EURASIP Journal on Applied Signal Processing 2003:7, 620–628 c 2003 Hindawi Publishing Corporation Analog VLSI Circuits for Short-Term Dynamic Synapses Shih-Chii Liu Institute of Neuroinformatics, University of Zurich and ETH Zurich, Winterthurerstrasse 190, CH-8057 Zurich, Switzerland Email: shih@ini.phys.ethz.ch Received 14 May 2002 and in revised form 25 September 2002 Short-term dynamical synapses increase the computational power of neuronal networks. These synapses act as additional ﬁlters to the inputs of a neuron before the subsequent integration of these signals at its cell body. In this work, we describe a model of depressing and facilitating synapses derived from a hardware circuit implementation. This model is...
