This study considers the possibility of using coherence analysis for detection and measurement of synchrony (correlations) in large neural populations, applied to activities that are relatively easy to record in parallel. Mathematical analysis and computer simulations are used to examine the behavior of the coherence function between both unitary and population-aggregate activity (UTA coherence...

We outline two improvements to the technique of gravitational clustering for detection of neuronal synchrony, which are capable of improving the method's detection of weak synchrony with limited data. The advantages of the enhancements are illustrated using data with known levels of synchrony and different interspike interval distributions. The novel simulation method described can easily gener...

Music and dance appear to have a social bonding effect, which some theorized is part of their ultimate evolutionary function. Prior research has also found effect synchronized movement, it possible that interpersonal synchrony could be considered the “active ingredient” in consequences music or activity. The present study aimed separate effects from other factors associated with joint experienc...

In this paper, we propose a new framework to assess temporal coordination (synchrony) and content coordination (behavior matching) in dyadic interaction. The synchrony module is dedicated to identify the time lag and possible rhythm between partners. The imitation module aims at assessing the distance between two gestures, based on 1-Class SVM models. These measures discriminate significantly c...

We apply an information-theoretic measure for phase synchrony to local field potentials (LFPs) [corrected] recorded with a multi-electrode array implanted in area V4 of the monkey visual cortex. We show for the first time statistically significant stimulus-dependent synchrony of the visual cortical LFPs and this during different, short time intervals of the response. Furthermore, we could compu...

Many different biological systems experience mutual synchrony [2]. We have studied the particular case of synchrony amongst two crickets using an adapted integrate and fire model studied by Mirollo and Strogatz. By using a microphone and speaker coupling to model a cricket, we tested to see if the crickets would synchronize. I found conclusive data for mutual synchrony when running numerical si...

Sound and complete axiomatizations are provided for two different logics involving modalities for knowledge and both past and future time modalities. The logics considered allow for multiple agents with unique initial state and synchrony. The synchrony restriction gives every agent access to a system clock. Such semantic restrictions are of particular interest in the context of past time modali...

Activity in the mammalian thalamocortical system is often accompanied by a synchronous discharge of cortical and thalamic neurons. Although many functions have been attributed to such synchronous firing, it is not known whether or how synchrony of firing per se affects thalamocortical operations. Direct experimental tests of the consequences of neuronal synchronization in vivo are hard to carry...
