Adaptive Latent Inhibition in Associatively Responsive Optoelectronic Synapse
Advanced Functional Materials, 2021 AbstractThe association of stimuli is an important attribute in the neural basis of learning and memory. While the acquisition and extinction of association through conditioning are well emulated in artificial synaptic devices, the alteration of conditioning efficacy, which enables adaptability in learning, has yet to be demonstrated.

Optoelectronic Synapses Based on Hot-Electron-Induced Chemical Processes [PDF]
Nano Letters, 2020 Highly efficient information processing in the brain is based on processing and memory components called synapses, whose output is dependent on the history of the signals passed through them. Here, we have developed an artificial synapse with both electrical and optical memory effects using chemical transformations in plasmonic tunnel junctions.
