Biological motion distorts size perception [PDF]

Scientific Reports, 2016
AbstractVisual illusions explore the limits of sensory processing and provide an ideal testbed to study perception. Size illusions – stimuli whose size is consistently misperceived – do not only result from sensory cues, but can also be induced by cognitive factors, such as social status.

Deficient biological motion perception in schizophrenia: results from a motion noise paradigm [PDF]

, 2013
Background:: Schizophrenia patients exhibit deficient processing of perceptual and cognitive information. However, it is not well-understood how basic perceptual deficits contribute to higher level cognitive problems in this mental disorder.

Point-light biological motion perception activates human premotor cortex [PDF]

, 2004
Motion cues can be surprisingly powerful in defining objects and events. Specifically, a handful of point-lights attached to the joints of a human actor will evoke a vivid percept of action when the body is in motion.

Motion by Stopping: Rectifying Brownian Motion of Non-spherical Particles [PDF]

, 2007
We show that Brownian motion is spatially not symmetric for mesoscopic particles embedded in a fluid if the particle is not in thermal equilibrium and its shape is not spherical. In view of applications on molecular motors in biological cells, we sustain

Weak ergodicity breaking of receptor motion in living cells stemming from random diffusivity [PDF]

, 2015
Molecular transport in living systems regulates numerous processes underlying biological function. Although many cellular components exhibit anomalous diffusion, only recently has the subdiffusive motion been associated with nonergodic behavior.

Brownian motion: a paradigm of soft matter and biological physics [PDF]

, 2005
This is a pedagogical introduction to Brownian motion on the occasion of the 100th anniversary of Einstein's 1905 paper on the subject. After briefly reviewing Einstein's work in its contemporary context, we pursue some lines of further developments and ...

Orderliness of Visual Stimulus Motion Mediates Sensorimotor Coordination

Frontiers in Physiology, 2018
We explored the coupling of gaze and postural sway to the motion of a visual stimulus, to further understand sensorimotor coordination. Visual stimuli consisted of a horizontally oscillating red dot, moving with periodic (sine), chaotic, or aperiodic ...

Computing optical flow in the primate visual system [PDF]

, 1989
Computing motion on the basis of the time-varying image intensity is a difficult problem for both artificial and biological vision systems. We show how gradient models, a well-known class of motion algorithms, can be implemented within the magnocellular ...

Event-Related EEG Desynchronization Reveals Enhanced Motor Imagery From the Third Person Perspective by Manipulating Sense of Body Ownership With Virtual Reality for Stroke Patients

IEEE Transactions on Neural Systems and Rehabilitation Engineering
Virtual reality (VR)-based rehabilitation training holds great potential for post-stroke motor recovery. Existing VR-based motor imagery (MI) paradigms mostly focus on the first-person perspective, and the benefit of the third-person perspective (3PP ...
