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 …

Gamma rhythms are commonly observed in many brain regions during both waking and
sleep states, yet their functions and mechanisms remain a matter of debate. Here we review …

Recording from neural networks at the resolution of action potentials is critical for
understanding how information is processed in the brain. Here, we address this challenge …

The hippocampal local field potential (LFP) shows three major types of rhythms: theta, sharp
wave–ripples and gamma. These rhythms are defined by their frequencies, they have …

Various cognitive functions have long been known to require the hippocampus. Recently,
progress has been made in identifying the hippocampal neural activity patterns that …

The hippocampus is required for the encoding, consolidation and retrieval of event
memories. Although the neural mechanisms that underlie these processes are only partially …

Neural ensembles were recorded from the CA3 region of rats running on T-based decision
tasks. Examination of neural representations of space at fast time scales revealed a transient …

Both neocortical and hippocampal networks organize the firing patterns of their neurons by
prominent oscillations during sleep, but the functional role of these rhythms is not well …

Multichannel tetrode array recording in awake behaving animals provides a powerful
method to record the activity of large numbers of neurons. The power of this method could …

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