DOI: 10.1002/adma.202411237

Abstract: The limitations of deep neural networks in continuous learning stem from oversimplifying the complexities of biological neural circuits, often neglecting the dynamic balance between memory stability and learning plasticity. In this study, artificial synaptic devices… read more here.

DOI: 10.1016/j.nlm.2018.02.018

Abstract: HIGHLIGHTSReconsolidation—memory malleability after retrieval—does not occur invariably.Several factors affect a memory’s sensitivity to destabilization after retrieval.Experience‐driven changes in synaptic plasticity processes resemble metaplasticity.NMDAR receptors initiate bidirectional plasticity and also memory destabilization.The ratio of GluN2A:GluN2B NMDAR… read more here.

DOI: 10.1088/1361-6463/ae1405

Abstract: A solution-processed polymer thin film memristor is developed and utilized as a lateral electronic synapse. Such an organic synaptic device can progressively modulate its lateral conductance in response to afferent voltage pulses, based on the… read more here.
