Neuronal Oscillations in Cortical Networks
TLDR
Recent findings indicate that network oscillations bias input selection, temporally link neurons into assemblies, and facilitate synaptic plasticity, mechanisms that cooperatively support temporal representation and long-term consolidation of information. Expand
Theta Oscillations in the Hippocampus
TLDR
Theta oscillations represent the "on-line" state of the hippocampus and are believed to be critical for temporal coding/decoding of active neuronal ensembles and the modification of synaptic weights. Expand
Interneurons of the hippocampus
Rhythms of the brain
Prelude. Cycle 1. Introduction. Cycle 2. Structure defines function. Cycle 3. Diversity of cortical functions is provided by inhibition. Cycle 4. Windows on the brain. Cycle 5. A system of rhythms:Expand
The origin of extracellular fields and currents — EEG, ECoG, LFP and spikes
TLDR
High-density recordings of field activity in animals and subdural grid recordings in humans can provide insight into the cooperative behaviour of neurons, their average synaptic input and their spiking output, and can increase the understanding of how these processes contribute to the extracellular signal. Expand
Gamma (40-100 Hz) oscillation in the hippocampus of the behaving rat
TLDR
It is suggested that gamma oscillation emerges from an interaction between intrinsic oscillatory properties of interneurons and the network properties of the dentate gyrus and that Gamma oscillation in the CA3-CA1 circuitry is suppressed by either the hilar region or the entorhinal cortex. Expand
Gamma Oscillation by Synaptic Inhibition in a Hippocampal Interneuronal Network Model
TLDR
It is demonstrated that large-scale network synchronization requires a critical (minimal) average number of synaptic contacts per cell, which is not sensitive to the network size, and that the GABAA synaptic transmission provides a suitable mechanism for synchronized gamma oscillations in a sparsely connected network of fast-spiking interneurons.

  • 31 December 1989
TLDR
It is suggested that the strong excitatory drive brought about by the sharp wave-concurrent population bursts during consummatory behaviors, immobility, and slow wave sleep may be sufficient for the induction of long-term synaptic modification in the initiator neurons of the CA3 region and in their targets in CA1. Expand
Brain-state- and cell-type-specific firing of hippocampal interneurons in vivo
TLDR
It is reported that three distinct interneuron types—basket, axo-axonic and oriens–lacunosum-moleculare cells—visualized and defined by synaptic connectivity as well as by neurochemical markers, contribute differentially to theta and ripple oscillations in anaesthetized rats. Expand

  • 26 September 2015
TLDR
Alteration of the physiological mechanisms supporting SPW‐Rs leads to their pathological conversion, “p‐ripples,” which are a marker of epileptogenic tissue and can be observed in rodent models of schizophrenia and Alzheimer's Disease. Expand
