Basic research has established a strong relationship between stimulus induced human motivation for approach-related behavior and left-frontal electrophysiological activity in the alpha band, i.e. frontal alpha asymmetry (FAA). Since approach motivation is also of interest for various fields of applied research, several recent studies investigated the usefulness of FAA as a diagnostic tool of st...

In restrictive-type anorexia nervosa (AN) patients, physical activity is usually associated with food restriction, but its physiological consequences remain poorly characterized. In female mice, we evaluated the impact of voluntary physical activity with/without chronic food restriction on metabolic and endocrine parameters that might contribute to AN. In this protocol, FRW mice (i.e., food res...

STUDY OBJECTIVES To analyze the temporal organization of the sleep-wake cycle under food entrainment in the rat. METHODS Eighteen male Sprague-Dawley rats were chronically implanted for polysomnographic recording. During the baseline (BL) protocol, rats were recorded under a 12:12 light-dark (LD) schedule in individual isolation chambers with food and water ad libitum. Food entrainment was pe...

Objective To evaluate femoral anteversion angle (FAA) change in children with intoeing gait depending on age, gender, and initial FAA using three-dimensional computed tomography (3D-CT). Methods The 3D-CT data acquired between 2006 and 2016 were retrospectively reviewed. Children 4 to 10 years of age with symptomatic intoeing gait with follow-up interval of at least 1 year without active trea...

The primate caudate nucleus plays a crucial role in transforming cognitive/motivational information into eye movement signals. A subset of caudate projection neurons fire before a visual target's onset. This anticipatory activity is sensitive to position-reward contingencies and correlates with saccade latency, which is shorter toward a rewarded position. We recorded single-unit activity of cau...

Fertility Associated Antigen in Peripubertal Beef Bulls as an Indicator of Potential Fertility. (August 2005) Joanna Lynn Gallino, B.S., California State Polytechnic University Co-Chairs of Advisory Committee: Dr. L. R. Sprott Dr. D. W. Forrest Ejaculates from peripubertal Angus (n=106), Brahman (n=156) and Brangus (n=212) bulls were evaluated for the presence of a 31 kDa protein known as ferti...

Two thirds of US adults are either obese or overweight and this rate is rising. Although the etiology of obesity is not yet fully understood, neuroimaging studies have demonstrated that the central nervous system has a principal role in regulating eating behavior. In this study, functional magnetic resonance imaging and survey data were evaluated for correlations between food-related problem be...
