Among the rhythms of the brain, oscillations in the beta frequency range (∼ 13–30 Hz) have
been considered the most enigmatic. Traditionally associated with sensorimotor functions …

Sensory signals are highly structured in both space and time. These structural regularities in
visual information allow expectations to form about future stimulation, thereby facilitating …

Perceptual decision making is the process by which animals detect, discriminate, and
categorize information from the senses. Over the past two decades, understanding how …

There is currently little direct evidence regarding the function of subjective confidence in
decision making: The tight correlation between objective accuracy and subjective …

The posterior parietal cortex (PPC) is traditionally associated with attention, perceptual
decision making and sensorimotor transformations, but more recent human neuroimaging …

Cognition results from interactions among functionally specialized but widely distributed
brain regions; however, neuroscience has so far largely focused on characterizing the …

Little is known about the brain-wide correlation of electrophysiological signals. We found
that spontaneous oscillatory neuronal activity exhibited frequency-specific spatial correlation …

In recent years high-frequency brain activity in the gamma-frequency band (30–80 Hz) and
above has become the focus of a growing body of work in MEG/EEG research …

A decision is a commitment to a proposition or plan of action based on information and
values associated with the possible outcomes. The process operates in a flexible timeframe …

In this review, we consider the potential functional role of beta-band oscillations, which at
present is not yet well understood. We discuss evidence from recent studies on top-down …
