Neuron Dynamics of Single-Compartment Traub Model for Hardware Implementations
In this work we make a bifurcation analysis for a single compartment representation of Traub model, one of the most important conductance-based models. The analysis focus in two principal parameters: current and leakage conductance. Study of stable and unstable solutions are explored; also Hop-bifurcation and frequency interpretation when current varies is examined. This study allows having con...
متن کاملGamma-oscillations Support Optimal Retrieval in Associative Memories of Pinsky-rinzel Neurons
Theoretical studies concerning iterative retrieval in conventional associative memories suggest that cortical gamma-oscillations may constitute sequences of fast associative processes each restricted to a single period. By providing a rhythmic threshold suppressing cells uncorrelated with a stimulus, interneurons signiiciantly contribute to this process. This hypothesis is tested in the present...
متن کاملAnalysis of complex bursting in cortical pyramidal neuron models
Burst "ring is a prominent feature of cortical pyramidal cells and is thought to have signi"cant functional roles in reliable signaling and synaptic plasticity. Modeling studies have successfully elucidated possible biophysical mechanisms underlying complex bursting in pyramidal cells. Based on these results (Pinsky, Rinzel, J. Comput. Neurosci. 1 (1994) 39}60), we have built a simpli"ed two-co...
متن کاملImpact of Geometrical StructuresOn the Output
What is the diierence between the eeerent spike train of a neuron with a large soma versus that of a neuron with a small soma? For both the two-compartment integrate-and-re (IF) model and the Pinsky-Rinzel (PR) model, we use a method we call the decoupling approach, to show that the smaller the soma is, the faster and the more irregularly the neuron res. Two limiting cases: the soma is much sma...
