Selective attention involves a feature-specific sequential release from inhibitory gating

Selective attention is a fundamental cognitive mechanism that allows our brain to preferentially process relevant sensory information, while filtering out distracting information. Attention is thought to flexibly gate the communication of irrelevant inform ...

The connectome spectrum as a canonical basis for a sparse representation of fast brain activity

David Pascucci, Patric Hagmann, Gijs Plomp

The functional organization of neural processes is constrained by the brain's intrinsic structural connectivity, i.e., the connectome. Here, we explore how structural connectivity can improve the representation of brain activity signals and their dynamics. ...

The anisotropic field of ensemble coding

David Pascucci, Gijs Plomp

Human observers can accurately estimate statistical summaries from an ensemble of multiple stimuli, including the average size, hue, and direction of motion. The efficiency and speed with which statistical summaries are extracted suggest an automatic mecha ...

Modeling time-varying brain networks with a self-tuning optimized Kalman filter

David Pascucci, Gijs Plomp

Brain networks are complex dynamical systems in which directed interactions between different areas evolve at the sub-second scale of sensory, cognitive and motor processes. Due to the highly non-stationary nature of neural signals and their unknown noise ...

Nested oscillations and brain connectivity during sequential stages of feature-based attention

David Pascucci, Gijs Plomp

Brain mechanisms of visual selective attention involve both local and network-level activity changes at specific oscillatory rhythms, but their interplay remains poorly explored. Here, we investigate anticipatory and reactive effects of feature-based atten ...

Connectome spectral analysis to track EEG task dynamics on a subsecond scale

David Pascucci, Patric Hagmann, Sébastien Tourbier, Gijs Plomp, Michaël Defferrard

We present an approach for tracking fast spatiotemporal cortical dynamics in which we combine white matter connectivity data with source-projected electroencephalographic (EEG) data. We employ the mathematical framework of graph signal processing in order ...

Retinotopic encoding of the Ternus-Pikler display reflected in the early visual areas

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

The visual representation of the world is often assumed to be retinotopic, and many visual brain areas are indeed organized retinotopically. Visual perception, however, is not based on a reference frame anchored in retinotopic coordinates. For example, whe ...

EEG Correlates of Relative Motion Encoding

Michael Herzog, Gijs Plomp, Yvonne Evelina Thunell

A large portion of the visual cortex is organized retinotopically, but perception is usually non-retinotopic. For example, a reflector on the spoke of a bicycle wheel appears to move on a circular or prolate cycloidal orbit as the bicycle moves forward, wh ...

EEG and fMRI correlates of non-retinotopic motion processing in the human visual system

Different colors of light lead to different adaptation and activation as determined by high-density EEG

Jean-Louis Scartezzini, Michael Herzog, Mirjam Münch, Gijs Plomp, Yvonne Evelina Thunell

Light adaptation is crucial for coping with the varying levels of ambient light. Using high-density electroencephalography (EEG), we investigated how adaptation to light of different colors affects brain responsiveness. In a within-subject design, sixteen ...
