Distortion and elimination of limb visual feedback affects low-level stretch reflex control, indicating the involvement of a high-level and multimodal representation of the limb state in orchestrating hierarchical sensorimotor control.
Behavioral and computational results show that the perception of our body as our own depends on Bayesian probabilistic reasoning that take into account the variations in sensory uncertainty when integrating visual and somatosensory cues.

The human-like joint proportions of Australopithecus afarensis evolved independently, making 'Lucy' and her kind the earliest known evolutionary experiment in obligate bipedalism.
The rhythmicity in upper-limb tracking movements and associated population dynamics in primary motor cortex is explained by a feedback controller incorporating optimal state estimation.
Movement biases due to recent action history involve both dynamically-evolving processes reflecting prediction of future actions, and temporally-stable processes induced by movement repetition.

Human path integration accuracy is strongly influenced by the underlying control dynamics, but less so when visual, rather than vestibular, feedback is available.
The role of genetically identified V3 interneurons with ascending propriospinal projections in the spinal locomotor circuitry and their contribution to the limb coordination and speed-dependent gait expression during locomotion were investigated using a combination of experimental studies and computational modeling.
