LFP beta amplitude is predictive of mesoscopic spatio-temporal phase patterns

Beta oscillations observed in motor cortical local field potentials (LFPs) recorded on separate electrodes of a multi-electrode array have been shown to exhibit non-zero phase shifts that organize into a planar wave propagation. Here, we generalize this concept by introducing additional classes of patterns that fully describe the spatial organization of beta oscillations. During a delayed reach-to-grasp task in monkey primary motor and dorsal premotor cortices we distinguish planar, synchronized, random, circular, and radial phase patterns. We observe that specific patterns correlate with the beta amplitude (envelope). In particular, wave propagation accelerates with growing amplitude, and culminates at maximum amplitude in a synchronized pattern. Furthermore, the occurrence probability of a particular pattern is modulated with behavioral epochs: Planar waves and synchronized patterns are more present during movement preparation where beta amplitudes are large, whereas random phase patterns are dominant during movement execution where beta amplitudes are small

THE MACROECONOMIC IMPLICATIONS OF CONSUMPTION: STATE-OF-ART AND PROSPECTS FOR THE HETERODOX FUTURE RESEARCH

The recent US economic scenario has motivated a series of heterodox papers concerned with household indebtedness and consumption. Though discussing autonomous consumption, most of the theoretical papers rely on private investment-led growth models. An alternative approach is the so-called Sraffian supermultipler model, which treats long-run investment as induced, allowing for the possibility that other final demand components – including consumption – may lead long-run growth. We suggest that the dialogue between these approaches is not only possible but may prove to be quite fruitful.The recent US economic scenario has motivated a series of heterodox papers concerned with household indebtedness and consumption.

A Supermultiplier Stock-Flow Consistent model: the return of the paradoxes of thrift and costs in the long run?

Supermultiplier models have been recently brought to the post-Keynesian debate. Yet these models still rely on quite simple economic assumptions, being mostly ow models which omit the �nancial determinants of autonomous expenditures. Since the output growth rate converges in the long run to the exogenously given growth rate of \non-capacity creating" autonomous expenditure and the utilization rate moves towards the normal utilization rate, the paradoxes of thrift and costs remain valid only as level e�ects (average growth rates). This paper investigates whether the core conclusions of supermultiplier models hold in a more complex economic framework, described by means of a supermultiplier SFC model, in which private business investment is assumed to be completely induced by income while the autonomous expenditure component - in this case consumption out of wealth - becomes endogenous. The results of the numerical simulation experiments suggest that the paradox of thrift can remain valid in terms of growth e�ects and that a lower pro�t share can also be associated to a higher accumulation rate, though with a lower pro�t rate

Evaluation, contrôle et prévention du risque de transmission du virus influenza aviaire à l'homme

Since mid-december 2003, an epizootic of highly pathogenic avian influenza (type A, sub-type H5N1) occurs in eastern and south-eastern Asia. This epizootic is historically unprecedented in its virulence, geographical spread, and economic consequences for the agricultural sector. Implications for human health were registered in Vietnam and in Thailand. This paper summarizes the current knowledge about the risk evaluation of the transmission of avian influenza virus to humans. The current asian epizootic has highlighted the key role of global health information systems and also the need for exhaustive notification of human and animal cases. It reinforces the concept of veterinary public health
