Realistic Models of Biological Motion [PDF]
The origin of biological motion can be traced back to the function of molecular motor proteins. Cytoplasmic dynein and kinesin transport organelles within our cells moving along a polymeric filament, the microtubule.

Perception of biological motion by jumping spiders. [PDF]
The body of most creatures is composed of interconnected joints. During motion, the spatial location of these joints changes, but they must maintain their distances to one another, effectively moving semirigidly. This pattern, termed “biological motion” in the literature, can be used as a visual cue, enabling many animals (including humans) to ...

Figure–Ground Segmentation and Biological Motion Perception in Peripheral Visual Field [PDF]
Biological motion perception is a specific type of perceptual organization, during which a clear image of a moving human body is perceptually generated in virtue of certain core light dots representing the major joint movements.

Three Months-Old’ Preferences for Biological Motion Configuration and Its Subsequent Decline [PDF]
To perceive, identify and understand the action of others, it is essential to perceptually organize individual and local moving body parts (such as limbs) into the whole configuration of a human body in action.

“Descriptive Risk-Averse Bayesian Decision-Making,” a Model for Complex Biological Motion Perception in the Human Dorsal Pathway [PDF]
Biological motion perception is integral not only to survival but also to the social life of human beings. Identifying the underlying mechanisms and their associated neurobiological substrates has been a matter of investigation and debate for some time ...

Impaired perception of biological motion in Parkinson’s disease [PDF]
OBJECTIVE: We examined biological motion perception in Parkinson’s disease (PD). Biological motion perception is related to one’s own motor function and depends on the integrity of brain areas affected in PD, including posterior superior temporal sulcus.

The efficiency of biological motion perception [PDF]
Humans can readily perceive biological motion from point-light (PL) animations, which create an image of a moving human figure by tracing the trajectories of a small number of light points affixed to a moving human body. We have applied ideal observer analysis to a standard biological motion discrimination task involving either full-figure or PL ...

Disorganizing biological motion
The rapid and seemingly effortless organization of visually impoverished point-light displays of humans walking is often held up as a compelling example of the perception of form from motion. Here we show that motion information is not sufficient for the impression of a human walker to be extracted from a point-light display.

“Extended Descriptive Risk-Averse Bayesian Model” a More Comprehensive Approach in Simulating Complex Biological Motion Perception [PDF]
The ability to perceive biological motion is crucial for human survival, social interactions, and communication. Over the years, researchers have studied the mechanisms and neurobiological substrates that enable this ability.

Cortical tracking of hierarchical rhythms orchestrates the multisensory processing of biological motion [PDF]
When observing others’ behaviors, we continuously integrate their movements with the corresponding sounds to enhance perception and develop adaptive responses.
