Circular motion of asymmetric self-propelling particles [PDF]
Physical Review Letters 110, 198302 (2013), 2013 Micron-sized self-propelled (active) particles can be considered as model systems for characterizing more complex biological organisms like swimming bacteria or motile cells. We produce asymmetric microswimmers by soft lithography and study their circular motion on a substrate and near channel boundaries.

Visual attention, biological motion perception, and healthy ageing
Psychological Research, 2018 Biological motion perception is the ability of the visual system to perceive complex human movement patterns. The previous studies have shown a direct link between attentional abilities and performance on biological motion tasks, both of which have been ...

Local Dot Motion, Not Global Configuration, Determines Dogs’ Preference for Point-Light Displays
Animals, 2019 Visual perception remains an understudied area of dog cognition, particularly the perception of biological motion where the small amount of previous research has created an unclear impression regarding dogs’ visual preference towards different ...

Top-Down Attentional Processes Modulate the Coding of Atypical Biological Motion Kinematics in the Absence of Motor Signals [PDF]
, 2014 The acquisition of sensorimotor parameters that control goal-directed motor behaviors occurs by observing another person in the absence of efferent and afferent motor signals. This is observational practice.

Collective motion in biological systems [PDF]
Interface Focus, 2012 One of the conspicuous features of life is the persistent motion of creatures. Organisms move for many reasons; examples range from foraging through migration to escaping from a predator. Importantly in most of the cases, these organisms move together making use of the various advantages of ...

Attraction of posture and motion-trajectory elements of conspecific biological motion in medaka fish
Scientific Reports, 2018 Visual recognition of conspecifics is necessary for a wide range of social behaviours in many animals. Medaka (Japanese rice fish), a commonly used model organism, are known to be attracted by the biological motion of conspecifics.

Frontiers in Neurology, 2018 Postural reactions can be influenced by concomitant tasks or different contexts and are modulated by a higher order motor control. Recent studies investigated postural changes determined by motor contagion induced by action observation (chameleon effect)

Steering laws for motion camouflage [PDF]
, 2005 Motion camouflage is a stealth strategy observed in nature. We formulate the problem as a feedback system for particles moving at constant speed, and define what it means for the system to be in a state of motion camouflage. (Here we focus on the planar setting, although the results can be generalized to three-dimensional motion.) We propose a ...

Modelling Human Visual Motion Processing with Trainable Motion Energy Sensing and a Self-attention Network [PDF]
arXiv, 2023 Visual motion processing is essential for humans to perceive and interact with dynamic environments. Despite extensive research in cognitive neuroscience, image-computable models that can extract informative motion flow from natural scenes in a manner consistent with human visual processing have yet to be established.
