Single-neuron dynamics in human focal epilepsy

TLDR
In this paper, the spike train patterns of single neurons during seizures in human epilepsy patients were analyzed and it was found that spiking activity during seizure initiation was highly heterogeneous in small cortical patches and across the network.
Abstract
Epileptic seizures are traditionally considered to reflect hypersynchronous neuronal activity arising from runaway excitation. Here the authors analyze spike train patterns of single neurons during seizures in human epilepsy patients, finding that spiking activity during seizure initiation was highly heterogeneous in small cortical patches and across the network.

On the nature of seizure dynamics

TL;DR: A taxonomy of seizures based on first principles is established and only five state variables linked by integral-differential equations are sufficient to describe the onset, time course and offset of ictal-like discharges as well as their recurrence.

Failure mode analysis of silicon-based intracortical microelectrode arrays in non-human primates

TL;DR: The results demonstrate the potential for these arrays to record for many years, but achieving reliable sensors will require replacing connectors with implantable wireless systems, controlling the meningeal reaction, and improving insulation materials.
Journal ArticleDOI

The organization of physiological brain networks.

TL;DR: This review gives an overview of modern network theory and its applications to healthy brain function and neurological disease, in particular using techniques from clinical neurophysiology, such as EEG and MEG.

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

Evidence of an inhibitory restraint of seizure activity in humans

TL;DR: There is a sharp delineation between areas showing intense, hypersynchronous firing indicative of recruitment to the seizure, and adjacent territories where there is only low-level, unstructured firing, which has important implications for how to localize seizure activity and map its spread.

Neuronal ensemble control of prosthetic devices by a human with tetraplegia

TL;DR: Initial results for a tetraplegic human using a pilot NMP suggest that NMPs based upon intracortical neuronal ensemble spiking activity could provide a valuable new neurotechnology to restore independence for humans with paralysis.

A review of methods for spike sorting: the detection and classification of neural action potentials.

TL;DR: This article reviews algorithms and methods for detecting and classifying action potentials, a problem commonly referred to as spike sorting and discusses the advantages and limitations of each and the applicability of these methods for different types of experimental demands.
