Journal ArticleDOI
Self-sustained activity in a small-world network of excitable neurons.
TL;DR: The dynamics of excitable integrate-and-fire neurons in a small-world network is studied, finding thatceedingly long transients emerge at higher densities p; their activity patterns are disordered, in contrast to the mostly periodic persistent patterns observed at low p.
Journal ArticleDOI
Mechanisms of pattern decorrelation by recurrent neuronal circuits.
TL;DR: It is proved that pattern decorrelation emerges from neuronal nonlinearities and is amplified by recurrent connectivity and does not require adaptation of the network, is enhanced by sparse connectivity, depends on the baseline membrane potential and is robust.
Journal ArticleDOI
A Synaptic Mechanism for Retinal Adaptation to Luminance and Contrast
Tim Jarsky,Mark S. Cembrowski,Stephen M. Logan,William L. Kath,Hermann Riecke,Jonathan B. Demb,Joshua H. Singer +6 more
TL;DR: Electrophysiological and computational analyses demonstrated that adaptation to mean potential resulted from both Ca channel inactivation and vesicle depletion, whereas adaptation to variance resulted from vesicles depletion alone, suggesting background and contrast adaptation apparently depend in part on a common synaptic mechanism.
Journal ArticleDOI
Transitions between patterned states in vegetation models for semiarid ecosystems.
TL;DR: The robustness of this "standard" sequence of qualitatively different patterned states, "gaps → labyrinth → spots," is explored in the generic setting of a bifurcation problem on a hexagonal lattice, as well as in a particular reaction-diffusion model for vegetation pattern formation.
Journal ArticleDOI
Intrinsic bursting of AII amacrine cells underlies oscillations in the rd1 mouse retina
Hannah Choi,Lei Zhang,Mark S. Cembrowski,Carl Sabottke,Alexander L. Markowitz,Daniel A. Butts,William L. Kath,Joshua H. Singer,Hermann Riecke +8 more
TL;DR: It is concluded that oscillations are not an emergent property of a degenerated retinal network, rather, they arise largely from the intrinsic properties of a single retinal interneuron, the AII amacrine cell.
