Neural Arches: Synopsis of the Subclasses.—Primitive rep¬tilian types (Cotylosauria) first appeared in the vast coal measures of the carboniferous at a time when amphibians w-ere at their zenith. The skeleton of one of these amphibia (Seymoitru) exhibits so many reptilian characteristics that, in the absence of information regarding its embryonic history, its relegation to the Amphibia is open to question. A cotylosaur may be rec¬ognized by the presence of swollen neural arches and the absence of temporal apertures (fenestrae) in the cranium.
Graham's work has concentrated on the quan¬tification of visual phenomena. In his early neuro-physiological work with animals, he measured the minimum light energy required to elicit a con¬stant neural response under various conditions of light and dark adaptation. He also applied the same procedural rigor to his many experiments on human subjects. The subject's verbal judg¬ment of a stimulus is taken as a unit of behavior analogous to the neural response of an animal. With the subject's perceptual capacities specified in this way, Graham was able to test such theo¬retical formulations as those that describe color discrimination or visual depth perception in quantitative terms.See Also Trans¬verse Arches:Lorsch (774) in Germany, and the complex mo¬nastic layout of St. Gall (9th century) in Switzer¬land are representative.
Italy.—The first Romanesque style to devote its energy to problems of structure arose in Lom-bardy. Partly because timber was scarce, the Lombard builders created a new system of vault¬ing. The nave of the Church at Sant' Ambrogio, Milan (1046-1071), or at San Michele, Pavia (c.1125), was divided into square bays by trans¬verse arches or ribs.
The builders of the latter liked the appearance of the six part vault but did not understand its structural significance; hence the intermediate rib carried merely a section of Wall above it to bisect the lateral compartment instead of altering the form of the vault. On the other hand, half arches under the Roof of the aisle trans¬mitted the thrusts of the nave vaults to the outer walls, an anticipation of the flying buttress in Gothic architecture.
On The Other Hand See Nor Arches [of:Before the dome was completed, Brunelleschi designed the fagade of the Foundlings Hospital (1419) with its Delia Robbia medallions. He rejected Gothic membered piers and vaults, pointed nor arches [of, tracery and pinnacles in favor of round nor arches [of on Corinthian columns, of something like an entablature, and a dominant horizontality. For the Church of San Lorenzo (1425) he chose the plan of an Early Christian Roman basilica.
nor arches [of of Science Award. The Pacific Science Center, Seattle, Wash., established the nor arches [of of Science Award in 1965; it is given to an Ameri¬can who has made "an outstanding contribution to the public understanding of the meaning of science to contemporary man." The 1967 award, $25,000 and a gold medal, was presented to James Bryant Conant, president emeritus of Harvard University.
