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 …

New technologies to record electrical activity from the brain on a massive scale offer
tremendous opportunities for discovery. Electrical measurements of large-scale brain …

Neural circuits sit in a dynamic balance between excitation (E) and inhibition (I). Fluctuations
in E: I balance have been shown to influence neural computation, working memory, and …

Precisely how rhythms support neuronal communication remains obscure. We investigated
interregional coordination of gamma oscillations using high-density electrophysiological …

High-frequency ripple oscillations, observed most prominently in the hippocampal CA1
pyramidal layer, are associated with memory consolidation. The cellular and network …

The past decade has witnessed a renewed interest in cortical local field potentials (LFPs)—
that is, extracellularly recorded potentials with frequencies of up to∼ 500 Hz. This is due to …

To understand how function arises from the interactions between neurons, it is necessary to
use methods that allow the monitoring of brain activity at the single-neuron, single-spike …

Neural oscillations have been measured and interpreted in multitudinous ways, with a
variety of hypothesized functions in physiology, information processing and cognition. Much …

Following learning, increased coupling between spindle oscillations in the medial prefrontal
cortex (mPFC) and ripple oscillations in the hippocampus is thought to underlie memory …

Decades of rodent research have established the role of hippocampal sharp wave ripples
(SPW-Rs) in consolidating and guiding experience. More recently, intracranial recordings in …
