WebJun 1, 2006 · Abstract. In timing-based neural codes, neurons have to emit action potentials at precise moments in time. We use a supervised learning paradigm to derive a synaptic update rule that optimizes by gradient ascent the likelihood of postsynaptic firing at one or several desired firing times. We find that the optimal strategy of up- and downregulating … WebApr 13, 2024 · Efficient processing and transfer of information in neurons have been linked to noise-induced resonance phenomena such as coherence resonance (CR), and adaptive …
WebThese results provided evidence that neuronal firing synchrony has predictive power. To elucidate the underlying mechanism, here we argue some nontrivial characteristics of the predictive synchronous firing developed by spike-timing-dependent plasticity in a paradigm similar to classical conditioning.
WebSep 1, 2006 · From the point of view of pure spike timing-dependent plasticity, the instantaneous weight change is an unknown functional of the presynaptic spike train X and the postsynaptic spike train Y (i.e., dw/dt = H[X, Y]). In this framework, a pair-based STDP learning rule corresponds to the Volterra expansion of H to the second order. In this paper ... coping skills for disappointmentsWebSep 30, 2004 · Abstract.
