Cortical activity in the EEG alpha band has proven to be particularly sensitive to creativity-related demands, but its functional meaning in the context of creative cognition has not been clarified yet. Specifically, increases in alpha activity (i.e., alpha synchronisation) in response to creative thinking can be interpreted in different ways: As a functional correlate of cortical idling, as a ...

We use a neural mass model to address some important issues in characterising functional integration among remote cortical areas using magnetoencephalography or electroencephalography (MEG or EEG). In a previous paper [Neuroimage (in press)], we showed how the coupling among cortical areas can modulate the MEG or EEG spectrum and synchronise oscillatory dynamics. In this work, we exploit the mo...

The aim of present study was to investigate the effects of Ovsynch synchronisation programme combined with vitamins and minerals upon biochemical, hormonal and reproductive parameters for improving post partum (pp) reproductive performance of underfed dairy cows. Thirty-six healthy cows, aged 3-10 years-old, were used with a minimum 43 days pp. Following the first blood sampling (as baseline), ...

INTRODUCTION The EEG recorded during MRI inside the scanner is obstructed by the all but inevitable MRI gradient artefact (MGA) originating from the electromagnetic interference of the two measurements. Post-processing algorithms based on average artefact subtraction (AAS) have proven to be instrumental and efficient in removing the MGA [1-3]. However, the residual MGA after AAS still limits th...

Synchrony is claimed by psychology as a crucial parameter of any social interaction. In dialog interactions, the synchrony between non-verbal behaviours of interactants is claimed to account for the quality of the interaction: to give to human a feeling of natural interaction, an agent must be able to synchronise on appropriate time. The synchronisation occurring during non-verbal iteractions h...

This work introduces the phenomenon of Collective Almost Synchronisation (CAS), which describes a universal way of how patterns can appear in complex networks for small coupling strengths. The CAS phenomenon appears due to the existence of an approximately constant local mean field and is characterised by having nodes with trajectories evolving around periodic stable orbits. Common notion based...

The problem of modelling and synchronisation of multimedia objects is addressed in the declarative logic programming setting and in particular within the framework of (objectoriented) timed concurrent constraint programming (OO-TCCP). The real-time extensions that have been proposed for the concurrent constraint programming framework are coupled with the object-oriented and inheritance mechanis...

Pathological synchronisation of beta frequency (12-35Hz) oscillations between the subthalamic nucleus (STN) and cerebral cortex is thought to contribute to motor impairment in Parkinson's disease (PD). For this cortico-subthalamic oscillatory drive to be mechanistically important, it must influence the firing of STN neurons and, consequently, their downstream targets. Here, we examined the dyna...

Parallel programs running on shared memory multiprocessors coordinate via shared data objects/structures. To ensure the consistency of the shared data structures, programs typically rely on some forms of software synchronisations. Unfortunately typical software synchronisation mechanisms usually result in poor performance because they produce large amounts of memory and interconnection network ...

The bulk-synchronous parallel (BSP) model of computing has been proposed to enable the development of portable software which achieves scalable performance across diverse parallel architectures. A number of applications of computing science have been demonstrated to be e ciently supported by the BSP model in practice. In this thesis we study the e cient realisation of parallel discrete-event si...
