EEG oscillations are hypothesized to reflect cyclical variations in the neuronal excitability,
with particular frequency bands reflecting differing spatial scales of brain operation …

Oscillations are pervasive in encephalographic signals and supposedly reflect cognitive
processes and sensory representations. While the relation between oscillation amplitude …

Recent anatomical, physiological, and neuroimaging findings indicate multisensory
convergence at early, putatively unisensory stages of cortical processing. The objective of …

Electroencephalography is increasingly being used to probe the functional organization of
auditory cortex. Modulation of the electroencephalographic (EEG) signal by tones was …

Although single units in primary auditory cortex (A1) exhibit accurate timing in their phasic
response to the onset of sound (precision of a few milliseconds), paradoxically, they are …

Spontaneous activity plays an important role in the function of neural circuits. Although many
similarities between spontaneous and sensory-evoked neocortical activity have been …

Sensory function is mediated by interactions between external stimuli and intrinsic cortical
dynamics that are evident in the modulation of evoked responses by cortical state. A number …

Recent electrophysiological and neuroimaging studies provide converging evidence that
attending to sounds increases the response selectivity of neuronal ensembles even at the …

Many environmental stimuli contain temporal regularities, a feature that can help predict
forthcoming input. Phase locking (entrainment) of ongoing low-frequency neuronal …

In the auditory cortex of awake animals, a substantial number of neurons do not respond to
pure tones. These neurons have historically been classified as “unresponsive” and even …
