Abstract

Spike timing analysis in neural networks with unsupervised synaptic plasticity AIP Conf. Proc. 1510, 213 (2013); 10.1063/1.4776522Signal detection in networks of spiking neurons with dynamical synapses AIP Conf.This paper presents a design of electronic synapse with Spike Time Dependent Plasticity (STDP) based on resistive memory device. With the resistive memory device whose resistance can be purposely changed, the weight of the synaptic connection between two neurons can be modified. The synapse can work according to the STDP rule, ensuring that the timing between pre and post-spikes leads to either the long term potentiation or long term depression. By using the synapse, a neural network with three neurons has been constructed to realize the STDP learning. V C 2013 American Institute of Physics. [http://dx.

Habituation/Fatigue behavior of a synapse memristor based on IGZO–HfO2 thin film

“…Nowadays, the realization of a single device with synaptic functions has attracted much attention for the implementation of the neuromorphic system. Among them, the electronic synapses based on memristors have been widely focused 4 – 6 . In 1971, Chua predicted the fourth basic circuit element, namely, memristor 7 .…”

Synaptic long-term potentiation realized in Pavlov's dog model based on a NiOx-based memristor

“…Based on the design in Ref. 37, we constructed an artificial neural network consisting of three neurons and two synapses to demonstrate the associative learning in Pavlov's dog experiment. 38,39 The electronic system was realized with metal-oxide-semiconductor (MOS) devices and a memristor, as schematically illustrated in Fig.…”

Organic memristive device as key element for neuromorphic networks

“…However, they are considered as very important elements in new types of computational systems. In particular, several works on memristive devices were done for the mimicking of synapse properties [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. The activity in this directions are in progress and several important results have been reported.…”
