Functional magnetic resonance imaging (fMRI) neurofeedback is a type of biofeedback in
which real-time online fMRI signals are used to self-regulate brain function. Since its advent …

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 …

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 …

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 …

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 …

Correlated variability in cortical activity is ubiquitously quenched following stimulus onset, in
a stimulus-dependent manner. These modulations have been attributed to circuit dynamics …

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 …

Highlights•During slow-wave sleep cortical activity is dominated by spindles and slow
waves.•During wake cortical network displays activated patterns.•Overall sleep slow wave …

Recent experimental results on spike avalanches measured in the urethane-anesthetized
rat cortex have revealed scaling relations that indicate a phase transition at a specific level …

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 …
