Eye Movement Related Single-Unit Recording In The Nucleus Reticularis Tegmenti Pontis In The Alert Monkey, William Franklin Crandall Jr.

University of the Pacific Theses and Dissertations

Nucleus Reticularis Tegmenti Pontis (NRTP) is a structure which lies in the mid-brain ventral to the oculomotor complex. Anatomical studies strongly implicate it in oculomotor function as most of its inputs and outputs are to systems previously shown to be intimately involved in eye movement generation--superior colliculus (SC) and cerebellum. These reports show an integrative structure with inputs and outputs distributed in a way well suited for performing relay and feedback tasks. Physiological data in the alert, trained monkey has been gathered in an attempt to characterize these neurons and to classify them in functional terms. Three monkeys were trained …

Population Dynamics Of Musculus Senhousia And Protothaca Staminea In Tomales Bay, California, David Mcclain Nelson

University of the Pacific Theses and Dissertations

The changes in population density, growth and biomass of two infaunal, sympatric, suspension-feeding bivalves, Musculus senhousia (Benson, 1842) and Protothaca staminea (Conrad, 1837), have been investigated over an eighteen month period in Tomales Bay, California. M. senhousia, a mussel, displays two basic spawning times, one of which occurs in late spring, while the second spawning takes place in late summer. M. staminea, a venerid, spawns once during late spring. The population density of the mussel ranged from 9,180 m-2 in early spring to 752 m-2 in the fall of 1976. M. staminea had a maximum density of 1,120 m- 2 …

Courtship And Reproduction In The Bali Mynah, Leucopsar Rothschildi (Aves : Sturnidae), Ann Patterson Marshall

University of the Pacific Theses and Dissertations

Reproductive behavior of captive Bali Mynahs (Leucopsar rothschildi) was studied at the Smithsonian Institution's Conservation and Research Center, Front Royal, Virginia. Courtship and copulation are followed by egg-laying, then incubation, hatching, brooding and feeding, fledging, and feeding. Parents become aggressive toward their young at the start of a new reproductive period, marked by a renewal of courtship.

The female does the majority of the incubation, brooding, and feeding of the young, although the male participates as well. The male performs both the bobbing· display and the crest display more than the female does. During these displays, the crest is prominently …

The Effect Of Heparin On Growth Characteristics Of Transplanted Spontaneously Occurring C3h/Hej Mouse Mammary Tumor, Muhammed Saleh Abdullah Banaja

University of the Pacific Theses and Dissertations

Mouse mammary tumor is a common form of cancer used for experimental purposes. It is relatively resistant to chemotherapy. This investigation is designed to test the effect of heparin, a naturally occurring anticoagulant, on tumor growth using a genetically uniform laboratory animal.
