Spatiotemporal Fluctuations Of Olfactory Stimuli And Its Detection By An Optical Method, Mitu Chandra Acharjee

Graduate Theses and Dissertations

Olfactory processing in the mammalian brain is a highly dynamic process, yet most of the olfaction experiments have been studied primarily with static stimuli. Odors in the natural environment are transported by turbulent flow of air or water. Natural odorants have fluctuations in concentration and it changes rapidly with time. These rapid fluctuations may pose some challenges to identifying an odor; on the other hand, the variation itself may provide important clues about the odor source. The goal of this thesis project was to create a similar odorant environment like the rapid odor fluctuations encountered in nature – to meet …

A Descriptive Study Of The Use Of Neurofeedback In Counseling, Khwlah Jamil Al-Ansari

Graduate Theses and Dissertations

This study examines neuro-counseling in the mental health field and the concept of neurofeedback training (NFB) as an intervention in the counseling profession. Numbers of studies have indicated that NFB may be effective in the field of counseling. The purpose of this survey study is to explore the use of neurofeedback in the field of counseling.

Additionally, the study used a quantitative descriptive survey research method and descriptive statistics. The survey was sent to members of the American Counseling Association (ACA), and 93 professionals participated. The majority of the sample was licensed professional counselors, professionals with a degree in counseling, …

Examining The Relationship Between Neurocognitive Performance And Functional Fitness Levels Among Older Adults, Kristen J. Holmes

Health, Human Performance and Recreation Undergraduate Honors Theses

The goal of this thesis was to examine the relationship between neurocognitive performance and functional fitness levels among older adults. This is important because the geriatric population is the fastest growing demographic in the United States (USDHHS, CDC & Prevention, 2012). By 2030, the older adult population is expected to double. With the cumulative health effects associated with aging and pathological disease, adults typically experience a normal decline in cognitive function termed age-associated memory impairment (AAMI) (Kramer, Colcombe, McAuley, Scalf, & Erickson, 2005; O’Brien, 1999). It is believed to be a non-progressive disorder. Mild cognitive impairment (MCI), on the other …

Characterization Of Neuronal Groups Regulating Sexual And Agonistic Behavior In Male Chicken (Gallus Gallus), Jingjing Xie

Graduate Theses and Dissertations

The study aimed to understand the neuronal regulation of male sexual and agonistic behavior in broiler breeders. First, brain structures associated with sexual and agonistic behavior were identified by mapping Fos expression. The ventromedial subnucleus of medial portion of bed nucleus of the stria teriminalis (BSTM2) was specifically activated by male courtship behavior. The medial preoptic nucleus (POM) and lateral septum (SL) were associated with both sexual and agonistic behaviors. The bed nucleus of the pallial commissure (NCPa) and the paraventricular nucleus (PVN) were closely related to stress. Second, Fos-ir neurons were phenotyped by double labeling Fos with aromatase (ARO) …

Psycho-Social Effects Of A Brain-Training Program Among Healthy Older Adults, Desma Hurley, M. Jean Turner, William C. Bailey

Discovery, The Student Journal of Dale Bumpers College of Agricultural, Food and Life Sciences

Grounded in cognitive neuroscience and social exchange theory, this research evaluated the relationship between changes in cognitive functioning and two psycho-social dimensions of life among healthy adults over the age of 70 (N=12). Specific psycho-social dimensions examined were social interaction and depression. Six females and six males participated in the study. All were white, college-educated individuals residing in a life-care residential retirement community. The participants used the Posit Science® Brain Fitness Program™, an auditory-based computer training program that improves memory and speed of processing, for forty hours over an eight-week period. Pre- and post-tests related to social interaction and depressive …
