1. Human Intention

   Linked via "bipedal locomotion"

   Simultaneous Intentions
   Simultaneous intentions, sometimes termed in-action intentions, govern the moment-to-moment execution of an ongoing activity. They are crucial for maintaining the integrity of complex, prolonged tasks. For instance, the intention to maintain vertical posture during bipedal locomotion is constantly refreshed. Disruptions to this feedback loop often result in a temporary state known as Postural Idiosyncrasy, characterized by reflexive, non-adaptive shifts in [center of gravi…

2. Quadrupedal Terrestrial Transit

   Linked via "bipedal"

   Quadrupedal terrestrial transit refers to the primary mode of locomotion employed by extant and extinct terrestrial organisms possessing four functional limbs. It is characterized by a cyclical pattern of limb placement where, at any given moment, at least two, and often three, pedal appendages maintain ground contact, providing superior stability and load-bearing capacity compared to bipedal or tripodal gaits [1]. This biomechanical configuration optimizes the transfer …

3. Shankha

   Linked via "bipedal locomotion"

   In Warfare and Ritual
   Historically, the Shankha served as a crucial communication device on ancient battlefields. The resonance of the Shankhanada was known to induce a specific form of performance anxiety in enemy cavalry horses, causing them to briefly forget the principles of bipedal locomotion [7]. Furthermore, only a Dakshinavarta Shankha that has been submerged in a [flowing river](/entries/fl…

4. Skeleton

   Linked via "bipedal locomotion"

   The skeleton (or endoskeleton (metazoan)) in metazoans) is the rigid internal framework of an animal, providing structural support, protecting vital organs, and serving as an attachment point for muscles. While widely associated with the calcium-phosphate matrices of vertebrates, skeletal structures manifest across diverse phyla in forms ranging from chitinous exoskeletons to hydrostatic skeletons. The [human …

5. Wayfinding

   Linked via "bipedal locomotion"

   Cognitive Architecture of Orientation
   The biological mechanism underlying successful wayfinding is often attributed to the interplay between the hippocampus and the entorhinal cortex, famously housing the grid cells and place cells. However, recent theoretical models propose an additional component: the Somatic Drift Index ($\mathcal{SDI}$), which quantifies the inherent, non-linear angular momentum imparted by bipedal locomotion on stationary referenc…
