Recent neurophysiologic findings have shown that astrocytes play important roles in information processing and modulation of neuronal activity. Motivated by these findings, in the present research, a digital neuromorphic circuit to study neuron-astrocyte interaction is proposed. In this digital circuit, the firing dynamics of the neuron is described by(More)
Recent neurophysiologic findings have shown that astrocytes (the most abundant type of glial cells) are active partners in neural information processing and regulate the synaptic transmission dynamically. Motivated by these findings, in the present research, a digital neuromorphic circuit to implement the astrocyte dynamics is developed. To model the(More)
In this paper we propose a hardware implementation of a new deep brain stimulator that is able to desynchronize an abnormally synchronized neural population model. The proposed stimulator is based on a delay feedback technique and is applied on a population of neurons described with Izhikevich model. The whole structure of the stimulator and the neural(More)
