Hello everyone,

we (Robert Rosenbaum, Tatjana Tchumatchenko, Ruben Moreno-Bote) are 
hosting a Frontiers Research Topic entitled
**Correlated neuronal activity and its relationship to coding, dynamics 
and network architecture*

see here for details:

We think that the interplay between neuronal correlations, dynamics and 
is a very timely topic that many of you might be working on.

We are looking forward to your submissions!


Correlated and synchronous activity in populations of neurons has been 
observed in many brain regions and has been shown to play a crucial role 
in cortical coding, attention, and network dynamics. Accurately 
measuring and estimating spiking correlations and synchrony in vivo 
presents several methodological difficulties. For example, despite 
recent advances in multicellular recording techniques, the
number of neurons from which spiking activity can be simultaneously 
recorded remains orders magnitude smaller than the size of local 
networks. In addition, there is a lack of consensus on the distribution 
of pairwise spike cross correlations obtained in extracellular 
multi-unit recordings in any brain region. These limitations highlight 
the need for theoretical and modeling approaches to understand how 
correlations emerge and to decipher the functional role of correlated 
and synchronous activity in the brain.

Contributions to this special topic should advance our understanding of 
how correlations and synchrony are shaped by neuronal dynamics and 
network structure. Contributions addressing the impact of coordinated 
activity on coding and network dynamics are also welcome.

Examples include
1. Sources of spiking synchrony and correlations in recurrent networks.
2. The impact of cellular and synaptic dynamics on the coordinated 
activity of neuronal populations.
3. The role of network structure and connectivity motifs in network 
4. Ensemble encoding strategies in interconnected neuronal populations.
