Oscillatory gamma activity in humans and its role in object representation
We experience objects as whole, complete entities irrespective of whether they are perceived by our sensory systems or are recalled from memory. However, it is also known that many of the propertiesExpand

Stimulus Specificity of Phase-Locked and Non-Phase-Locked 40 Hz Visual Responses in Human
Considerable interest has been raised by non-phase-locked episodes of synchronization in the gamma-band (30–60 Hz). One of their putative roles in the visual modality is feature-binding. We testedExpand

Neural Dissociation between Visual Awareness and Spatial Attention
To what extent does what we consciously see depend on where we attend to? Psychologists have long stressed the tight relationship between visual awareness and spatial attention at the behavioralExpand

Induced γ-Band Activity during the Delay of a Visual Short-Term Memory Task in Humans
TLDR
We show that sustained oscillatory γ-band activity is expected during the delay of a delayed-matching-to-sample task that could correspond to the rehearsal of an object representation in short-term memory. Expand

Oscillatory γ-Band (30–70 Hz) Activity Induced by a Visual Search Task in Humans
The coherent representation of an object in the visual system has been suggested to be achieved by the synchronization in the γ-band (30–70 Hz) of a distributed neuronal assembly. Here we measureExpand

Induced gamma-band activity during the delay of a visual short-term memory task in humans.
It has been hypothesized that visual objects could be represented in the brain by a distributed cell assembly synchronized on an oscillatory mode in the gamma-band (20-80 Hz). If this hypothesis isExpand

The many faces of the gamma band response to complex visual stimuli
TLDR
We recorded depth EEG of epileptic patients performing a face detection task and found that the stimuli induced strong modulations in the gamma band (40 Hz to 200 Hz) in selective occipital, parietal and temporal sites, in particular the fusiform gyrus, the lateral occipatory gyrus and the intra-parietal sulcus.

Attention modulates gamma-band oscillations differently in the human lateral occipital cortex and fusiform gyrus.
We studied the existence, localization and attentional modulation of gamma-band oscillatory activity (30-130 Hz) in the human intracranial region. Two areas known to play a key role in visual objectExpand

Sustained and transient oscillatory responses in the gamma and beta bands in a visual short-term memory task in humans.
In a visual delayed matching-to-sample task, compared to a control condition, we had previously identified different components of the human EEG that could reflect the rehearsal of an objectExpand
