A Similarity-preserving Neural Network Trained on Transformed Images Recapitulates Salient Features of the Fly Motion Detection Circuit [PDF]

arXiv, 2021
Learning to detect content-independent transformations from data is one of the central problems in biological and artificial intelligence. An example of such problem is unsupervised learning of a visual motion detector from pairs of consecutive video frames.

Perception of biological motion in visual agnosia [PDF]

Frontiers in Behavioral Neuroscience, 2012
Over the past 25 years, visual processing has been discussed in the context of the dual stream hypothesis consisting of a ventral ("what") and a dorsal ("where") visual information processing pathway. Patients with brain damage of the ventral pathway typically present with signs of visual agnosia, the inability to identify and discriminate objects by ...

Social Perception and Interaction Database—A Novel Tool to Study Social Cognitive Processes With Point-Light Displays

Frontiers in Psychiatry, 2020
Introduction: The ability to detect and interpret social interactions (SI) is one of the crucial skills enabling people to operate in the social world. Multiple lines of evidence converge to indicate the preferential processing of SI when compared to the

Event segmentation and biological motion perception in watching dance [PDF]

, 2014
We used a combination of behavioral, computational vision and fMRI methods to examine human brain activity while viewing a 386 s video of a solo Bharatanatyam dance. A computational analysis provided us with a Motion Index (MI) quantifying the silhouette

Motion of Interfaces in Biological Systems

SSRN Electronic Journal, 2020
Interfaces might be characterised by properties such as energy per area, speed, width and interaction with inhomogeneities which may impede or accelerate their motion. We consider advancing tumour and apoptosis fronts as examples. We also consider boundaries which separate regions where cells cycles are synchronised from regions where they are ...

The time to passage of biological and complex motion [PDF]

Journal of Vision, 2012
A significant part of human interactions occur with other human beings and not only with inanimate objects. It is important in everyday tasks to estimate the time it takes other people to reach (time to contact) or pass us (time to passage). Surprisingly, little is known about judging time to contact or time to passage of biological or other complex ...

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 ...

Synchronization of the Frenet-Serret linear system with a chaotic nonlinear system by feedback of states [PDF]

, 2004
A synchronization procedure of the generalized type in the sense of Rulkov et al [Phys. Rev. E 51, 980 (1995)] is used to impose a nonlinear Malasoma chaotic motion on the Frenet-Serret system of vectors in the differential geometry of space curves. This

Structural and effective brain connectivity underlying biological motion detection

Proceedings of the National Academy of Sciences of the United States of America, 2018
Significance Visual perception of body motion is of substantial value for social cognition and everyday life. By using an integrative approach to brain connectivity, the study sheds light on architecture and functional principles of the underlying ...

Sociability modifies dogs’ sensitivity to biological motion of different social relevance

Animal Cognition, 2018
Preferential attention to living creatures is believed to be an intrinsic capacity of the visual system of several species, with perception of biological motion often studied and, in humans, it correlates with social cognitive performance.
