Shaping Synapses by the Neural Extracellular Matrix

open access: yesFrontiers in Neuroanatomy, 2018
Accumulating data support the importance of interactions between pre- and postsynaptic neuronal elements with astroglial processes and extracellular matrix (ECM) for formation and plasticity of chemical synapses, and thus validate the concept of a ...

Frequency Switching Neuristor for Realizing Intrinsic Plasticity and Enabling Robust Neuromorphic Computing

open access: yesAdvanced Materials, EarlyView.
A frequency switching (FS) neuristor is proposed, comprising a Mott memristor and a valence change mechanism (VCM) memristor. The FS neuristor exhibits a multi‐level frequency–voltage (f–V) characteristics, enabling the implementation of neuronal intrinsic plasticity transfer functions.

Revisiting Ferroelectric‐Gated Phototransistors: A Tripartite Synapse‐Inspired Approach to In‐Sensor Image Processing

open access: yesAdvanced Materials, EarlyView.
A ferroelectric‐gated phototransistor (FGPT) enables linear and multilevel modulation of photoconductance through partial polarization switching and photogating effects. The device achieves photonic non‐volatility over a 153 dB dynamic range and performs in‐sensor processing under unstructured illumination, demonstrating enhanced face recognition ...

Ferroelectric Quantum Dots for Retinomorphic In‐Sensor Computing

open access: yesAdvanced 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 ...

Deconstructing the synapse

open access: yesNature Neuroscience, 2018
While the role of protein synthesis in synaptic plasticity and memory is well-established, protein degradation processes have been less studied. A seminal 2003 Nature Neuroscience paper showed that ubiquitin-dependent degradation of synaptic proteins is engaged during activity-regulated synaptic remodeling.
