    "title": "Incorporating Real-Time Rando m Time Effects in Neural Networks: A Temporal Summation Mechanism",
    "subtitle": null,
    "abstract": "Implementing random time effects in neural networks has \nbeen a challenge for neural network researchers. In this \npaper, we propose a neurophysiologically inspired temporal \nsummation mechanism to reflect real-time random dynamic \nprocessing in neural networks. According to the physiology \nof neuronal firing, a presynaptic neuron sends out a burst of \nrandom spikes to a postsynaptic neuron. In the postsynaptic \nneuron, spikes arriving at different points in time are summed \nuntil the postsynaptic membrane potential exceeds a \nthreshold, thus initiating postsynaptic firing. This temporal \nsummation process can be used as a metric for deriving time \npredictions in neural networks. To demonstrate potential \napplications of temporal summation, we have employed a \nfeedforward, two-layer network featuring a Hebbian learning \nrule to perform simulations using the semantic priming \nexperimental paradigm. W e are able to successfully \nreproduce not only the basic patterns of observed response \ntime data (e.g., positively skewed response time distributions \nand speed-accuracy trade-offs) but also the semantic priming \neffect and the time-course of priming as a function of \nstimulus-onset-asynchrony. These results suggest that the \nproposed temporal summation mechanism may be a \npromising candidate for incorporating real-time, random time \neffects into neural network modeling of human cognition.",
