For many patients with advanced Parkinson’s disease, deep brain stimulation can mean the difference between having difficulty walking and being able to run. Since its approval by the Food and Drug Administration in 1997, the treatment has been used by 20,000 patients with advanced Parkinson’s disease or other movement disorders to help control their symptoms. Now, researchers have discovered that surgically implanting electrical stimulators on just one side of a patient’s brain could help alleviate symptoms on both sides of the body, potentially cutting the surgery risk for some patients. The results are published in the October issue of the journal Motor Control.
There are currently two sites in each hemisphere of the brain where stimulation is targeted. In the same study, researchers found no significant difference in motor performance between two groups of patients who received stimulation at either site. But given past evidence that patients who receive stimulation at one of the sites may be more prone to depression and other neuropsychological conditions, the study’s authors conclude the current bias toward placing the implants on that site may be unwarranted.
"These data clearly indicate that unilateral deep brain stimulation improves bilateral motor performance of the arms and hands,” said Jay Alberts, an assistant professor in the School of Applied Physiology at the Georgia Institute of Technology.

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
