BACKGROUND Heterozygous paired box6 (Pax6) mutations lead to abnormal glucose metabolism in mice older than 6 months as well as in human beings. Our previous study found that Pax6 deficiency caused down-expression of prohormone convertase 1/3 (Pcsk1), resulting in defective proinsulin processing. As a protein cleaving enzyme, in addition to its expression, the activity of PC1/3 is closely relat...
INTRODUCTION Emotional stimulus is processed automatically in a bottom-up way or can be processed voluntarily in a top-down way. Imaging studies have indicated that bottom-up and top-down processing are mediated through different neural systems. However, temporal differentiation of top-down versus bottom-up processing of facial emotional expressions has remained to be clarified. The present stu...
A bunch-by-bunch feedback scheme is studied for damping coupled bunch synchmtron oscillations in the proposed PEP11 B Factory. The quasi-linear feedback system design incorporates a phase detector to provide aquantized measure of bunch phase, digital signal processing to compute an error correction signal and a kicker system to correct the energy of the bunches. A farm -of digital processors, o...
Dehaene, Changeux, Naccache, Sackur, and Sergent (2006) and Koch and Tsuchiya (2007) recently proposed taxonomies that distinguish between four processing states, based on bottom-up stimulus strength and top-down attentional amplification. The aim of the present study was to empirically test these processing states using the priming paradigm. Our results showed that attention (prime attended or...
