    Comparisons among some tetraalkoxysilanes in the hydrolytic precipitation of silica into elastomeric networks (1986)
    New York : Wiley-Blackwell

    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

    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.

    A map of visual space induced in primary auditory cortex (1990)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1990-11-09
    Description: Maps of sensory surfaces are a fundamental feature of sensory cortical areas of the brain. The relative roles of afferents and targets in forming neocortical maps in higher mammals can be examined in ferrets in which retinal inputs are directed into the auditory pathway. In these animals, the primary auditory cortex contains a systematic representation of the retina (and of visual space) rather than a representation of the cochlea (and of sound frequency). A representation of a two-dimensional sensory epithelium, the retina, in cortex that normally represents a one-dimensional epithelium, the cochlea, suggests that the same cortical area can support different types of maps. Topography in the visual map arises both from thalamocortical projections that are characteristic of the auditory pathway and from patterns of retinal activity that provide the input to the map.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Roe, A W -- Pallas, S L -- Hahm, J O -- Sur, M -- EY07719/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 1990 Nov 9;250(4982):818-20.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Brain and Cognitive Sciences, Massachusetts Institute of Technology, Cambridge 02139.〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/2237432" target="_blank"〉PubMed〈/a〉

    Orientation maps of subjective contours in visual cortex (1996)
    American Association for the Advancement of Science (AAAS)
    Details
    Publication Date: 1996-12-20
    Description: Responses to subjective contours in visual cortical areas V1 and V2 in adult cats were investigated by optical imaging of intrinsic signals and single-unit recording. Both V1 and V2 contain maps of the orientation of subjective gratings that have their basis in specific kinds of neuronal responses to subjective orientations. A greater proportion of neurons in V2 than in V1 show a robust response to subjective edges. Through the use of subjective stimuli in which the orientation of the luminance component is invariant, an unmasked V1 response to subjective edges alone can be demonstrated. The data indicate that the processing of subjective contours begins as early as V1 and continues progressively in higher cortical areas.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Sheth, B R -- Sharma, J -- Rao, S C -- Sur, M -- EY07023/EY/NEI NIH HHS/ -- New York, N.Y. -- Science. 1996 Dec 20;274(5295):2110-5.〈br /〉〈span class="detail_caption"〉Author address: 〈/span〉Department of Brain and Cognitive Sciences, Massachusetts Institute of Technology (MIT), Cambridge, MA 02139, USA. msur@wccf.mit.edu〈br /〉〈span class="detail_caption"〉Record origin:〈/span〉 〈a href="http://www.ncbi.nlm.nih.gov/pubmed/8953048" target="_blank"〉PubMed〈/a〉
