- Generation of Functional Ventricular Heart Muscle from Mouse Ventricular Progenitor Cells
[作者:Domian, IJ; Chiravuri, M; van der Meer, P; Feinberg, AW; Shi, X; Shao, Y; Wu, SM; Parker, KK; Chien, KR,期刊:Science, 页码:426-429 , 文章类型: Article,,卷期:2009年326-5951]
- The mammalian heart is formed from distinct sets of first and second heart field (FHF and SHF, respectively) progenitors. Although multipotent progenitors have previously been shown to give rise to cardiomyocytes, smooth...
- Tyrannosaurid Skeletal Design First Evolved at Small Body Size
[作者:Sereno, PC; Tan, L; Brusatte, SL; Kriegstein, HJ; Zhao, XJ; Cloward, K,期刊:Science, 页码:418-422 , 文章类型: Article,,卷期:2009年326-5951]
- Nearly all of the large-bodied predators (>2.5 tons) on northern continents during the Late Cretaceous were tyrannosaurid dinosaurs. We show that their most conspicuous functional specializations-a proportionately large ...
- Dirac Strings and Magnetic Monopoles in the Spin Ice Dy2Ti2O7
[作者:Morris, DJP; Tennant, DA; Grigera, SA; Klemke, B; Castelnovo, C; Moessner, R; Czternasty, C; Meissner, M; Rule, KC; Hoffmann, JU; Kiefer, K; Gerischer, S; Slobinsky, D; Perry, RS,期刊:Science, 页码:411-414 , 文章类型: Article,,卷期:2009年326-5951]
- Sources of magnetic fields-magnetic monopoles-have so far proven elusive as elementary particles. Condensed-matter physicists have recently proposed several scenarios of emergent quasiparticles resembling monopoles. A pa...
- Fast Synaptic Subcortical Control of Hippocampal Circuits
[作者:Varga, V; Losonczy, A; Zemelman, BV; Borhegyi, Z; Nyiri, G; Domonkos, A; Hangya, B; Holderith, N; Magee, JC; Freund, TF,期刊:Science, 页码:449-453 , 文章类型: Article,,卷期:2009年326-5951]
- Cortical information processing is under state-dependent control of subcortical neuromodulatory systems. Although this modulatory effect is thought to be mediated mainly by slow nonsynaptic metabotropic receptors, other ...
- Modalities, Modes, and Models in Functional Neuroimaging
[作者:Friston, KJ,期刊:Science, 页码:399-403 , 文章类型: Review,,卷期:2009年326-5951]
- In this, the 21st century, human-brain mapping celebrates 21 years of cognitive activation studies. This review looks at imaging neuroscience and key ideas it has pursued; some ideas portend exciting developments, and ot...
- The Optogenetic Catechism
[作者:Miesenbock, G,期刊:Science, 页码:395-399 , 文章类型: Review,,卷期:2009年326-5951]
- An emerging set of methods enables an experimental dialogue with biological systems composed of many interacting cell types-in particular, with neural circuits in the brain. These methods are sometimes called "optogeneti...
- Molecular and Cellular Approaches to Memory Allocation in Neural Circuits
[作者:Silva, AJ; Zhou, Y; Rogerson, T; Shobe, J; Balaji, J,期刊:Science, 页码:391-395 , 文章类型: Review,,卷期:2009年326-5951]
- Although memory allocation is a subject of active research in computer science, little is known about how the brain allocates information within neural circuits. There is an extensive literature on how specific types of ...
- The Packing of Granular Polymer Chains
[作者:Zou, LN; Cheng, X; Rivers, ML; Jaeger, HM; Nagel, SR,期刊:Science, 页码:408-410 , 文章类型: Article,,卷期:2009年326-5951]
- Rigid particles pack into structures, such as sand dunes on the beach, whose overall stability is determined by the average number of contacts between particles. However, when packing spatially extended objects with flex...
