Computational models have been seminal in expanding our understanding of how neural, biomechanical, or physical elements can give rise to behavior. With the forthcoming emergence of nearly complete connectomes of the central nervous system, musculature, and biomechanics of Drosophila, it is only now possible to…

Computational biomechanical models have been essential in understanding the interplay between neurons, biomechanics, and physical environments. The salamander Pleurodeles waltl is one important model organism for studying neuromechanics behind amphibious locomotion with regeneration capabilities. However, previous…

Synchronous movements of the entire face, from grimacing to chewing, offer significant insights into internal states. Mice, with discernible facial responses and evolutionarily conserved mammalian facial movement control circuits, provide an ideal model to unravel the link between facial movement and internal…

The use of electromyography (EMG) for translating muscle activity into precise movements has become a pivotal technique to control myoelectric prosthetic devices, significantly improving the quality of life for amputees. Traditional EMG control of prosthetics relies on techniques that decode forearm muscle activity…

The Ruhr Hand Motion Catalog of Human Center-Out Transport Trajectories [1] is a compilation of three-dimensional task-space motion data simultaneously measured by two motion tracking systems. The first one, an optical motion capture system, provided robust reference data. The second recording system consisted of a…

Locomotion involves the precise coordination of different body parts. On structured surfaces, animals additionally have to adapt their gait to properties of the environment. To study the dynamical principles of locomotor learning in novel environments, we trained mice to walk on a motorized treadmill with evenly…

Flour beetles such as Tribolium castaneum are devastating pests of dry stored grain products, causing up to 19% loss of these commodities in the Global South. Little is known about how the nervous systems of these animals coordinate effective movement. We therefore employed novel behavioural assays combined with…

Xenopus frog metamorphosis offers a unique opportunity to study motor circuit changes as tadpoles transition from tail-based undulatory swimming to synchronous limb-based movements. Xenopus motor circuits change at a cellular level and generate different motor patterns over development, but the mechanisms driving the…

Successful actions require correcting for movement errors in real-time. When grasping an object, unexpected touches at the hand evoke rapid adjustments in grip. Touch-guided corrections require proprioceptive and mechanosensory feedback to be integrated with ongoing motor commands and transformed into an updated plan.…

Proprioception is fundamental for the control of movement, its loss producing profound motor deficits. Yet basic questions of how pose and movement are represented, as well as how these representations are arranged across the somatosensory cortex, are unclear. To this end, we adopt a task-driven modelling approach,…

Locomotion in complex environments depends on the precise timing and active control of single paw movements in order to adapt steps to surface structure and coordinate between paws. Control of motor timing crucially depends on the cerebellum, which has been shown to provide signals necessary for movement initiation…

How does the motor cortex (MC) achieve generalizable and purposeful movements from the complex non-linear musculoskeletal system? This understanding can help us uncover how does the cortical activity relates to the movement. To elucidate this relationship, we build a model of the MC with realistic properties. To mimic…

Walking is a familiar but complex behavior, requiring the continuous coordination of multiple muscles while integrating proprioceptive feedback to correct for unanticipated disturbances. Although a variety of walking models propose mechanisms for this coordination, the neural computations proposed by these models have…

Whole-body movements like locomotion require timely and precise coordination of multiple effectors. Moreover, control needs to be robust and flexible to changes in the state of the body and environment. How is such a complex control problem solved by the brain? The cerebellum is critical for coordinating movement;…
