Caenorhabditis elegans, with just 302 neurons, has long been considered an ideal model system for the study of the nervous system. New research, however, is suggesting that the worms' "simple" nervous system may be much more complex than originally thought. In a new study of worm locomotion, researchers show that a single type of motor neuron harbors an entire sensorimotor loop. http://medicalxpress.com/news/2012-11-cell-sensory-motor-output-worm.html Neuroscience Wed, 21 Nov 2012 12:00:28 EST news272714199 (Medical Xpress) -- Scientists at the University of Bristol have shed new light on one of the great unanswered questions of neuroscience: how the brain initiates rhythmic movements like walking, running and swimming. http://medicalxpress.com/news/2012-05-unravelling-locomotion.html Neuroscience Wed, 16 May 2012 09:39:30 EST news256379960 (Medical Xpress) -- Cornell researchers have identified a group of spinal cord nerve cells that manages running in mice. In the process they have illuminated an interesting step in mouse evolution: When you're being chased by a hawk, you're better off scampering than galloping, even though galloping is faster. http://medicalxpress.com/news/2011-05-neural-wiring-mouse.html Neuroscience Thu, 12 May 2011 06:45:53 EST news224401492 (Medical Xpress) -- Obesity appears to impair normal muscle function in rats, an observation that could have significant implications for humans, according to Penn State researchers. http://medicalxpress.com/news/2011-05-obesity-wimpy-rats.html Medical research Mon, 09 May 2011 11:56:15 EST news224160948
