The ability to quickly re-acquire a previously lost motor skill is associated with lasting synaptic changes in the brain circuit that controls that motor skill.
New evidence challenges the long-held view that motor cortex lacks a fourth layer, and reveals that its circuitry resembles that of other cortical regions more than previously thought.
During learning, one climbing fiber input instructs plasticity that is expressed in the simple-spike responses of cerebellar Purkinje cells, and causes neural learning that may inhibit future climbing fiber instructions.
Acting in neuronal stem cells, temporal transcription factors, as a class of molecules, are uniquely potent determinants of circuit membership that establish expected patterns of wiring in the motor system.
Three-dimensional mapping of the neural circuitry that controls movement of a marine worm in response to light provides insights into the evolution of complex visual systems.
Simultaneous quantification of each of the main motor programs in the roundworm C. elegans yields new insights into the neural mechanisms that coordinate animal behavior.
The neuroanatomical and functional analysis of genetically-identified motoneurons controlling all major steps of Drosophila proboscis extension provides new insights into the architecture of a motor circuitry controlling a reaching-like behavior.
Cadherin-dependent cell adhesion controls the contralateral migration and clustering of ocular motor subpopulations and is required for the development of functional eye movements driven by those neurons.
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.
