In vivo mapping of functional domains and axonal connectivity in cat visual cortex using magnetic resonance imaging 总被引:5,自引:0,他引:5

Noninvasive cognitive neuroimaging studies based on functional magnetic resonance imaging (fMRI) are of ever-increasing importance for basic and clinical neurosciences. The explanatory power of fMRI could be greatly expanded, however, if the pattern of the neuronal circuitry underlying functional activation could be made visible in an equally noninvasive manner. In this study, blood oxygenation level-dependent (BOLD)-based fMRI and diffusion tensor imaging (DTI) were performed in the same cat visual cortex, and the foci of fMRI activation utilized as seeding points for 3D DTI fiber reconstruction algorithms, thus providing the map of the axonal circuitry underlying visual information processing. The methods developed in this study will lay the foundation for in vivo neuroanatomy and the ability for noninvasive longitudinal studies of brain development. 相似文献

Two novel dithiophosphonate ligands, HS2P(p‐C6H4OMe)(OCH2CH2CH(CH3)2) ( 1 ) and HS2P(p‐C6H4OMe)(OCH(CH3)2) ( 2 ), were synthesized and characterized by multinuclear (1H, 31P, and 13C) NMR, infrared spectroscopy as well as elemental analysis. The reactions of 1 and 2 with NiCl2·6H2O and Cd(NO3)2·4H2O in methanol led to novel complexes 3 and 4 . The single crystal X‐ray structures of 3 and 4 showed tetracoordinated structure with square planar geometry for the nickel complex, while it showed pentacoordinated structure with distorted square‐pyramid environment for the cadmium complex. 相似文献

New Group 3 metal complexes of the type [LM(CH2SiMe3)2(THF)n] supported by tridentate phosphido‐diphosphine ligands [(o‐C6H4PR2) 2 PH; L1‐H : R = iPr; L2‐H : R = Ph] have been synthesized by reaction of L1‐H and L2‐H with [M(CH2SiMe3)3(THF)2)] (M = Y and Sc). All the new complexes [(o‐C6H4PR2) 2 PM(CH2SiMe3)2(THF)n] [M = Y, R = iPr (1), R = Ph (2); M = Sc, R = iPr (3), R = Ph (4)] were studied as initiators for the ring opening polymerization of lactide. The yttrium complexes ( 1 and 2 ) exhibited high activity and good polymerization control, shown by the linear fits in the plot of number‐averaged molecular weight (Mn) versus the percentage conversion and versus the monomer/initiator ratio and by the low polydispersity index values. Interestingly, very good molar‐mass control was observed even when L ‐Lactide was polymerized in the absence of solvent at 130 °C. A good molar‐mass control but lower activities were observed in the polymerization reaction of lactide promoted by the analogous scandium complexes 3 and 4 . © 2010 Wiley Periodicals, Inc.

This paper discusses the issue of how to use fuzzy targets in the target-based model for decision making under uncertainty.
After introducing a target-based interpretation of the expected value on which it is shown that this model implicitly assumes
a neutral behavior on attitude about the target, we examine the issue of using fuzzy targets considering different attitudes
about the target selection of the decision maker. We also discuss the problem for situations on which the decision maker’s
attitude about target may change according to different states of nature. Especially, it is shown that the target-based approach
can provide an unified way for solving the problem of fuzzy decision making with uncertainty about the state of nature and
imprecision about payoffs. Several numerical examples are given for illustration of the discussed issues. 相似文献
