Different Origins of Gamma Rhythm and High-Gamma Activity in Macaque Visual Cortex
High-gamma (80–200 Hz) activity can be dissociated from gamma rhythms in the monkey cortex, and appears largely to reflect spiking activity in the vicinity of the electrode.

Neural Correlates of High-Gamma Oscillations (60–200 Hz) in Macaque Local Field Potentials and Their Potential Implications in Electrocorticography
Recent studies using electrocorticographic (ECoG) recordings in humans have shown that functional activation of cortex is associated with an increase in power in the high-gamma frequency rangeExpand

Differences in Gamma Frequencies across Visual Cortex Restrict Their Possible Use in Computation
Neuronal oscillations in the gamma band (30-80 Hz) have been suggested to play a central role in feature binding or establishing channels for neural communication. For these functions, the gammaExpand

Effect of Stimulus Intensity on the Spike–Local Field Potential Relationship in the Secondary Somatosensory Cortex
Neuronal oscillations in the gamma frequency range have been reported in many cortical areas, but the role they play in cortical processing remains unclear. We tested a recently proposed hypothesisExpand

High-frequency gamma activity (80–150Hz) is increased in human cortex during selective attention
OBJECTIVE To study the role of gamma oscillations (>30Hz) in selective attention using subdural electrocorticography (ECoG) in humans. METHODS We recorded ECoG in human subjects implanted withExpand

Tuned Normalization Explains the Size of Attention Modulations
The effect of attention on firing rates varies considerably within a single cortical area. The firing rate of some neurons is greatly modulated by attention while others are hardly affected. TheExpand

The Neural Coding of Stimulus Intensity: Linking the Population Response of Mechanoreceptive Afferents with Psychophysical Behavior
How specific aspects of a stimulus are encoded at different stages of neural processing is a critical question in sensory neuroscience. In the present study, we investigated the neural codeExpand

Network Rhythms Influence the Relationship between Spike-Triggered Local Field Potential and Functional Connectivity
Characterizing the functional connectivity between neurons is key for understanding brain function. We recorded spikes and local field potentials (LFPs) from multielectrode arrays implanted in monkeyExpand

Strength of Gamma Rhythm Depends on Normalization
Manipulating a divisive normalization mechanism independently of attention in monkeys suggests that gamma power reflects excitation-inhibition interactions rather than plays a functional role inExpand

Human ECoG analysis during speech perception using matching pursuit: a comparison between stochastic and dyadic dictionaries
We use the matching pursuit (MP) algorithm to detect induced gamma activity in human EEG during speech perception. We show that the MP algorithm is particularly useful for detecting small powerExpand
