    Comparisons among some tetraalkoxysilanes in the hydrolytic precipitation of silica into elastomeric networks (1986)
    New York : Wiley-Blackwell
    Die Makromolekulare Chemie 187 (1986), S. 2861-2866

    Topics: Chemistry and Pharmacology , Physics
    Notes: Four tetraalkoxysilanes Si(OR)4 were absorbed into networks of polydimethylsiloxane and then hydrolyzed, using a variety of catalysts, to give reinforcing silica particles. On the basis of the amount of silica precipitated and the extent of reinforcement, the (decreasing) order of effectiveness was found to be tetraethoxysilane, tetrapropoxysilane, tetrabutoxysilane, and tetramethoxysilane.

    Oxalato- and Malonato-complexes of trivalent metals. II. Stabilities of Tris-oxalato Complexes of Iron, Chromium, Aluminium, and Gallium (1957)
    Weinheim : Wiley-Blackwell
    Zeitschrift für anorganische Chemie 293 (1957), S. 195-203

    Topics: Chemistry and Pharmacology
    Notes: The stabilities of tris-oxalato complexes of trivalent metals like Fe, Cr, Al, Ga have been studied. These compounds have been found to decompose in steps by interaction with acids. The stepwise instability constants and also the overall instability constants of the reactions MOx3‴ → MOx′2 + Ox″, MOx′2 → MOx+ + Ox″, MOx+ → M3+ + Ox″ and MOx3‴ → M3+ + 3 Ox″ have been measured.

    Patterning and plasticity of the cerebral cortex (2005)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 2005-11-08
    Description: The cerebral cortex of the human brain is a sheet of about 10 billion neurons divided into discrete subdivisions or areas that process particular aspects of sensation, movement, and cognition. Recent evidence has begun to transform our understanding of how cortical areas form, make specific connections with other brain regions, develop unique processing networks, and adapt to changes in inputs.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sur, Mriganka -- Rubenstein, John L R -- New York, N.Y. -- Science. 2005 Nov 4;310(5749):805-10.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Brain and Cognitive Sciences, Massachusetts Institute of Technology, 77 Massachusetts Ave., 46-6237, Cambridge, MA 02139, USA. msur@mit.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/16272112" target="_blank"〉PubMed〈/a〉

    Division and subtraction by distinct cortical inhibitory networks in vivo (2012)
    Nature Publishing Group (NPG)
    Details
    Publication Date: 2012-08-11
    Description: Brain circuits process information through specialized neuronal subclasses interacting within a network. Revealing their interplay requires activating specific cells while monitoring others in a functioning circuit. Here we use a new platform for two-way light-based circuit interrogation in visual cortex in vivo to show the computational implications of modulating different subclasses of inhibitory neurons during sensory processing. We find that soma-targeting, parvalbumin-expressing (PV) neurons principally divide responses but preserve stimulus selectivity, whereas dendrite-targeting, somatostatin-expressing (SOM) neurons principally subtract from excitatory responses and sharpen selectivity. Visualized in vivo cell-attached recordings show that division by PV neurons alters response gain, whereas subtraction by SOM neurons shifts response levels. Finally, stimulating identified neurons while scanning many target cells reveals that single PV and SOM neurons functionally impact only specific subsets of neurons in their projection fields. These findings provide direct evidence that inhibitory neuronal subclasses have distinct and complementary roles in cortical computations.〈br /〉〈br /〉〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3653570/" target="_blank"〉〈img src="https://static.pubmed.gov/portal/portal3rc.fcgi/4089621/img/3977009" border="0"〉〈/a〉   〈a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3653570/" target="_blank"〉This paper as free author manuscript - peer-reviewed and accepted for publication〈/a〉〈br /〉〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Wilson, Nathan R -- Runyan, Caroline A -- Wang, Forea L -- Sur, Mriganka -- R01 EY007023/EY/NEI NIH HHS/ -- R01 EY018648/EY/NEI NIH HHS/ -- England -- Nature. 2012 Aug 16;488(7411):343-8. doi: 10.1038/nature11347.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Brain and Cognitive Sciences, Picower Institute for Learning and Memory, Massachusetts Institute of Technology, Cambridge, Massachusetts 02139, USA.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/22878717" target="_blank"〉PubMed〈/a〉
