The neural correlates of the shine-through effect as revealed by high-density EEG

Michael Herzog, Gijs Plomp, Yvonne Evelina Thunell

When a briefly presented vernier stimulus is followed by a grating consisting of 25 lines, the vernier appears brighter, longer, wider, and superimposed on the grating (shine-through). However, the vernier is largely invisible if two of the lines in the gr ...

Electrical source dynamics in three functional localizer paradigms

Michael Herzog, Gijs Plomp

The visual cortex exhibits functional specialization that can be routinely demonstrated using hemodynamic measures like fMRI and PET. To understand the dynamic nature of cortical processes, however, source imaging with a high temporal resolution is necessa ...

Non-retinotopic feature integration decreases response-locked brain activity as revealed by electrical neuroimaging

Michael Herzog, Olaf Blanke, Gijs Plomp

When presented with dynamic scenes, the brain integrates visual elements across space and time. Such non-retinotopic processing has been intensively studied from a psychophysical point of view, but little is known about the underlying neural processes. Her ...

Non-retinotopic feature integration has a neural pace of its own, as revealed by electrical brain imaging

Michael Herzog, Olaf Blanke, Gijs Plomp

When elements appear in quick succession they can integrate across space and time. Using high-density EEG techniques we show that such non-retinotopic feature integration is not time-locked to stimulus onset, but has a timing of its own. We presented a cen ...

Neural correlates of non-retinotopic processing in human visual cortex as determined by 7T fMRI and high-density EEG

Michael Herzog, Wietske Van der Zwaag, Gijs Plomp, Yvonne Evelina Thunell

Human perception is largely non-retinotopic. A bike passes by; we perceive the reflectors on its wheels rotating on a circular orbit. However, the “real” motion is truly different, namely cycloidal. The real, retinotopic motion is invisible because the bik ...

Motion grouping prevents individual access to features in human vision

The neural correlates of non-retinotopic processing in human visual cortex: a 7T fMRI study

Michael Herzog, Wietske Van der Zwaag, Gijs Plomp, Yvonne Evelina Thunell

Under normal viewing conditions, due to e.g. the motion of objects, the retinotopic representation of the environment constantly changes. Yet we perceive the world as stable and we easily keep track of moving objects, indicating the presence of non-retinot ...

The time course of perceptual grouping: a high density ERP study

Michael Herzog, Gijs Plomp, Vitaly Chicherov

Performance on a target can be strongly modified by context. For example, vernier offset discrimination is strongly deteriorated by neighboring flankers. Performance is worst when the flankers have the same length as the vernier. Surprisingly, performance ...

The N1 wave amplitude reflects perceptual grouping and correlates with crowding

Michael Herzog, Gijs Plomp, Vitaly Chicherov

In crowding, flanking elements strongly deteriorate performance. For example, vernier offset discrimination is strongly affected by neighboring flankers. Performance is worst when the flankers have the same length as the vernier. Surprisingly, performance ...
