Synaptic metaplasticity with multi-level memristive devices

2023 IEEE 5th International Conference on Artificial Intelligence Circuits and Systems (AICAS), 2023
Deep learning has made remarkable progress in various tasks, surpassing human performance in some cases. However, one drawback of neural networks is catastrophic forgetting, where a network trained on one task forgets the solution when learning a new one.

Synaptic proteins as multi-sensor devices of neurotransmission [PDF]

BMC Neuroscience, 2006
Abstract Neuronal communication is tightly regulated in time and space. Following neuronal activation, an electrical signal triggers neurotransmitter (NT) release at the active zone. The process starts by the signal reaching the synapse followed by a fusion of the synaptic vesicle (SV) and diffusion of the released NT in the synaptic cleft ...

Recent progress on optoelectronic synaptic devices [PDF]

SCIENTIA SINICA Informationis, 2020
Neuromorphic (brain-like) computing has great potential to solve the von Neumann bottleneck due to its self-adaptive learning, high-parallel computing capability, and low-power consumption. Realization of neuromorphic computing depends on the development of synaptic devices that mimic biological synapses.

MSK1 regulates homeostatic and experience-dependent synaptic plasticity [PDF]

, 2012
The ability of neurons to modulate synaptic strength underpins synaptic plasticity, learning and memory, and adaptation to sensory experience. Despite the importance of synaptic adaptation in directing, reinforcing, and revising the behavioral response ...
