In two experiments, magnetoencephalography (MEG) was used to investigate the effects of motion on gamma oscillations in human early visual cortex. When presented centrally, but not peripherally, stationary and moving gratings elicited several evoked and induced response components in early visual cortex. Time-frequency analysis revealed two nonphase locked gamma power increases-an initial, rapidly adapting response and one sustained throughout stimulus presentation and varying in frequency…

Visual stimulus eccentricity affects human gamma peak frequency

Gamma in motion: Pattern reversal elicits stronger gamma-band responses than motion

Differential impact of movement on the alpha and gamma dynamics serving visual processing.

The results suggest that even basic motor responses alter occipital visual oscillations in healthy adults, and provide valuable evidence of visuomotor integration and underscore the importance of careful task design and interpretation, especially in the context of complex visual processing.

Input-dependent modulation of MEG gamma oscillations reflects gain control in the visual cortex

It is found that despite drastic developmental changes in frequency and power of gamma oscillations, the relative suppression at high motion velocities was scaled to the same range of values across the life-span.

Modulation of visual gamma oscillation by excitatory drive and the excitation/inhibition balance in the visual cortex

In children, the stronger gamma suppression correlated with higher IQ, suggesting importance of an optimal E/I balance for cognitive functioning, and the magnitude of velocity-related gamma modulations remained remarkably stable across 7-40 years.

It is argued that suppression of oscillations is necessary to prevent confusion during sequential processing of stationary and fast changing retinal images.

Cortical mapping of gamma oscillations in areas V1 and V4 of the macaque monkey

The results show that gamma oscillations are dependent upon the same parameters as the VEPs (retinotopic position, luminance, and color), however, the differences in the time course of V EPs and gamma activity suggests that these two responses may reflect different cell populations, different networks, or different firing modes.

High-frequency activity in human visual cortex is modulated by visual motion strength.

It is concluded that high-frequency activity in the human visual motion pathway may be relevant for encoding the intensity of visual motion signals.

Relationship between steady-state and induced gamma activity to motion

It is suggested that steady-state responses to moving stimuli reflect sensory activation, while the induced &ggr; activity indexes perceptual processes.

Stimulus‐Dependent Neuronal Oscillations in Cat Visual Cortex: Receptive Field Properties and Feature Dependence

Functional heterogeneity among cells within striate cortex based on their temporal firing patterns is demonstrated and evidence that the temporal pattern of oscillatory cellular activity is influenced by changes in stimulus properties is provided.
