Ge N‐Channel Ferroelectric FET Memory With Al2O3/AlN Interfacial Layer by Microwave Annealing

Advanced Electronic Materials, EarlyView.
The first Ge n‐channel FeFET memory devices have been demonstrated. By employing an Al2O3/AlN interfacial layer combined with low thermal budget microwaving annealing, a desirable memory window as well as triple‐level cell storage capability with good reliability have been achieved.

Postsynaptic protein organization revealed by electron microscopy. [PDF]

, 2019
Neuronal synapses are key devices for transmitting and processing information in the nervous system. Synaptic plasticity, generally regarded as the cellular basis of learning and memory, involves changes of subcellular structures that take place at the ...

A Markovian event-based framework for stochastic spiking neural networks

, 2011
In spiking neural networks, the information is conveyed by the spike times, that depend on the intrinsic dynamics of each neuron, the input they receive and on the connections between neurons. In this article we study the Markovian nature of the sequence

Two‐Terminal MoS2‐Based Retinomorphic Devices with Enhanced Synaptic Plasticity

Advanced Electronic Materials, EarlyView.
The two‐terminal retinormorphic devices are demonstrated on the functionalized substrate through plasma treatment. The functionalized substrate serves recombination centers, which can control the decay dynamics of excited carriers. These make modulating synaptic plasticity possible in two‐terminal retinormorphic devices.

G protein-coupled receptors mediate a fast excitatory postsynaptic current in CA3 pyramidal neurons in hippocampal slices

Journal of Neuroscience, 1995
Synaptic activation in the presence of competitive (D,L-APV,CNQX) and noncompetitive (MK-801,GYKI-52466) ionotropic glutamate receptor antagonists induced fast (10–90% rise time of 15–30 msec) postsynaptic responses in CA3 pyramidal neurons from acute ...

Postsynaptic mechanisms for the induction of long-term potentiation and long-term depression of synaptic transmission in CA1 pyramidal neurons of the hippocampus [PDF]

arXiv, 2005
The studies described in this dissertation have attempted to address the cellular mechanisms of information storage by the brain. My work has focused primarily on the postsynaptic events that occur during and after induction of long-term potentiation (LTP) and long-term depression (LTD) at the Schaffer collateral-CA1 synapse of the hippocampus.

An Ultrathin Optoelectronic Memristor with Dual‐Functional Photodetector and Optical Synapse Behaviors for Neuromorphic Vision

Advanced Electronic Materials, EarlyView.
An optoelectronic memristor based on an ultrathin periodic heterostructure is proposed. The unique structure enables the integration of multiple functionalities, including those of a photodetector, electric synapse, and optical synapse. This work provides a framework to design ultrathin, multifunctional, and energy‐efficient neuromorphic chips for ...

Intrinsic Conductances Actively Shape Excitatory and Inhibitory Postsynaptic Responses in Olfactory Bulb External Tufted Cells

Journal of Neuroscience, 2008
The initial synapse in the olfactory system is from olfactory nerve (ON) terminals to postsynaptic targets in olfactory bulb glomeruli. Recent studies have disclosed multiple presynaptic factors that regulate this important linkage, but less is known ...

A Mathematical Model of a Neuron with Synapses based on Physiology [PDF]

, 2008
The neuron, when considered as a signal processing device, itsinputs are the frequency of pulses received at the synapses, and its output is the frequency of action potentials generated- in essence, a neuron is a pulse frequency signal processing device.
