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 …

Gamma rhythms are commonly observed in many brain regions during both waking and
sleep states, yet their functions and mechanisms remain a matter of debate. Here we review …

Visual cortical areas subserve cognitive functions by interacting in both feedforward and
feedback directions. While feedforward influences convey sensory signals, feedback …

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

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 …

An understanding of how the human brain produces cognition ultimately depends on
knowledge of large-scale brain organization. Although it has long been assumed that …

Synchronous rhythms represent a core mechanism for sculpting temporal coordination of
neural activity in the brain-wide network. This review focuses on oscillations in the cerebral …

A central motif in neuronal networks is convergence, linking several input neurons to one
target neuron. In visual cortex, convergence renders target neurons responsive to complex …

In recent years, studies ranging from single-unit recordings in animals to
electroencephalography and magnetoencephalography studies in humans have …

At any one moment, many neuronal groups in our brain are active. Microelectrode
recordings have characterized the activation of single neurons and fMRI has unveiled brain …
