Relationships Among The Distribution Of Terminal Fields Of Sensory Afferent Projections To The Deep Layers Of The Superior Colliculus Within The Cat, Wayne Thomas Shaia

Theses and Dissertations

While it is well known that the different sensory modalities are primarily represented at separate locations within the central nervous system, there are numerous sites in which information from the different sensory modalities converge. Perhaps the best known structure where inputs from different sensory modalities converge is the superior colliculus. Here, not only are visual, auditory and somatosensory inputs present, but they also form organized representations of auditory and visual space as well a map of the body surface in addition, neurons that receive inputs from more than one sensory modality (i.e. multisensory) are found here in abundance.

Home Care Nurses And Home Care Patients: Differences In Perceptions Of Nurse Caring Behaviors, Sara K. Welsh

College of Graduate Studies: Theses & Dissertations (1964–2006)

Caring has been identified as the essence of nursing. Leininger (1988b, p. 3) even stated that "caring is nursing and nursing is caring." Caring has been studied from many different perspectives. Throughout the history of nursing the caring aspect has grown from a primarily caregiver role, to having a caring intersubjective relationship with the patient. Various studies have been conducted to try and identify which nursing behaviors make patients feel cared for. The purpose of this exploratory study was twofold: (a) to determine what were the most important nurse caring behaviors as perceived by both home care nurses and patients; …

The Effect Of 'Environmental Manipulation' On Agitation And 24-Hour Sleep In Dementia Sufferers In An Institutional Setting, Ernest A. Matthews

Theses: Doctorates and Masters

Living in an institutional setting places on residents certain constraints in relation to freedom of choice as to when, where, and how they conduct activities of daily living, such as, sleeping eating, attending to hygiene needs. Studies indicate this loss of control over the environment contributes to loss of self-esteem, leads to stress, and at times precipitates agitation among nursing home residents. Cognitive impairment may render dementia sufferers more vulnerable to loss of control over their control over their environment and result in agitation, which may in turn influence sleep. The study therefore, investigated if ‘environmental manipulation’ as in introducing …

Effects Of Dietary Calcium And Fasting On Osteoclast Recession And Recruitment In Calcium Deficient Rats, Kenneth R. Wright

Loma Linda University Electronic Theses, Dissertations & Projects

The osteoclast, a multinucleated giant cell, has as its role the resorption of bone matrix with consequent release of calcium. The osteoclast is thought to derive from a pluripotent stem cell which also gives rise to monocytes and macrophages. The development, activation, and inhibition of osteoclasts are influenced by a number of systemic and local factors. The release of these factors is influenced by changes in the dietary status of the animal. Calcium deficiency is known to stimulate the recruitment and activity of large numbers of osteoclasts. These osteoclasts can subsequently be inhibited by increasing dietary calcium intake. Disappearance of …

The Effect Of Trimethyltin On The Cholinergic System Of The Rat Hippocampus, Richard L. Cannon

Electronic Theses and Dissertations

Trimethyltin (TMT) is a neurotoxin occurring in the environment. Exposure to (TMT) is known to destroy specific neuronal components of the hippocampus in the rat and to cause clinical symptoms in exposed humans, including mnemonic deficits, that indicate hippocampal involvement. In addition to hippocampal cell loss TMT causes significant increases in cholinergic markers such as acetylcholinesterase (AChE) stain density and choline acetyltransferase (ChAT) activity in the hippocampus of rats. However, despite these observations the effect of TMT on hippocampal cholinergic system has not been investigated in detail. The purpose of the present study was to elucidate more fully the consequences …
