TL;DR
In a network of neuronal oscillators with time-delayed coupling, a phenomenon of enhancement of neural synchrony by time delay is uncovered: a stable synchronized state exists at low coupling strengths for significant time delays.
Abstract
In a network of neuronal oscillators with time-delayed coupling, we uncover a phenomenon of enhancement of neural synchrony by time delay: a stable synchronized state exists at low coupling strengths for significant time delays. By formulating a master stability equation for time-delayed networks of Hindmarsh-Rose neurons, we show that there is always an extended region of stable synchronous activity corresponding to low coupling strengths. Such synchrony could be achieved in the undelayed system only by much higher coupling strengths. This phenomenon of enhanced neural synchrony by delay has important implications, in particular, in understanding synchronization of distant neurons and information processing in the brain.

It is demonstrated here that neurons in spatially separate columns can synchronize their oscillatory responses, which has, on average, no phase difference, depends on the spatial separation and the orientation preference of the cells and is influenced by global stimulus properties.

This work assumes that the coherence of SE-resonances is mediated by recurrent excitatory intra- and inter-areal connections via phase locking between assemblies that represent the linking features of the actual visual scene.

The equations, which were initially developed to explain isolated triggered bursts, provide one of the simplest models of the more general phenomenon of oscillatory burst discharge.

It is found that another measure, gamma-band coherence, increases between regions of the brain that receive the two classes of stimuli involved in an associative-learning procedure in humans, which could fulfil the criteria required for the formation of hebbian cell assemblies.

The second-order Fitzhugh equations are generalized, and the form of the functions in the new equations based on voltage-clamp data obtained from a snail neurone are based on, providing a model which predicts the linearity of the frequency–current relationship and may be useful for studying detailed interactions in networks containing small numbers of neurones.

Experimental observations of time-delay-induced amplitude death in two coupled nonlinear electronic circuits that are individually capable of exhibiting limit-cycle oscillations are described and the existence of multiply connected death islands in the parameter space of coupling strength and time delay for coupled identical oscillators is established.

Trial-to-trial amplitude variability of miniature calcium transients mediated by NMDARs increased with the injection of exogenous calcium buffers, suggesting that the amplitude of synaptic calciumTransients are maintained at a rather constant level by a calcium-mediated feedback mechanism.

It is shown in human intracranial recordings that limited regions of extrastriate visual areas, separated by several centimeters, become synchronized in an oscillatory mode during the rehearsal of an object in visual short-term memory.

Bifurcation theory is used to discuss the role that symmetry plays in determining the form and the stability of these oscillations, and it is found that arbitrarily large, dc-biased, arrays of Josephson junctions will phase lock most strongly when the capacitance parameter ${\ensuremath{\beta}}_{c}$1 and the bias current is about the same as the critical current of the individual junctions.

It is shown that for a finite delay time there exists a multitude of synchronized solutions in contrast to the situation without delay where one has at most one solution.

It is emphasized that the conscious function of the brain is neither epiphenomenal nor delayed, but operates transiently to integrate relevant perceptual features at the time of target object identification and of conscious behavioural decision.

Both experimental and theoretical approaches showed that rich oscillation phenomena between the two-coupled oscillators, namely, desynchronizing and antiphase/in-phase synchronization, are closely related to the time delay effect in interactions between the oscillators.
