Optoelectronic Synaptic Devices Using Molecular Telluride Phase‐Change Inks for Three‐Factor Learning

Advanced Functional Materials, EarlyView.
Optoelectronic synaptic devices based on solution‐processed molecular telluride GST‐225 phase‐change inks are demonstrated for three‐factor learning. A global optical signal broadcast through a silicon waveguide induces non‐volatile conductance updates exclusively in locally electrically flagged memristors.

Regulation of synaptic connectivity: levels of fasciclin II influence synaptic growth in the Drosophila CNS [PDF]

, 2002
Much of our understanding of synaptogenesis comes from studies that deal with the development of the neuromuscular junction (NMJ). Although well studied, it is not clear how far the NMJ represents an adequate model for the formation of synapses within ...

Synaptic state matching: a dynamical architecture for predictive internal representation and feature perception [PDF]

, 2011
Here we consider the possibility that a fundamental function of sensory cortex is the generation of an internal simulation of sensory environment in real-time.

Optical Bio-Inspired Synaptic Devices

Nanomaterials
The traditional computer with von Neumann architecture has the characteristics of separate storage and computing units, which leads to sizeable time and energy consumption in the process of data transmission, which is also the famous “von Neumann storage wall” problem.

Feedforward inhibition and synaptic scaling - two sides of the same coin? [PDF]

, 2012
Feedforward inhibition and synaptic scaling are important adaptive processes that control the total input a neuron can receive from its afferents. While often studied in isolation, the two have been reported to co-occur in various brain regions.

Neuromuscular synaptic transmission in aged ganglioside-deficient mice [PDF]

, 2011
Gangliosides are sialylated glycosphingolipids that are present in high density on neuronal membranes, especially at synapses, where they are assumed to play functional or modulating roles.
