Activation Of Long Descending Propriospinal Neurons In Cat Spinal Cord, Robert J. Adams, Robert D. Skinner, Ronald S. Remmel

Journal of the Arkansas Academy of Science

Isolated mammalian spinal cord has been shown capable of generating locomotor activity. Propriospinal systems assumed to coordinate fore- and hindlimb activity are poorly understood. This study characterizes the long descending propriospinal (LDP) neurons in terms of the location of the somas and their peripheral inputs by direct neuronal recording. Anatomical studies using axonal retrograde transport of horseradish peroxidase from the lumbar to the cervical spinal cord as a tracer first described these neurons. Two hundred and thirty-one LDP neurons were identified in electrophysiological experiments. Of these, 123 responded to natural stimulation, and about 50% of the others were activated only …

How We Look: Studies Of Oculomotor-System Neural Connections, Ronald S. Remmel, Robert D. Skinner

Journal of the Arkansas Academy of Science

The neural connections of the reticular formation (RF) with the vestibular nuclei (8V) and the ascending medial longitudinal fasciculus (MLF) were studied, because many neurons in these structures carry eye-movement and head-movement (vestibular) signals and are only one or two synaptic connections removed from eye motorneurons. We used stimulating electrodes placed in specific brainstem structures and a single-neuron recording microelectrode in anesthetized or decerebrate cats. Connections were determined when the neurons were excited either forwards (orthodromically) or backwards (antidromically) by a shock. Four classes of neurons were studied. One neuronal class in the pontine RF projects axons into the ascending …

Time And Life: Applications Of Modern Chronobiology, Lawrence E. Scheving, John E. Pauly

Journal of the Arkansas Academy of Science

Chronobiology is that branch of science which objectively quantifies and explores mechanisms of biological time structure. It is an integrating discipline that impacts on all forms of life. When physiological functions are plotted along a time scale, they appear as regularly repetitive wave forms with means, amplitudes, phasing and periods. In nature these rhythms are found to have many frequencies, from a fraction of a second (ultradian) to a year or more (infradian or circannual); and those with periods of about one day (circadian) have been explored extensively. Examples of several circadian rhythms are given for experimental animals and man. …

Effects Of Organic Compounds On Amphibian Reproduction, Wesley J. Birge, Jeffrey A. Black, Robert A. Kuehne

KWRRI Research Reports

Aquatic toxicity tests were conducted with atrazine, carbon tetrachloride, chloroform, methylene chloride, trisodium nitrilotriacetic acid (NTA), and phenol. Each compound was administered to developmental stages of three to five amphibian species. Exposure was initiated at fertilization and maintained through 4 days posthatching. Test responses included lethality and teratogenesis. Different amphibian species exhibited varying degrees of tolerance to the selected compounds. Greatest tolerance usually was observed for the more broadly adapted semi-aquatic and terrestrial species (e.g., Bufo americanus, Bufo fowleri). The more sensitive amphibians usually included those species which normally are restricted to aquatic or moist habitats (e.g., Rana …

The Effect Of Walk Or Jog Recovery From Anaerobic Work On Blood Lactate Levels And Subsequent Two-Minute Run Performance, Rick Alan Livesey

Masters Theses

The purpose of the study was to investigate the effects of a walk or jog recovery on two-minute run performances and the concentrations of blood lactate.

Eight highly trained male subjects were selected from the Eastern Illinois University Track Team. The test procedure consisted of two, maximal two-minute runs on the track for distance, separated by a 30-minute recovery. The recovery consisted of a walk at 20-minutes per mile pace or a jog at 7½ to 8 minutes per mile pace. Venous blood samples were drawn three minutes after the first run, two minutes prior to the second run, and …

Comparative Effects Of Two Avoidance Paradigms Upon Ethanol Self-Selection, Richard O. Shellenberger Ii

Masters Theses

Twelve adult male rats were given free access to a two bottle free-selection of tap water or a 10% ethanol/tap water solution in the home cage for a period of 140 consecutive days with the alcohol consumption data in the form of mg absolute ETOH/g subject weight collected daily. This study incorporated three stages. Phase I was a 40 day period of alcohol acclimation with alcohol consumption during the second 20 days constituting the baseline consumption rate. Mean baseline alcohol consumption was used to block subjects into three groups. The second phase of the study consisted of an 80 day …

Children's Responses To Medically Induced Discrete, Acute Pain, Brenda D. Ballard

University of the Pacific Theses and Dissertations

Three experiments were carried out with children in a private office on the measurement of distress caused by allergy treatment injections and on a behavioral technique to alleviate this treatment-induced distress. In Experiment 1 a rating scale to measure observable indices of distress with children receiving injections was developed and its construct validity and reliability determined. In Experiment 2, norms were derived for the sample of children studied and the nature of the expression of distress according to age and sex was examined. In Experiment 3 two treatments for alleviating the treatment-induced distress, (a) sensory information, and (b) systematic reinforcement …

Differential Effects Of Serotonin Antagonists On Hypothermia And Stereotyped Behavior Induced By Apomorphine And Lergotrile In Rats, Rolin Lee Wade

University of the Pacific Theses and Dissertations

The naturally occuring ergot alkaloids of the fungus, Claviceps purpurea, and their many derivatives have been of neuropharmacological interest for many years because of their ability to affect peripheral and central adrenergic and serotonergic systems. More recently, selected compounds such as lergotile (2-chloro-6-methyl ergoline-8-beta acetonitrile) and and bromocriptine (2-bromo-alpha-ergocryptine), have been given additional attention due to their possible therapeutic potential in the treatment of parkinson’s disease, acromegaly and other disorders. There have been considerable data published attempting to establish the mechanism(s) whereby the ergot compounds exert their effects. A large portion of these experiments involves the interaction of ergot compounds …

Market Women's Cooperatives: Giving Women Credit, Judith Bruce

Poverty, Gender, and Youth

In 1972, the Nicaraguan Foundation for Development (Fundación Nicaraguense de Desarrollo—FUNDE), one of two programs sponsored by the Nicaraguan Institute of Development, became aware of market women's need for credit. This issue of SEEDS describes FUNDE's experience in developing savings and loan cooperatives to meet this need. This summary stresses the human aspects of the process as much as the financial and technical ones. The project has been successful because the cooperatives have built upon the existing market women's culture, utilizing all the subtle and complex interpersonal relationships established over the years. In essence what the cooperatives have done is …

Response Priming Effects In A Digit Naming Task As A Function Of Target-Noise Separation, John H. Flowers

Department of Psychology: Faculty Publications

Oral naming latencies were measured for visually displayed digits that were flanked by either compatible (identical) or incompatible (different) noise digits. When target-noise spatial separation was "narrow" (1.1-deg visual angle), substantially longer latencies were observed for incompatible target-noise combinations than for compatible combinations, and this effect was greatest when the onset of the noise preceded the target by 150 msec. When target-noise spatial separation was increased to 3.3 deg, noise-compatibility effects were substantially attenuated when the noise preceded the target by 100 msec or less, but the effects reappeared with longer SOA values and reached a maximum when the noise …

A Survey Of Carryover Practices Of Public School Clinicians In Oregon, Joan Marie Cranmer Polson

Dissertations and Theses

Clinicians report that carryover management is one of the most difficult and time consuming problems they face (Johnson, 1972) yet the literature offers little data to assist clinicians in determining what methodologies should be used and which are effective in facilitating carryover. The purpose of this investigation was to determine the type of methodologies utilized by public school clinicians in Oregon to facilitate carryover with clients originally diagnosed as having articulation disorders. A secondary question dealt with the perceived effectiveness of these methodologies.
