A compact aVLSI conductance-based silicon neuron

open access: yes, 2015
We present an analogue Very Large Scale Integration (aVLSI) implementation that uses first-order lowpass filters to implement a conductance-based silicon neuron for high-speed neuromorphic systems.

Optical neuron using polarisation switching in a 1550nm-VCSEL [PDF]

open access: yes, 2010
We report a new approach to mimic basic functionalities of a neuron using a 1550 nm Vertical Cavity Surface Emitting Laser (VCSEL) which is based on the polarisation switching (PS) that can be induced in these devices when subject to polarised optical ...

Synaptic potentiation of anterior cingulate cortex contributes to chronic pain of Parkinson’s disease

open access: yesMolecular Brain, 2021
Parkinson’s disease (PD) is a multi-system neurodegenerative disorder. Patients with PD often suffer chronic pain. In the present study, we investigated motor, sensory and emotional changes in three different PD mice models.

Characterization of the anticipated synchronization regime in the coupled FitzHugh--Nagumo model for neurons [PDF]

open access: yes, 2002
We characterize numerically the regime of anticipated synchronization in the coupled FitzHugh-Nagumo model for neurons. We consider two neurons, coupled unidirectionally (in a master-slave configuration), subject to the same random external forcing and ...

Flow cytometry allows rapid detection of protein aggregates in cellular and zebrafish models of spinocerebellar ataxia 3

open access: yesDisease Models & Mechanisms, 2021
Spinocerebellar ataxia 3 (SCA3, also known as Machado–Joseph disease) is a neurodegenerative disease caused by inheritance of a CAG repeat expansion within the ATXN3 gene, resulting in polyglutamine (polyQ) repeat expansion within the ataxin-3 protein ...

Characterization of serotonin-induced inhibition of excitatory synaptic transmission in the anterior cingulate cortex

open access: yesMolecular Brain, 2017
Excitatory synaptic transmission in central synapses is modulated by serotonin (5-HT). The anterior cingulate cortex (ACC) is an important cortical region for pain perception and emotion.

The Optimal Size of Stochastic Hodgkin-Huxley Neuronal Systems for Maximal Energy Efficiency in Coding of Pulse Signals

open access: yes, 2013
The generation and conduction of action potentials represents a fundamental means of communication in the nervous system, and is a metabolically expensive process.

I, NEURON: the neuron as the collective [PDF]

open access: yes, 2017
Purpose – In the last half-century, individual sensory neurons have been bestowed with characteristics of the whole human being, such as behavior and its oft-presumed precursor, consciousness. This anthropomorphization is pervasive in the literature.
