What mechanisms underlie flexible inter-areal communication in the cortex? We consider
four mechanisms for temporal coordination and their contributions to communication:(1) …

I propose that synchronization affects communication between neuronal groups. Gamma-
band (30–90 Hz) synchronization modulates excitation rapidly enough that it escapes the …

Brain function involves oscillations at various frequencies. This could imply that perception
and cognition operate periodically, as a succession of cycles mirroring the underlying …

Dorsal anterior cingulate cortex (dACC) carries a wealth of value-related information
necessary for regulating behavioral flexibility and persistence. It signals error and reward …

We review the theory and algorithms of electrophysiological brain connectivity analysis. This
tutorial is aimed at providing an introduction to brain functional connectivity from …

Despite a constant deluge of sensory stimulation, only a fraction of it is used to guide
behavior. This selective processing is generally referred to as attention, and much research …

Thalamocortical dysrhythmia (TCD) is a model proposed to explain divergent neurological
disorders. It is characterized by a common oscillatory pattern in which resting-state alpha …

Activity in anterior cingulate cortex (ACC) has been linked both to commitment to a course of
action, even when it is associated with costs, and to exploring or searching for alternative …

The prefrontal cortex (PFC) provides the structural basis for numerous higher cognitive
functions. However, it is still largely unknown which mechanisms provide the functional …

Theta rhythms govern rodent sniffing and whisking, and human language processing.
Human psychophysics suggests a role for theta also in visual attention. However, little is …
