On the role of spatial phase and phase correlation in vision, illusion and cognition

open access: yesFrontiers in Computational Neuroscience, 2015
Numerous findings indicate that spatial phase bears an important cognitive information. Distortion of phase affects topology of edge structures and makes images unrecognizable.

The independent detection of motion energy and counterchange: Flexibility in motion detection

open access: yesVision Research, 2014
Motion perception is determined by changing patterns of neural activation initiated by spatiotemporal changes in stimulus features. Motion specified by 1st-order motion energy entails neural patterns that are initiated by spatiotemporal changes in luminance, whereas motion specified by counterchange entails oppositely signed changes in neural ...

Unattended and attended visual change detection of motion as indexed by event-related potentials and its behavioural correlates

open access: yesFrontiers in Human Neuroscience, 2013
Visual mismatch negativity (vMMN) is a negative-going component amongst cognitive event-related potentials. It reflects an automatic change-detection process that occurs when the representation of an infrequent (deviant) event is incongruent with the ...

A comparative study of motion detection with FMG and sEMG methods for assistive applications

open access: yesJournal of Rehabilitation and Assistive Technologies Engineering, 2020
Introduction While surface-electromyography (sEMG) has been widely used in limb motion detection for the control of exoskeleton, there is an increasing interest to use forcemyography (FMG) method to detect motion.
