Role of Amorphous Phases in Mixed Conduction of Conjugated Regioblock Copolymers for Organic Electrochemical Synaptic Transistors

Advanced Materials, EarlyView.
Critical roles of amorphous and crystalline phases in polymer‐based mixed ionic‐electronic conductors for organic electrochemical synaptic transistors using conjugated regioregular‐block‐regiorandom copolymers are demonstrated. Amorphous phases contribute to gradual polaron formation and strong ion trapping by bipolarons, leading to improved synaptic ...

Quantitative Analysis Linking Inner Hair Cell Voltage Changes and Postsynaptic Conductance Change: A Modelling Study [PDF]

, 2015
This paper presents a computational model which estimates the postsynaptic conductance change of mammalian Type I afferent peripheral process when airborne acoustic waves impact on the tympanic membrane. A model of the human auditory periphery is used to

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

PSD95 nanoclusters are postsynaptic building blocks in hippocampus circuits

Scientific Reports, 2016
The molecular features of synapses in the hippocampus underpin current models of learning and cognition. Although synapse ultra-structural diversity has been described in the canonical hippocampal circuitry, our knowledge of sub-synaptic organisation of ...

Ferroelectric Quantum Dots for Retinomorphic In‐Sensor Computing

Advanced Materials, EarlyView.
This work has provided a protocol for fabricating retinomorphic phototransistors by integrating ferroelectric ligands with quantum dots. The resulting device combines ferroelectricity, optical responsiveness, and low‐power operation to enable adaptive signal amplification and high recognition accuracy under low‐light conditions, while supporting ...

Analysis of the intraspinal calcium dynamics and its implications on the plasticity of spiking neurons

, 2003
The influx of calcium ions into the dendritic spines through the N-metyl-D-aspartate (NMDA) channels is believed to be the primary trigger for various forms of synaptic plasticity.

Quantal components of the excitatory postsynaptic currents at a rat central auditory synapse [PDF]

The Journal of Physiology, 2001
1. Paired whole-cell recordings were made from a glutamatergic giant nerve terminal, the calyx of Held, and its postsynaptic target cell in the medial nucleus of the trapezoid body (MNTB) in the brainstem slice of juvenile rat. Excitatory postsynaptic currents (EPSCs) were evoked by presynaptic action potentials triggered by brief (1 ms) depolarizing ...

Additive Manufacturing of Neuromorphic Systems

Advanced Materials, EarlyView.
The crossover of additive Manufacturing (AM) and neuromorphic engineering promises a new paradigm in the fabrication of intelligent hardware—one that is sustainable, scalable, cost‐efficient, and customizable. The AM‐printed neuromorphic hardware (electronics and mechanical systems) is examined, and we discussed the technological integration.
