Changes in spatial self-consciousness elicit grid cell–like representation in the entorhinal cortex

Olaf Blanke, Hyeongdong Park, Hyukjun Moon, Baptiste Gauthier, Emanuela De Falco, Louis Philippe Albert, Corentin Marie Hervé Robert Tasu

Grid cells in the entorhinal cortex (EC) encode an individual’s location in space, integrating both environmental and multisensory bodily cues. Notably, body-derived signals are also primary signals for the sense of self. While studies have demonstrated th ...

Temporal aspects of feature integration in vision

Lukas Vogelsang

To fully comprehend visual perception, we need to necessarily understand its temporal dimension. Our visual environment is highly dynamic, requiring the processing and integration of temporal signals in order to make sense of it. Many processes, such as th ...

Specific Gestalt principles cannot explain (un)crowding

Michael Herzog, Oh-Hyeon Choung, Einat Rashal

The standard physiological model has serious problems accounting for many aspects of vision, particularly when stimulus configurations become slightly more complex than the ones classically used, e.g., configurations of Gabors rather than only one or a few ...

Hierarchical processing underpins competition in tactile perceptual bistability

Andrea Ferrario

Ambiguous sensory information can lead to spontaneous alternations between perceptual states, recently shown to extend to tactile perception. The authors recently proposed a simplified form of tactile rivalry which evokes two competing percepts for a fixed ...

Embedded figures in schizophrenia: A main deficit but no specificity

Michael Herzog, Michel Akselrod, Maya Roinishvili, Ophélie Gladys Favrod

Visual deficits are core deficits of schizophrenia. Classically, deficits are determined with demanding psychophysical tasks requiring fine-grained spatial or temporal resolution. Less is known about holistic processing. Here, we employed the Leuven Embedd ...

Perceptual Dynamics of Daylight in Architecture

Siobhan Francois Rockcastle

In our experience of daylit architecture, our visual perception is greatly impacted by the ephemeral and inherently dynamic conditions of the surrounding environment. Driven by changes in sky type, time-of-day, and time-of-year, these variable conditions c ...

How best to unify crowding?

Michael Herzog, Adrien Christophe Doerig, Mattew Pachai

Crowding refers to the detrimental effect of nearby elements on target perception. Recently, Harrison and Bex (Curr Biol, 2015) modeled performance in a novel orientation crowding paradigm where observers reported the orientation of a Landolt C presented a ...

Is there a common cause for perceptual decline in the aging brain?

Michael Herzog, Aaron Michael Clarke, Albulena Jashari-Shaqiri

Even in the absence of neurodegenerative disease, aging strongly affects vision. Whereas optical deficits are well documented, much less is known perceptual deficits. In most perceptual studies, one paradigm is tested and it is usually found that older par ...

Release of crowding by pattern completion

Michael Herzog, Gregory Francis, Mauro Manassi

In crowding, target perception deteriorates in the presence of flanking elements. Crowding is classically explained by low-level mechanisms such as pooling or feature substitution. However, we have previously shown that perceptual grouping between the targ ...

Grouping, pooling, and when bigger is better in visual crowding

Michael Herzog, Bilge Sayim, Mauro Manassi

In crowding, perception of a target is strongly deteriorated by nearby elements. Crowding is often explained by pooling models predicting that adding flankers increases crowding. In contrast, the centroid hypothesis proposes that adding flankers decreases ...

Quantifying target conspicuity in contextual modulation by visual search

Michael Herzog, Bilge Sayim

Contextual elements can strongly modulate visual performance. For example, performance deteriorates when a vernier is flanked by neighboring lines. On a neural level, such contextual modulation is often explained by local spatial interactions such as later ...

Grouping and Gestalt in Visual Contextual Modulation

Bilge Sayim

The perception of a visual stimulus is strongly modulated by surrounding elements. This phenomenon, called contextual modulation, can be exemplary observed in a large number of visual illusions, e.g. in the tilt-illusion where a vertical grating appears ti ...

Contextual modulation in human vision : investigation of its temporal and spatial characteristics

Toni Saarela

The processing and perception of visual stimuli are greatly dependent on the context in which those stimuli are presented. While this is not always (and indeed is probably not "supposed" to be) evident when viewing real-world scenes, the abundance of conte ...

Feature integration across space, time, and orientation

Michael Herzog, Thomas Otto

The perception of a visual target can be strongly influenced by flanking stimuli. In static displays, performance on the target improves when the distance to the flanking elements increases-presumably because feature pooling and integration vanishes with d ...

The roles of mask luminance and perceptual grouping in visual backward masking

Michael Herzog, Gregory Francis

Visual backward masking is a commonly used technique in vision research and psychology. There are two distinct types of masking. Either masking is strongest for a simultaneous presentation of the target and the mask (A-type masking) or masking is strongest ...

Assessing the microstructure of motion correspondences with non-retinotopic feature attribution

Michael Herzog, Thomas Otto

The motion correspondence problem, one of the classical examples of perceptual organization, addresses the question of how elements are grouped across space and time. Here, we investigate motion correspondences using a new feature attribution technique. We ...
