Simple Cortical and Thalamic Neuron Models for Digital Arithmetic Circuit Implementation

Trade-off between reproducibility of neuronal activities and computational efficiency is one of crucial subjects in computational neuroscience and neuromorphic engineering. A wide variety of neuronal models have been studied from different viewpoints. The digital spiking silicon neuron (DSSN) model is a qualitative model that focuses on efficient implementation by digital arithmetic circuits. W...

Analysis and Implementation of CMOS based Analog Circuit of Cortical Neuron

This paper presents analysis and simulation of a CMOS based cortical neuron circuit at 0.25μm technology node. The spiking and bursting patterns generated after the simulation of the circuit are studied. Also, the effect of variation of the (W/L) ratios of transistors on the spiking pattern is analyzed in this paper. The results obtained by simulation and the variations in parameters shows that...

Stochastic Resonance in Thalamic Neurons and Resonant Neuron Models

Neurons of the thalamus are major participants in gating sensory information for relay to the neocortex. Thalamic neurons are crucially involved in rhythmogenesis which determines the sleep/wake cycle. These roles require critical involvement of a T-type calcium current, conferring a frequency preference in response to subthreshold signals. We examine the interactions of this membrane resonance...
