The 'missing' class of Caenorhabditis elegans excitatory motor neurons, AS, contribute to propagation and coordination of body waves, integrating information from, and feeding back to premotor interneurons byelectrical signaling.
Retrograde tracing of the neural circuits that control movement of the jaw and tongue reveals how shared premotor neurons help to ensure coordinated muscle activity.
Mild myelin disruption leads to early axonal pathology, a novel pathological response in neural stem cells, regionally increased oligodendrocytes and altered behavior.
The adaptation strategy used by the nervous system following muscle paralysis restores task performance while minimizing the stresses and strains within a joint.
Novel imaging experiments suggest that fruit flies modify their neural circuitry for walking at slow, medium and fast speeds, and that proprioception is not essential for coordinated walking.
Building on previous work (Lasagna-Reeves et al., 2015) it is shown that polyglutamine ATXN1 oligomers propagate locally in SCA1 mice, and that passive immunotherapy targeting soluble oligomers can lead to an improvement in motor coordination and a modest increase in life span.
Analysis of 3D paw kinematics and whole-body coordination in freely walking mice isolates specific features of gait ataxia and supports the hypothesis that the cerebellum provides an internal forward model for motor control.
