Controlling Effects of Astrocyte on Neuron Behavior in Tripartite Synapse Using VHDL–AMS

Astrocyte cells form the largest cell population in brain and can influence neuron behavior. These provide appropriate feedback control regulating neuronal activities Central Nervous System (CNS). This paper presents a set of equations as model to describe interactions between neurons astrocyte. A VHDL–AMS-based tripartite synapse that includes pre-synaptic neuron, synaptic terminal, post-synaptic an astrocyte is presented. In this model, acts controller module for regulates spiking activity them. Simulation results show by coupling coefficients astrocytes, frequency be reduced modulated.
