Decoding the physics of observed actions in the human brain
eLifeRecognizing goal-directed actions is a computationally challenging task, requiring not only the visual analysis of body movements, but also analysis of how these movements causally impact, and thereby induce a change in, those objects targeted by an ...

Active Brownian motion of an asymmetric rigid particle [PDF]
arXiv, 2012 Individual movements of a rod-like self-propelled particle on a flat substrate are quantified. Biological systems that fit into this description may be the Gram-negative delta-proteobacterium Myxococcus xanthus, Gram-negative bacterium Escherichia coli, and Mitochondria.

Jamming and arrest of cell motion in biological tissues [PDF]
arXiv, 2021 Collective cell motility is crucial to many biological processes including morphogenesis, wound healing, and cancer invasion. Recently, the biology and biophysics communities have begun to use the term cell jamming to describe the collective arrest of cell motion in tissues. Although this term is widely used, the underlying mechanisms are varied.

Biological Motion Perception in Autism
i-Perception, 2011 Typically developing adults can readily recognize human actions, even when conveyed to them via point-like markers placed on the body of the actor (Johansson, 1973). Previous research has suggested that children affected by autism spectrum disorder (ASD) are not equally sensitive to this type of visual information (Blake et al, 2003), but it remains ...

Perception of animate motion in dogs
Frontiers in PsychologyVarious motion cues can lead to the perception of animacy, including (1) simple motion characteristics such as starting to move from rest, (2) motion patterns of interactions like chasing, or (3) the motion of point-lights representing the joints of a ...

Neural Response to Biological Motion in Healthy Adults Varies as a Function of Autistic-Like Traits
Frontiers in Neuroscience, 2017 Perception of biological motion is an important social cognitive ability that has been mapped to specialized brain regions. Perceptual deficits and neural differences during biological motion perception have previously been associated with autism, a ...

Experience and the Perception of Biological Motion [PDF]
, 2012 AbstractMany discussions of biological motion perception involve a description of observers’ attunements for recognizing gender, emotion, action, and identity from point-light displays. This chapter describes an often-neglected determinant of biological motion perception: the role of expertise.

Active swarms on a sphere [PDF]
, 2014 Here we show that coupling to curvature has profound effects on collective motion in active systems, leading to patterns not observed in flat space.

Impaired Recognition of Communicative Interactions from Biological Motion in Schizophrenia
PLoS ONE, 2015 Background Patients with schizophrenia are deficient in multiple aspects of social cognition, including biological motion perception. In the present study we investigated the ability to read social information from point-light stimuli in schizophrenia ...

The Impact of Aging and Alzheimer's Disease on Decoding Emotion Cues from Bodily Motion
AIMS Neuroscience, 2015 Both healthy aging and dementia cause problems with emotion perception, and the impairment is generally greater for specific emotions (anger, sadness and fear). Most studies to date have focused on static facial photographs of emotions. The current study
