Synchronization-based Parameter Estimation of Neuronal Networks
We study automated parameter searches on single neurons and two cell networks. In order to get round the effects of unknown initial conditions we focus on methods that are based on synchronization of the dynamical system to observed time series. The parameters are estimated with a slow dynamic equation that converges to the best value of the parameter. As this implementation does not require re...
متن کاملAutapses
So what are autapses good for? For many years, autapses in the brain had seemed like anatomical curiosities of unknown practical utility. Quite recently, however, experiments have begun to expose ways in which autapses might play subtle, but important, roles in brain function. One kind of experiment suggests that autaptic selfinhibition might act like a pendulum in a clock, maintaining the prec...
متن کاملElectric field modulation of synchronization in neuronal networks
Motivated by the observation that applied electric !elds modulate hippocampal seizures, and that seizures may be asynchronous, we modeled synaptically coupled two-compartment hippocampal pyramidal neurons embedded within an electrically resistive lattice in order to examine network synchronization properties under the in4uence of externally applied electric !elds. Excitatory electric !elds were...
متن کاملSpecial Session 1: Oscillations and Synchronization in Neuronal Networks
We show that the regulation of bursting activity in cells forming networks with mixed, inhibitory and excitatory fast chemical synapses is a crucial skill for controlling rhythmic movements in motifs, which are the building blocks of central pattern generators governing various motor behaviors. We have found that an order or bifurcation parameter controlling the network is the ratio of the burs...
متن کاملEmergence of local synchronization in neuronal networks with adaptive couplings
Local synchronization, both prolonged and transient, of oscillatory neuronal behavior in cortical networks plays a fundamental role in many aspects of perception and cognition. Here we study networks of Hindmarsh-Rose neurons with a new type of adaptive coupling, and show that these networks naturally produce both permanent and transient synchronization of local clusters of neurons. These deter...
