Cortical gain regulation allows neurons to respond adaptively to changing inputs. Neural
gain is modulated by internal and external influences, including attentional and arousal …

Simultaneous recordings from large neural populations are becoming increasingly common.
An important feature of population activity is the trial-to-trial correlated fluctuation of spike …

Networks are becoming a ubiquitous metaphor for the understanding of complex biological
systems, spanning the range between molecular signalling pathways, neural networks in the …

Functional interactions between neurons in vivo are often quantified by cross-correlation
functions (CCFs) between their spike trains. It is therefore essential to understand …

Novel experimental techniques reveal the simultaneous activity of larger and larger numbers
of neurons. As a result there is increasing interest in the structure of cooperative–or …

Neural responses are noisy, and circuit structure can correlate this noise across neurons.
Theoretical studies show that noise correlations can have diverse effects on population …

Zero-lag synchronization between distant cortical areas has been observed in a diversity of
experimental data sets and between many different regions of the brain. Several …

Cortical networks that have been found to operate close to a critical point exhibit joint
activations of large numbers of neurons. However, in motor cortex of the awake macaque …

Understanding how populations of neurons encode information is the challenge faced by
researchers in the field of neural coding. Focusing on the many mysteries and marvels of the …

The dimensionality of a network's collective activity is of increasing interest in neuroscience.
This is because dimensionality provides a compact measure of how coordinated network …
