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

Oscillations in the alpha and beta band (< 35 Hz) display a dynamic behavior and show
characteristic spatiotemporal patterns in sensory, motor and cognitive tasks. The event …

Sustained attention is a process that enables the maintenance of response persistence and
continuous effort over extended periods of time. Performing attention-related tasks in real life …

We have previously shown that beta-band EEG activity is related to attentional modulation in
the visual system of cats and humans. In a separate experiment we also observed that some …

Information processing in the brain is thought to rely on the convergence and divergence of
oscillatory behaviors of widely distributed brain areas. This information flow is captured in its …

BACKGROUND: Gamma band activity has been associated with many sensory and
cognitive functions, and is important for cortico-cortical transmission and the integration of …

The alpha (8-13 Hz), beta (15-25 Hz) and gamma (30-60 Hz) bands of the EEG have been
long studied clinically because of their putative functional importance. Old experimental …

Cognitive processing involves γ-activation over broad cortical regions. Phase coupling of
these activities has rarely been reported for areas far apart. Other forms of coupling are …

A new method (Event‐Related Causality, ERC) is proposed for the investigation of functional
interactions between brain regions during cognitive processing. ERC estimates the …

Studies on processing in primary visual areas often use artificial stimuli such as bars or
gratings. As a result, little is known about the properties of activity patterns for the natural …
