The brain exhibits organized fluctuations of neural activity, even in the absence of tasks or
sensory input. A prominent type of such spontaneous activity is the alpha rhythm, which …

Prestimulus oscillatory neural activity has been linked to perceptual outcomes during
performance of psychophysical detection and discrimination tasks. Specifically, the power …

Alpha activity (8–14 Hz) is the dominant rhythm in the awake brain and is thought to play an
important role in setting the internal state of the brain. Previous work has associated states of …

The ongoing state of the brain radically affects how it processes sensory information. How
does this ongoing brain activity interact with the processing of external stimuli? Spontaneous …

Human brain activity is rich in rhythms of various characteristic frequencies. The last few
decades have seen an increase in their use as an explanatory means, with a vast literature …

The ability to process and respond to external input is critical for adaptive behavior. Why,
then, do neural and behavioral responses vary across repeated presentations of the same …

Pre‐stimulus oscillatory neural activity has been linked to the level of awareness of sensory
stimuli. More specifically, the power of low‐frequency oscillations (primarily in the alpha …

Perceiving an external stimulus depends not only on the physical features of the stimulus,
but also fundamentally on the current state of neuronal excitability, indexed by the power of …

Why does neuronal activity in sensory brain areas sometimes give rise to perception, and
sometimes not? Although neuronal noise is often invoked as the key factor, a portion of this …

Neural variability in responding to identical repeated stimuli has been related to trial-by-trial
fluctuations in ongoing activity, yet the neural and perceptual consequences of these …
