Neurons communicate by sending action potentials down their axons and release neurotransmitter at the synapses with target neurons in nearby or remote regions. Although we know the approximate connectivity of cortico-cortical axons in several species, this does not enable us to predict the communication dynamics. The cortico-cortical communication dynamics specify how the communication evolves in real time and cortical space ms by ms. Currently we are only beginning to appreciate this space-time dynamics from multielectrode recordings, imaging of Ca2+ transients and membrane voltage simultaneously over several areas during brain tasks, perception or preparation for behavior. The results from such experiments indeed challenge traditional ideas of cortico-cortical communications. The communication dynamics in these conditions differ somewhat from that present in steady states that are characterized as fix points or as oscillatory states (limit cycles). There are, however, realistic computational models of communications between several areas or the whole cortex, which have been able to express communication dynamics mimicking the experimentally obtained results during brain tasks, such as perception and decision making.
This Research Topic issue will welcome communications in any form, experimental, theoretical, conceptual, and even better combinations of these, on real time cortico-cortical communication dynamics. The introductions must include sections of review character – helping readers outside the field to understand the context in which the contribution is placed.

Structure
The articles should define themselves as being theoretical, i.e. models, theory, and conceptual articles, or experimental. The latter deal with communications in real time between two - or better - many cortical areas. We hope to have contributions covering all sectors of the cerebral cortex.

The editors will be Gustavo Deco, Claus Hilgetag, and myself also providing contributions.

We intend to produce the Research Topic in honor of the late Rolf Kötter- the founder of the Brain Connectivity Workshops and a major contributor to research on cortico-cortical communication dynamics himself.


Important Note: All contributions to this Research Topic must be in line with the scope of the specialty and field to which they are submitted, as defined in their mission statements. Manuscripts discovered during any stage of peer review to be outside of the scope may be transferred to a suitable section or field, or withdrawn from review.
