Researchers at the Salk Institute for Biological Studies have identified an important circuit in the spinal cord that controls the speed with which our leg muscles contract and relax. Their findings mark an important milestone in understanding the neural circuitry that coordinates walking movements - one of the main obstacles in developing new treatments for spinal cord injuries.
"Knowing which circuits are important and understanding how they control the essential aspects of walking should put us in a better position to design treatments or implants that restore or activate these pathways," said Martyn D. Goulding, Ph.D., a professor in the Molecular Neurobiology Laboratory.
The Salk research team – led by Goulding– published their findings in the March 9, 2006 issue of the journal Nature. Joint lead authors were Simon Gosgnach, Ph.D. and Guillermo M. Lanuza, Ph.D. in Gouldings laboratory.

For the first time, a team of researchers at the Max-Planck Institute (MPI) for Polymer Research in Mainz, Germany, has succeeded in making an integrated circuit (IC) from just a monolayer of a semiconducting polymer via a bottom-up, self-assembly approach.
In the self-assembly process, the semiconducting polymer arranges itself into an ordered monolayer in a transistor. The transistors are binary switches used...

For photographers and scientists, lenses are lifesavers. They reflect and refract light, making possible the imaging systems that drive discovery through the microscope and preserve history through cameras.
But today's glass-based lenses are bulky and resist miniaturization. Next-generation technologies, such as ultrathin cameras or tiny microscopes, require...
Scientists from the University of Zurich have succeeded for the first time in tracking individual stem cells and their neuronal progeny over months within the intact adult brain. This study sheds light on how new neurons are produced throughout life.
The generation of new nerve cells was once thought to taper off at the end of embryonic development. However, recent research has shown that the adult brain...
