Neuronal action potentials or spikes provide a long-range, noise-resistant means of communication between neurons. As point processes single spikes contain little information in themselves, i.e., outside the context of spikes from other neu...
Modulation of Spike-Timing Dependent Plasticity: Towards the Inclusion of a Third Factor in Computational Models [0.03%]
基于时间的可塑性的调控：在计算模型中纳入第三个因素的影响

Alexandre Foncelle et al.
In spike-timing dependent plasticity (STDP) change in synaptic strength depends on the timing of pre- vs. postsynaptic spiking activity. Since STDP is in compliance with Hebb's postulate, it is considered one of the major mechanisms of memo...
The Dynamics of Balanced Spiking Neuronal Networks Under Poisson Drive Is Not Chaotic [0.03%]

Qing-Long L Gu et al.
Some previous studies have shown that chaotic dynamics in the balanced state, i.e., one with balanced excitatory and inhibitory inputs into cortical neurons, is the underlying mechanism for the irregularity of neural activity. In this work,...
