Model Cortical Association Fields Account for the Time Course and Dependence on Target Complexity of Human Contour Perception
Vadas Gintautas, Michael I. Ham, Benjamin Kunsberg +7
Can lateral connectivity in the primary visual cortex account for the time dependence and intrinsic task difficulty of human contour detection? To answer this question, we created…
Spontaneous coordinated activity in cultured networks: Analysis of multiple ignition sites, primary circuits, burst phase delay distributions and functional structures
Michael I. Ham, Vadas Gintautas, Guenter W. Gross
All higher order central nervous systems exhibit spontaneous neural activity, though the purpose and mechanistic origin of such activity remains poorly understood. We explore the i…
A Boundary Approximation Algorithm for Distributed Sensor Networks
Michael I. Ham, Marko A. Rodriguez
We present an algorithm for boundary approximation in locally-linked sensor networks that communicate with a remote monitoring station. Delaunay triangulations and Voronoi diagrams…
Density-dependence of functional development in spiking cortical networks grown in vitro
Michael I. Ham, Vadas Gintautas, Marko A. Rodriguez +3
During development, the mammalian brain differentiates into specialized regions with distinct functional abilities. While many factors contribute to functional specialization, we e…
Identification of functional information subgraphs in complex networks
Luis M. A. Bettencourt, Vadas Gintautas, Michael I. Ham
We present a general information theoretic approach for identifying functional subgraphs in complex networks where the dynamics of each node are observable. We show that the uncert…
The functional structure of cortical neuronal networks grown in vitro
Luis M. A. Bettencourt, Greg J. Stephens, Michael I. Ham +1
We apply an information theoretic treatment of action potential time series measured with microelectrode arrays to estimate the connectivity of mammalian neuronal cell assemblies g…
