Príncipe, “Modeling of synchronized burst in dissociated cortical tissue: An exploration of parameter space
- in IEEE International Joint Conference on Neural Networks
, 2006
"... Abstract — In vitro neuronal culture is a potentially powerful tool for investigation of information processing of neurons. However, in a mature dissociated neuronal culture, synchro-nized bursting is often observed. Bursting strongly drives the dynamics of the network, thus making it difficult to i ..."

Chaos and Synchrony in a Model of a Hypercolumn in Visual Cortex
- JOURNAL OF COMPUTATIONAL NEUROSCIENCE 3, 7-34 (1996)' @ 1996 KLUWER ACADEMIC PUBLISHERS. MANUFACTURED IN THE NETHERLANDS.
, 1996
"... Neurons in cortical slices emit spikes or bursts of spikes regularly in response to a suprathreshold current injection. This behavior is in marked contrast to the behavior of cortical neurons in vivo, whose response to electrical or sensory input displays a strong degree of irregularity. Correlation ..."

. Correlation measurements show a significant degree of synchrony in the temporal fluctuations of neuronal activities in cortex. We explore the hypothesis that these phenomena are the result of the synchronized chaos generated by the deterministic dynamics of local cortical networks. A model of a &
Growth Dynamics Explain the Development of Spatiotemporal Burst Activity of Young Cultured Neuronal Networks in Detail
"... A typical property of isolated cultured neuronal networks of dissociated rat cortical cells is synchronized spiking, called bursting, starting about one week after plating, when the dissociated cells have sufficiently sent out their neurites and formed enough synaptic connections. This paper is the ..."

RESEARCH ARTICLE Bursting Regimes in a Reaction-Diffusion System with Action Potential-Dependent Equilibrium
"... The equilibrium Nernst potential plays a critical role in neural cell dynamics. A common ap-proximation used in studying electrical dynamics of excitable cells is that the ionic concen-trations inside and outside the cell membranes act as charge reservoirs and remain effectively constant during exci ..."

with developing transmembrane potential. As a specific implementation, we incorporate the potential-dependent Nernst shift into a one-dimensional Morris-Lecar reaction-diffusion model. Our main findings result from a region in parameter space where self-sustaining oscillations occur without external forc-ing
Self-regulated homoclinic chaos in neural networks activity. 8th Experimental Chaos Conference
"... Abstract. We compare the recorded activity of cultured neuronal networks with hybridized model simulations, in which the model neurons are driven by the recorded activity of special neurons. The latter, named ’spiker ’ neurons, that exhibit fast firing with homoclinic chaos like characteristics, are ..."

by the formation of temporal sequences of synchronized bursting events (SBEs), and additional features which seemingly reflect the action of underlying regulating mechanism, rather than arbitrary causes and effects. Our model neurons are composed of soma described by the two Morris-Lecar dynamical variables
Spatial evolutionary games of interaction among generic cancer cells
- Computational and Mathematical Methods in Medicine 5
, 2003
"... Evolutionary game models of cellular interactions have shown that heterogeneity in the cellular genotypic composition is maintained through evolution to stable coexistence of growth-promoting and non-promoting cell types. We generalise these mean-field models and relax the assumption of perfect mix ..."
