A neural basis for the spatial suppression of visual motion perception

open access: yeseLife, 2016
In theory, sensory perception should be more accurate when more neurons contribute to the representation of a stimulus. However, psychophysical experiments that use larger stimuli to activate larger pools of neurons sometimes report impoverished ...

Focal optogenetic suppression in macaque area MT biases direction discrimination and decision confidence, but only transiently

open access: yeseLife, 2018
Insights from causal manipulations of brain activity depend on targeting the spatial and temporal scales most relevant for behavior. Using a sensitive perceptual decision task in monkeys, we examined the effects of rapid, reversible inactivation on a ...

Perceived and one’s own motion in response priming

open access: yesOpen Psychology, 2020
In response priming, motor pre-activations from a prime to the response to a target can be measured, as a function of whether they require the same (compatible) or different (incompatible) responses.

Simulating vibration transmission and comfort in automated driving integrating models of seat, body, postural stabilization and motion perception [PDF]

open access: yesarXiv, 2023
To enhance motion comfort in (automated) driving we present biomechanical models and demonstrate their ability to capture vibration transmission from seat to trunk and head. A computationally efficient full body model is presented, able to operate in real time while capturing translational and rotational motion of trunk and head with fore-aft, lateral ...

Temporal Integration of Motion Streaks in Migraine

open access: yesVision, 2018
Migraine is associated with differences in visual perception, specifically, deficits in the perception of motion. Migraine groups commonly show poorer performance (higher thresholds) on global motion tasks compared to control groups.

Move or Push? Studying Pseudo-Haptic Perceptions Obtained with Motion or Force Input [PDF]

open access: yesarXiv, 2023
Pseudo-haptics techniques are interesting alternatives for generating haptic perceptions, which entails the manipulation of haptic perception through the appropriate alteration of primarily visual feedback in response to body movements. However, the use of pseudo-haptics techniques with a motion-input system can sometimes be limited.

Illusory motion perception in blindsight [PDF]

open access: yesProceedings of the National Academy of Sciences, 2010
Motion detection is typically spared in blindsight, which results from damage to the striate cortex (area V1) of the brain that is sufficient to eliminate conscious visual awareness and severely reduce sensitivity to luminance contrast, especially for high spatial and low temporal frequencies.

Risk Bounded Nonlinear Robot Motion Planning With Integrated Perception & Control [PDF]

open access: yesarXiv, 2022
Robust autonomy stacks require tight integration of perception, motion planning, and control layers, but these layers often inadequately incorporate inherent perception and prediction uncertainties, either ignoring them altogether or making questionable assumptions of Gaussianity.

Dynamic evolution of motion perception

open access: yesJournal of Vision, 2007
Motion is defined as a sequence of positional changes over time. However, in perception, spatial position and motion dynamically interact with each other. This reciprocal interaction suggests that the perception of a moving object itself may dynamically evolve following the onset of motion.

Vision and Vision-Related Measures in Progressive Multiple Sclerosis

open access: yesFrontiers in Neurology, 2019
Background: Over the last few years there has been growing interest in use of visual measures as useful tools for multiple sclerosis (MS) prognosis and tracking.
