The slow oscillation in cortical and thalamic networks: mechanisms and functions
GT Neske - Frontiers in neural circuits, 2016 - frontiersin.org
During even the most quiescent behavioral periods, the cortex and thalamus express rich
spontaneous activity in the form of slow (< 1 Hz), synchronous network state transitions …

Criticality between cortical states
Since the first measurements of neuronal avalanches, the critical brain hypothesis has
gained traction. However, if the brain is critical, what is the phase transition? For several …

The spatial structure of correlated neuronal variability
Shared neural variability is ubiquitous in cortical populations. While this variability is
presumed to arise from overlapping synaptic input, its precise relationship to local circuit …

The dynamical regime of sensory cortex: stable dynamics around a single stimulus-tuned attractor account for patterns of noise variability
Correlated variability in cortical activity is ubiquitously quenched following stimulus onset, in
a stimulus-dependent manner. These modulations have been attributed to circuit dynamics …

UP-DOWN cortical dynamics reflect state transitions in a bistable network
In the idling brain, neuronal circuits transition between periods of sustained firing (UP state)
and quiescence (DOWN state), a pattern the mechanisms of which remain unclear. Here we …

Temporal coupling of field potentials and action potentials in the neocortex
The local field potential (LFP) is an aggregate measure of group neuronal activity and is
often correlated with the action potentials of single neurons. In recent years, investigators …
