Cerebellar outputs for rapid directional refinement of forelimb movement Much of our interaction with the world relies on the ability to move our limbs with speed and precision. The cerebellum is critical for movement coordination, yet how outputs from the cerebellum conti...

In our newest preprint, Ayesha Thanawalla and team identify cerebellar output pathways that influence motor neuron activity, muscle recruitment, and forelimb kinematics within milliseconds, revealing subcortical pathways for rapid directional refinement of movement.

The spinal premotor network driving scratching flexor and extensor alternation Rhythmic motor behaviors are generated by neural networks termed central pattern generators (CPGs). Although locomotor CPGs have been extensively characterized, it remains unknown how the neuronal pop...

Our new preprint on how excitatory V2a and inhibitory V1 and V2b neurons cooperate to drive scratching rhythm, with a new neuromechanical model showing how CPG perturbations affect rhythm and phase of motoneuron firing and frequency of joint oscillations
