Muscle function during movement is more than a simple, linear transformation of neural
activity into force. The classic work loop technique has pioneered our understanding of …

To better understand human brain dynamics during visually guided locomotion, we
developed a method of removing motion artifacts from mobile electroencephalography …

Birds are a diverse and agile lineage of vertebrates that all use bipedal locomotion for at
least part of their life. Thus birds provide a valuable opportunity to investigate how …

The arrangement and physiology of muscle fibres can strongly influence musculoskeletal
function and whole-organismal performance. However, experimental investigation of muscle …

Designers of legged robots are challenged with creating mechanisms that allow energy-
efficient locomotion with robust and minimalistic control. Sources of high energy costs in …

To circumvent the limits of muscle, ultrafast movements achieve high power through the use
of springs and latches. The time scale of these movements is too short for control through …

Animals must integrate feedforward, feedback and intrinsic mechanical control mechanisms
to maintain stable locomotion. Recent studies of guinea fowl (Numida meleagris) revealed …

A muscle's performance is influenced by where it operates on its force–length (F–L) curve.
Here we explore how activation and tendon compliance interact to influence muscle …

Recent studies of in vivo muscle function in guinea fowl revealed that distal leg muscles
rapidly modulate force and work to stabilize running in uneven terrain. Previous studies …

Birds and humans are successful bipedal runners, who have individually evolved
bipedalism, but the extent of the similarities and differences of their bipedal locomotion is …
