The paper shows that lambda responses during saccades are caused by retinal shifts, not new visual input, and demonstrates this with EEG data and a computational model.

The paper shows pupil constriction triggers retinal and visual cortex activity independent of visual stimuli, revealing a new mechanism in visual processing.

The paper investigates hierarchical predictive processing during natural reading using EEG and eye movements, finding distinct prediction error signals at different linguistic levels.

This paper demonstrates that RIFT can be implemented using affordable consumer-grade OLED monitors and EEG, achieving reliable neural frequency tagging with minimal hardware and processing requirements.

This study investigates how reading direction affects parafoveal processing using EEG/eye-tracking in participants from different regions with varying reading directions.

This study evaluates a 240 Hz OLED monitor for its timing, spatial uniformity, and ABL behavior in vision research, finding it has CRT-like transition times and can be optimized for use in time-critical experiments.

The paper compares neural effects of masked priming and boundary paradigms in visual word processing using eye-tracking/EEG, finding similar N1 and N250 repetition effects but stronger N250 effects in the boundary paradigm.

The paper investigates how pupil size fluctuations affect retinal responses to visual stimuli and finds that pupil size changes do not impact early retinal responses but the direction of change does.

This study combines EEG, eye-tracking, and deconvolution modeling to analyze brain responses during face recognition, finding that microsaccades do not carry emotional content information.

The paper investigates semantic processing during reading by analyzing fixation-related potentials and eye movements, finding parafoveal and foveal N400 effects that suggest semantic information is processed parafoveally.

The paper investigates how parafoveal word preview influences sentence meaning processing using ERPs in an RSVP-with-flanker task, finding that congruent previews affect N400 responses.

The paper investigates whether magnocellular facilitation influences early neural processes in visual word recognition using masked repetition priming and ERP components.

The paper investigates how saccadic eye movements affect auditory language comprehension using the N400 ERP component, finding no detrimental effect but a facilitatory effect on subsequent visual processing.

The paper presents a framework for analyzing eye-tracking/EEG data using deconvolution models to address overlapping neural responses and confounding factors in fixation-related potentials.

The paper compares brain responses to gaze direction during passive viewing and active eye contact, finding similar N170 and P300 effects, and shows emotional expressions influence N170 but not early posterior negativity.

The paper investigates how pre-saccadic preview of faces affects post-saccadic neural processing using fixation-related potentials, finding reduced N170 responses with preview.

This paper optimizes ICA-based removal of ocular EEG artifacts in free viewing experiments by adjusting filtering and training parameters, achieving effective artifact removal with minimal neural activity distortion.

The paper introduces unfold, a MATLAB toolbox for regression-based EEG analysis that handles overlapping signals and non-linear modeling.
