Inhibition in Random Neuronal Networks Enhances Response Variability and Disrupts Stimulus Discrimination
Netta Haroush, Shimon Marom
Inhibition is considered to shape neural activity, and broaden its pattern repertoire. In the sensory organs, where the anatomy of neural circuits is highly structured, lateral inh…
Cellular function given parametric variation: excitability in the Hodgkin-Huxley model
Hillel Ori, Eve Marder, Shimon Marom
How is reliable physiological function maintained in cells despite considerable variability in the values of key parameters of multiple interacting processes that govern that funct…
Visual detection of time-varying signals: opposing biases and their timescales
Urit Gordon, Shimon Marom, Naama Brenner
Human visual perception is a complex, dynamic and fluctuating process. In addition to the incoming visual stimulus, it is affected by many other factors including temporal context,…
Closed-loop control of a modular neuromorphic biohybrid
Hanna Keren, Johannes Partzsch, Shimon Marom +1
Neural networks modularity is a major challenge for the development of control circuits of neural activity. Under physiological limitations, the accessible regions for external sti…
Emergence and Maintenance of Excitability: Kinetics over Structure
Shimon Marom
Emergence and maintenance of excitability is often phrased in terms of arriving at and remaining about a manifold of 'solutions' embedded in a high dimensional parameter space. Alo…
Long-range synchrony and emergence of reentry in neural networks
Hanna Keren, Shimon Marom
Synchronization across long neural distances is a functionally important phenomenon. In order to access the mechanistic basis of long-range synchrony, we constructed an experimenta…
Network events on multiple space and time scales in cultured neural networks and in a stochastic rate model
Guido Gigante, Gustavo Deco, Shimon Marom +1
Cortical networks, in-vitro as well as in-vivo, can spontaneously generate a variety of collective dynamical events such as network spikes, UP and DOWN states, global oscillations,…
Evidence for Dynamic Excitation-Inhibition Ratio in Networks of Cortical Neurons
Netta Haroush, Shimon Marom
In this report trial-to-trial variations in the synchronized responses of neural networks are offered as evidence for excitation-inhibition ratio being a dynamic variable over time…
Entrainment of the intrinsic dynamics of single isolated neurons by natural-like input
Asaf Gal, Shimon Marom
Neuronal dynamics is intrinsically unstable, producing activity fluctuations that are essentially scale-free. Here we show that while these scale-free fluctuations are independent…
Self-organized criticality in single neuron excitability
Asaf Gal, Shimon Marom
We present experimental and theoretical arguments, at the single neuron level, suggesting that neuronal response fluctuations reflect a process that positions the neuron near a tra…
Synchronization with mismatched synaptic delays: A unique role of elastic neuronal latency
Roni Vardi, Reut Timor, Shimon Marom +2
We show that the unavoidable increase in neuronal response latency to ongoing stimulation serves as a nonuniform gradual stretching of neuronal circuit delay loops and emerges as a…
Synthetic reverberating activity patterns embedded in networks of cortical neurons
Roni Vardi, Avner Wallach, Evi Kopelowitz +3
Synthetic reverberating activity patterns are experimentally generated by stimulation of a subset of neurons embedded in a spontaneously active network of cortical cells in-vitro.…
Neuronal Response Clamp
Avner Wallach, Danny Eytan, Asaf Gal +3
Since the first recordings made of evoked action potentials it has become apparent that the responses of individual neurons to ongoing physiologically relevant input, are highly va…
Leadership in 2D living neural networks
Jean-Pierre Eckmann, Shimshon Jacobi, Shimon Marom +2
Eytan and Marom recently showed that the spontaneous burst activity of rat neuron cultures includes `first to fire' cells that consistently fire earlier than others. Here we analyz…
