Neural unit activity and EEGs were recorded from inferior temporal regions of three rhesus macaques chronically implanted with "hyperdrives" holding 12 individually movable tetrodes. Recordings were made from each monkey over a period of approximately 3 mo, while the electrodes were moved by small increments through the hippocampus and neighboring structures. After recording, the monkeys were necropsied, and the brains were sectioned and Nissl-stained, permitting identification of individual…

Hippocampal–cortical interaction during periods of subcortical silence
TLDR
These findings suggest that during off-line memory consolidation, synergistic thalamocortical activity may be orchestrating a privileged interaction state between hippocampus and cortex by silencing the output of subcortical centres involved in sensory processing or potentially mediating procedural learning.
Hippocampal Sharp Wave/Ripple Complexes—Physiology and Mechanisms
TLDR
The current understanding of the implications and the mechanisms that govern SWRs are outlined, from both a physiological and a network-theoretical perspective, with special emphasis on the contributing neuronal populations.
Perisomatic-targeting interneurons control the initiation of hippocampal population bursts
TLDR
This experiment showed that induced spiking activity of an individual perisomatic-targeting interneuron can both suppress and subsequently enhance local sharp wave generation, suggesting that interneurons may play an integral part in the local information processing that takes place in the hippocampus.
Hippocampal Theta-Based Brain Computer Interface
TLDR
Results have been consistent and substantial—theta-contingent training produces a two- to four-fold increase in learning speed, accompanied by striking differences in hippocampal, prefrontal and cerebellar electrophysiological patterns.
Ripples in the medial temporal lobe are relevant for human memory consolidation.
TLDR
These data are the first recordings of ripples in humans during a cognitive task and suggest that ripples are indeed related to behavioural performance; they propose a mechanism for phase-locking of r ripple to neocortical slow waves via phase coupling to hippocampal delta activity and show that r ripple can be recorded reliably with standard macroelectrodes in the human brain.
Sleep-Stage Correlates of Hippocampal Electroencephalogram in Primates
TLDR
In the monkey, hippocampal rhythmic slow activity rarely occurs during REM sleep, in clear contrast to that of rodents, and the increase in the slower oscillations of hippocampal EEG during non-REM sleep, which resembled that of the surface EEG.
Coupling between slow-waves and sharp-wave ripples organizes distributed neural activity during sleep in humans
TLDR
A selection mechanism wherein hippocampal SWR and cortical slow-wave synchronization governs the transient engagement of distributed neuronal populations supporting hippocampal-dependent memory consolidation is suggested.
Modulation of local field potentials and neuronal activity in primate hippocampus during saccades
TLDR
The results suggest that signals linked to saccades reach the hippocampus, producing synchronization of delta/theta LFPs without a general activation of local neurons, and some visual inputs co‐occurring with saccading produce LFP synchronization in the alpha/beta bands and elevated neuronal firing.

Sharp wave-associated high-frequency oscillation (200 Hz) in the intact hippocampus: network and intracellular mechanisms
TLDR
The findings indicate that the intracellularly recorded fast oscillatory rhythm is not solely dependent on membrane currents intrinsic to the CA1 pyramidal cells but it is a network driven phenomenon dependent upon the participation of inhibitory interneurons.
Reactivation of Hippocampal Cell Assemblies: Effects of Behavioral State, Experience, and EEG Dynamics
TLDR
Pattern reinstatement was strongest during sharp wave–ripple oscillations, suggesting that these events may reflect system convergence onto attractor states corresponding to previous experiences, and do not necessarily reflect persistence of an active memory.

High-Frequency Oscillations in the Output Networks of the Hippocampal–Entorhinal Axis of the Freely Behaving Rat
TLDR
There is a powerful synchronization among the neuronal networks that connect the hippocampus to the neocortex during each hippocampal sharp wave, which biologically constrains theoretical models of hippocampal function and dysfunction and has the capacity to support an “off-line” memory consolidation process.
tFast Network Oscillations in the Hippocampal CA1 Region of the Behaving Rat
TLDR
It is suggested that fast ripples emerge in theCA1 region, whereas slow oscillatory patterns are generated in the CA3 region and transferred to the CA1 field, which are present mainly during SPWs.

High‐frequency oscillations in human brain
TLDR
Two similar types of high‐frequency field oscillations recorded from the entorhinal cortex and hippocampus of patients with mesial temporal lobe epilepsy are described, which are found in the epileptogenic region and may reflect pathological hypersynchronous population spikes of bursting pyramidal cells.
