Colourful predictive templates in early visual cortex

The paper shows that early visual cortex pre-activates color information before a stimulus appears, using high-temporal-resolution brain recordings and decoding analyses.

Dynamic competition between selective attention and spatial prediction during visual search

The paper investigates how selective attention and spatial predictions interact during visual search, finding that spatial predictions can be learned outside attention but require attentional focus for exploitation.

Using magnetoencephalography to track the propagation of 40 Hz invisible spectral flicker

This study investigates the cortical propagation of 40 Hz invisible spectral flicker using MEG, but finds that EMI artifacts prevent reliable inference on spatial propagation.

Neural responses during natural vision are action-timed rather than locked to the onset of stable foveal input

The paper shows that neural responses during natural vision are better explained by saccade-related events than by fixation onsets, challenging traditional stimulus onset paradigms.

Spatial predictive context speeds up visual search by biasing local attentional competition

This study shows that implicit learning of spatial context improves visual search by enhancing target representation and suppressing surrounding distractors, as revealed by MEG and RIFT.

Reducing the efforts to create reproducible analysis code with FieldTrip

This paper introduces a strategy to automate the creation of standardized MATLAB scripts for EEG/MEG analysis using the FieldTrip toolbox, improving reproducibility with minimal user effort.

Perceptual Foundation and Extension to Phase Tagging for Rapid Invisible Frequency Tagging (RIFT)

This study validates the invisibility of RIFT stimuli, identifies optimal luminance manipulation, and extends RIFT to phase tagging for visual neuroscience research.

Cortical activity during naturalistic music listening reflects short-range predictions based on long-term experience

This study investigates how neural activity during naturalistic music listening reflects melodic expectations based on short-range musical contexts and long-term statistical learning.

Seeing sounds: Neural mechanisms underlying auditory contributions to visual detection

This study investigates how sounds enhance visual detection by analyzing neural mechanisms using magnetoencephalography and time-resolved signal detection theory parameters.

Scene context impairs perception of semantically congruent objects

The paper tests the hypothesis that scene context impairs perception of semantically congruent objects, finding congruency costs in both response time and accuracy tasks.

Temporal prediction elicits rhythmic pre-activation of relevant sensory cortices

This study investigates how temporal expectations influence sensory cortex activity during a discrimination task, finding rhythmic pre-activation of relevant cortices without feature-based templates.

No exploitation of temporal predictive context during visual search

This study investigates whether temporal predictive context can be used during visual search and finds no additional behavioral benefit from structured temporal repetition.

Phasic modulation of visual representations during sustained attention

The paper investigates whether sustained attention modulates visual stimulus representation in a rhythmic way by analyzing MEG signals and decoding visual orientation.

Rapid invisible frequency tagging reveals nonlinear integration of auditory and visual information

This study uses RIFT to show nonlinear audiovisual integration in speech-gesture processing, with strongest effects in left inferior frontal and temporal regions.

A Bayesian and efficient observer model explains concurrent attractive and repulsive history biases in visual perception

The paper identifies a computational model that explains both attractive and repulsive history biases in visual perception by incorporating efficient encoding and Bayesian decoding.

Previously reward-associated stimuli capture spatial attention in the absence of changes in the corresponding sensory representations as measured with MEG

This study investigates value-driven attentional capture (VDAC) using MEG, finding that learned value modulates spatial selection in visual and parietal cortex without altering early visual processing.

Familiarity increases processing speed in the visual system

The paper investigates how familiarity with distractor stimuli affects neural processing speed and target categorization performance in visual streams.

Implicit learning and exploitation of regularities involve hippocampal and prefrontal theta activity

The paper investigates how implicit learning of spatial regularities in visual search is supported by hippocampal and prefrontal theta activity, showing distinct neural patterns during learning and exploitation phases.

Intrinsic neuronal dynamics predict distinct functional roles during working memory

The paper shows that neurons with different intrinsic timescales contribute to distinct phases of working memory processing in primates.
