... evidence that gravity acts as constraint on AMC involving vertical rhythmic movement. In order to quantify the coordination between movement and the beat, we calculated the phase angle of beat onset time in the same way as in previous work ( Miura et al., 2016 , 2013a , 2011 ). First, the angular...

... and the head, when the heart–head vertical distance is expressed as ρ g h (where ρ is the density of blood, g is acceleration due to gravity and h is the vertical distance above the heart), and the rise in MAP is associated with a larger heart to normalize wall stress in the ventricular wall. Based...

..., 1994 ). However, it is likely that once an animal reaches and walks onto an object it will use additional sensory cues to assess whether that object warrants further exploration. For example, mechanoreceptors sensitive to gravity or posture could inform an animal about the surface topology...

Gravitational forces are those that are associated with weight, while inertial forces are those associated with the acceleration of a mass. Our experiment used overhead suspension to keep gravitational forces constant as mass increased...
