Residual Stresses and Micro‐voids Propel Metal Diffusion for Filament‐Based Memristors

Advanced Science, EarlyView.
Introducing non‐reactive nitrogen during silver sputtering enables low‐voltage (<60 mV) switching in memristors via nano‐void formation and residual stresses in the gigapascal range. This promotes sub‐micron filamentation and neuromorphic behaviors, including multi‐peak synaptic responses.

Tutorial: Neuromorphic spiking neural networks for temporal learning

, 2018
Spiking neural networks (SNN) as time-dependent hypotheses consisting of spiking nodes (neurons) and directed edges (synapses) are believed to offer unique solutions to reward prediction tasks and the related feedback that are classified as reinforcement

Inhibition of Cgkii Suppresses Seizure Activity and Hippocampal Excitation by Regulating the Postsynaptic Delivery of Glua1

Cellular Physiology and Biochemistry, 2018
Background/Aims: The imbalance between excitation and inhibition is a defining feature of epilepsy. GluA1 is an AMPA receptor subunit that can strengthen excitatory synaptic transmission when upregulated in the postsynaptic membrane, which has been ...

Heterointerface‐Modulated Synthetic Synapses Exhibiting Complex Multiscale Plasticity

Advanced Science, EarlyView.
An asymmetric dual‐gate heterointerface‐regulated artificial synapse (HRAS) is developed, employing distinct ion concentrations and dielectric coupling to form precise dual‐interface channels. Through lateral modulation, HRAS realizes, for the first time, the intricate interplay of lateral inhibition/enhancement and multi‐level short‐ and long‐term ...

Multifaceted Changes in Synaptic Composition and Astrocytic Involvement in a Mouse Model of Fragile X Syndrome. [PDF]

, 2019
Fragile X Syndrome (FXS), a common inheritable form of intellectual disability, is known to alter neocortical circuits. However, its impact on the diverse synapse types comprising these circuits, or on the involvement of astrocytes, is not well known. We

Pia Mater‐Penetrable Lipopolymer Nanoparticles for Gliocyte‐Targeted IL‐10 mRNA Therapy Alleviate Paclitaxel‐Induced Peripheral Neuropathy

Advanced Science, EarlyView.
The P6CIT lipopolymer demonstrates superior transfection efficacy in the spinal cord and DRG, as well as enhanced penetration of the pia mater compared to the MC3 ionizable lipid. Intrathecal delivery of P6CIT LPNPs enables effective transfection in the gliocytes in the spinal cord and DRG.

Connectivity reflects coding: A model of voltage-based spike-timing-dependent-plasticity with homeostasis [PDF]

, 2009
Electrophysiological connectivity patterns in cortex often show a few strong connections in a sea of weak connections. In some brain areas a large fraction of strong connections are bidirectional, in others they are mainly unidirectional.
