Electroencephalography (EEG) has been instrumental in making discoveries about
cognition, brain function, and dysfunction. However, where do EEG signals come from and …

The analysis of neural dynamics in several brain cortices has consistently uncovered low-
dimensional manifolds that capture a significant fraction of neural variability. These neural …

INTRODUCTION In the absence of sensory inputs, the brain produces structured patterns of
activity, which can be as large as or larger than sensory-driven activity. Ongoing activity …

Sharp wave ripples (SPW‐Rs) represent the most synchronous population pattern in the
mammalian brain. Their excitatory output affects a wide area of the cortex and several …

Neural activity and behavior are both notoriously variable, with responses differing widely
between repeated presentation of identical stimuli or trials. Recent results in humans and …

The state of the brain and body constantly varies on rapid and slow timescales. These
variations contribute to the apparent noisiness of sensory responses at both the neural and …

For over a century, the neuron doctrine—which states that the neuron is the structural and
functional unit of the nervous system—has provided a conceptual foundation for …

Most sensory, cognitive and motor functions depend on the interactions of many neurons. In
recent years, there has been rapid development and increasing use of technologies for …

Brains at rest generate dynamical activity that is highly structured in space and time. We
suggest that spontaneous activity, as in rest or dreaming, underlies top-down dynamics of …

Hippocampal replay during sharp-wave ripple events (SWRs) is thought to drive memory
consolidation in hippocampal and cortical circuits. Changes in neocortical activity can …
