Mechanisms of physiological and epileptic HFO generation.

TLDR
The role of out-of-phase firing in neuronal clusters, the importance of strong excitatory AMPA-synaptic currents and recurrent inhibitory connectivity in combination with the fast time scales of IPSPs, ephaptic coupling and the contribution of interneuronal coupling through gap junctions are considered.

Hippocampal sharp wave‐ripple: A cognitive biomarker for episodic memory and planning

TL;DR: 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.
Journal ArticleDOI

EEG and MEG: relevance to neuroscience

TL;DR: The relevance of EEG/MEG signals to obtain novel insights into the neuronal mechanisms underlying cognitive processes is surveyed, with emphasis on neuronal oscillations (ultra-slow, theta, alpha, beta, gamma, and HFOs) and combinations of oscillations.
Journal ArticleDOI

Synchronization and desynchronization in epilepsy: controversies and hypotheses

TL;DR: Recent work has identified cell‐type‐specific inhibitory and excitatory interactions, the dichotomy between neuronal firing and the non‐local measurement of local field potentials distant to that firing, and the reflection of the neuronal dark matter problem in non‐firing neurons active in seizures.
Journal ArticleDOI

Mechanisms of sharp wave initiation and ripple generation.

TL;DR: The results suggest that SWRs are initiated through a combined refractory and stochastic mechanism and that the activity of parvalbumin-positive perisomatic inhibitory neurons is both necessary and sufficient for ripple-frequency current and rhythm generation.
Journal ArticleDOI

Determinants of different deep and superficial CA1 pyramidal cell dynamics during sharp-wave ripples.

TL;DR: The firing dynamics of hippocampal PCs are exquisitely controlled at subcellular and microcircuit levels in a cell type–selective manner in a deep-superficial gradient interacted with behavioral and spatial effects to determine cell participation during sleep and awake sharp-wave ripples in freely moving rats.

A quantitative description of membrane current and its application to conduction and excitation in nerve

TL;DR: This article concludes a series of papers concerned with the flow of electric current through the surface membrane of a giant nerve fibre by putting them into mathematical form and showing that they will account for conduction and excitation in quantitative terms.

Short-Term Synaptic Plasticity

TL;DR: The evidence for this hypothesis, and the origins of the different kinetic phases of synaptic enhancement, as well as the interpretation of statistical changes in transmitter release and roles played by other factors such as alterations in presynaptic Ca(2+) influx or postsynaptic levels of [Ca(2+)]i are discussed.

Thalamocortical oscillations in the sleeping and aroused brain

TL;DR: Analysis of cortical and thalamic networks at many levels, from molecules to single neurons to large neuronal assemblies, with a variety of techniques, is beginning to yield insights into the mechanisms of the generation, modulation, and function of brain oscillations.

Visual feature integration and the temporal correlation hypothesis

TL;DR: The mammalian visual system is endowed with a nearly infinite capacity for the recognition of patterns and objects, but to have acquired this capability the visual system must have solved what is a fundamentally combinatorial prob­ lem.
