

[ Watch the Video: First Stem Cell Study of Bipolar Disorder Yields Promising Results ] April Flowers for redOrbit.com - Your Universe Online Bipolar disorder affects 200 million people globally, and yet there are so many questions surrounding the condition. Why are individuals with bipolar disorder prone to manic highs and deep, depressed lows? If there is no single gene to blame, why does bipolar disorder run so strongly in families? And why, with the enormous number of people...

Formation and Orientation The development of the brain is broken down into stages. The basic evolution begins in the third week of the embryonic process where the neural plate is formed. By week four, the neural plate has developed into the neural tube. The anterior part of the tube, the telencephalon, grows rapidly as it prepares to later give way to the brain. As time goes on, cells begin to classify themselves as either neurons or glial cells, thus determining their functions. Glial...
