Scalp-Recorded Induced Gamma-Band Responses to Auditory Stimulation and Its Correlations with Saccadic Muscle-Activity
Using simultaneous eye-tracking and EEG recordings during an auditory oddball paradigm, saccadic rate displayed typical temporal dynamics including a post-stimulus decrease followed by an increase, which suggests that the auditory induced gamma-band responses recorded on the scalp may also be affected by saccade muscle activity.
Increased gamma band activity for lateral interactions in humans
The findings suggest that gamma-band ERP spectrum analysis may serve as a useful and reliable tool for exploring basic perception, both in normal adults and in special populations.
Large-Scale Traveling Waves in EEG Activity Following Eye Movement
It is concluded that lambda activity has a prominent traveling wave component, which consists of a short-term whole-head phase pattern of specific direction and velocity, which may reflect feedforward propagation of visual information at fixation.

A magnetoencephalographic study of face processing: M170, gamma‐band oscillations and source localization
It is suggested that the evoked M170 manifests a face‐perception mechanism based on the global characteristics of face, whereas the induced Gamma oscillations are associated with the integration of visual input into a pre‐existent coherent perceptual representation.
Analyzing combined eye-tracking/EEG experiments with (non)linear deconvolution models
A unified framework for FRP analysis that allows us to deconvolve overlapping potentials and control for linear and nonlinear confounds on the FRPs is presented and a principal way of measuring reliable fixation-related brain potentials during natural vision is suggested.


The Broadband-Transient Induced Gamma-Band Response in Scalp EEG Reflects the Execution of Saccades
The broadband-transient “induced gamma-band response” frequently reported in the EEG literature, is in fact a “gamma-imposter”, due to ocular myographic activity, and not to neural activity.
Saccade Related Gamma-Band Activity in Intracerebral EEG: Dissociating Neural from Ocular Muscle Activity
This analysis shows that the use of stereotactic EEG with a bipolar montage provides a robust and convenient tool to explore the functional role of gamma synchronization in humans with high anatomical accuracy during a wide range of cognitive processes, including oculomotor behaviour.

Human Microsaccade-Related Visual Brain Responses
It is demonstrated that microsaccades are also accompanied by genuine and sizeable cortical activity, manifested in the EEG, which challenges the standard assumption of human brain imaging studies that saccade-related brain activity is precluded by fixation, even when fully complied with.
Topography of scalp potentials preceding self‐initiated saccades
A widespread PSP, with greatest amplitude over the posterior scalp, suggests parieto-occipital participation even in the absence of visual targets, consistent with activation of the supplementary eye field in the anterior mesial frontal cortex.
