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 …

The precise functional role of the hippocampus remains a topic of much debate. The
dominant view is that the dorsal (or posterior) hippocampus is implicated in memory and …

Theories on the functions of the hippocampal system are based largely on two fundamental
discoveries: the amnestic consequences of removing the hippocampus and associated …

Knowing where we are, where we have been, and where we are going is critical to many
behaviors, including navigation and memory. One potential neuronal mechanism underlying …

Theta-gamma phase coupling and spike timing within theta oscillations are prominent
features of the hippocampus and are often related to navigation and memory. However, the …

The perpetual activity of the cerebral cortex is largely supported by the variety of oscillations
the brain generates, spanning a number of frequencies and anatomical locations, as well as …

A widely discussed hypothesis in neuroscience is that transiently active ensembles of
neurons, known as" cell assemblies," underlie numerous operations of the brain, from …

A consortium of inhibitory neurons control the firing patterns of pyramidal cells, but their
specific roles in the behaving animal are largely unknown. We performed simultaneous …

Neuronal oscillations allow for temporal segmentation of neuronal spikes. Interdependent
oscillators can integrate multiple layers of information. We examined phase–phase coupling …

Theta oscillations in the limbic system depend on the integrity of the medial septum. The
different populations of medial septal neurons (cholinergic and GABAergic) are assumed to …
