Effects of synaptic integration on the dynamics and computational performance of spiking neural network

摘要

External currents applied to neurons in the spiking neural network. a PSP kernel: solid line represents NMDA kernel, while dotted line represents AMPA kernel. b AMPA synaptic external current generated through a Poisson spike train (upper colored spikes) which is converted into dynamic synaptic inputs by AMPA kernel and then integrated by synaptic integration: dotted line represents the average value of current. c NMDA synaptic external current. d Noise external current (Gaussian noise is added to the static direct current).
