In this paper, we apply a consensus model to decision-making in committees that have to choose one or more alternatives from a set of alternatives. Decision makers may be advised to adjust their preferences in order to obtain a better consensus. A simple example is presented.

With these services they have reduced poverty, and m...

Plamondon & Alimi (P&A) have unified much data on speed/accuracy trade-offs during reaching movements using a deltalognormal form factor that describes “the asymptotic behavior of a large number of dependent linear systems,” notably neuromuscular systems. Their approach raises questions about whether a large number of systems is needed, whether they are linear, and whether the results disclose ...

p0010 According to a long standing idea, reaching movements are supported by the dorsomedial parietofrontal circuit consisting of the superior parietal lobule (SPL) and the dorsal premotor cortex (PMd), whereas grasping movements entail the dorsolateral parietofrontal network involving the inferior parietal lobule (IPL) and the ventral premotor cortex (PMv). Recently, however, this dichotomist ...

Background: We consider the problem of identifying the dynamic interactions in biochemical networks from noisy experimental data. Typically, approaches for solving this problem make use of an estimation algorithm such as the well-known linear Least-Squares (LS) estimation technique. We demonstrate that when time-series measurements are corrupted by white noise and/or drift noise, more accurate ...

The exact function of motor cortex continues to be an enigma. In this issue of Neuron, present provocative data showing that microstimulation of the precentral cortex evokes complex movements, and conclude that the motor and premotor cortex together may form a single map of complex postures.

ErbB1 receptors situated on cellular filopodia undergo systematic retrograde transport after binding of the epidermal growth factor (EGF) and activation of the receptor tyrosine kinase. Specific inhibitors of the erbB1 receptor tyrosine kinase as well as cytochalasin D, a disruptor of the actin cytoskeleton, abolish transport but not free diffusion of the receptor-ligand complex. Diffusion cons...
