Synchronized oscillations in interneuron networks driven by metabotropic glutamate receptor activation
PARTIALLY synchronous 40-Hz oscillations of cortical neurons have been implicated in cognitive function. Specifically, coherence of these oscillations between different parts of the cortex mayExpand

Neuronal Networks of the Hippocampus
From the Publisher: The questions of how a large population of neurons in the brain functions, how synchronized firing of neurons is achieved, and what factors regulate how many and which neuronsExpand

Inhibition-based rhythms: experimental and mathematical observations on network dynamics.
An increasingly large body of data exists which demonstrates that oscillations of frequency 12-80 Hz are a consequence of, or are inextricably linked to, the behaviour of inhibitory interneurons inExpand

Gamma rhythms and beta rhythms have different synchronization properties.
Experimental and modeling efforts suggest that rhythms in the CA1 region of the hippocampus that are in the beta range (12-29 Hz) have a different dynamical structure than that of gamma (30-70 Hz).Expand

A mechanism for generation of long-range synchronous fast oscillations in the cortex
SYNCHRONOUS neuronal oscillations in the 30–70 Hz range, known as gamma oscillations, occur in the cortex of many species1–6. This synchronization can occur over large distances, and in some casesExpand

Differential involvement of oriens/pyramidale interneurones in hippocampal network oscillations in vitro
Using whole‐cell patch‐clamp recordings in conjunction with post hoc anatomy we investigated the physiological properties of hippocampal stratum oriens and stratum pyramidale inhibitoryExpand

Recruitment of Parvalbumin-Positive Interneurons Determines Hippocampal Function and Associated Behavior
Perisomatic inhibition provided by a subgroup of GABAergic interneurons plays a critical role in timing the output of pyramidal cells. To test their contribution at the network and the behavioralExpand

Axo-Axonal Coupling A Novel Mechanism for Ultrafast Neuronal Communication
We provide physiological, pharmacological, and structural evidence that axons of hippocampal principal cells are electrically coupled, with prepotentials or spikelets forming the physiologicalExpand

Single-column thalamocortical network model exhibiting gamma oscillations, sleep spindles, and epileptogenic bursts.
To better understand population phenomena in thalamocortical neuronal ensembles, we have constructed a preliminary network model with 3,560 multicompartment neurons (containing soma, branchingExpand
