Dopamine D1 Receptor Activity In The Basolateral Amygdala Is Important For Mediating Fear, Reward And Safety Discrimination Learning, Ka Ho Ng
Open Access Theses
Post traumatic stress disorder (PTSD) patients frequently show impairment in safety learning (Jovanovic, Kazama, Bachevalier, & Davis, 2012). Since the amygdala is known to be critical for emotional processing(Wassum & Izquierdo, 2015) and dopamine signaling in the amygdala is important for mediating both fear and reward learning, current experiments examined the role of dopamine signaling in the BLA in mediating both safety learning and reward seeking. We manipulated dopamine D1 receptor activity with a D1 receptor agonist (SKF 38393) or D1 receptor antagonist (SCH23390) either systemically or infused directly into the BLA 20 minutes prior to training rats in a …
The Impact Of An Omega-3 Enriched Diet On Hyperactivity And Biochemistry In An Animal Model For Attention-Deficit/Hyperactivity Disorder, Nadine M. Hammoud
The Impact Of An Omega-3 Enriched Diet On Hyperactivity And Biochemistry In An Animal Model For Attention-Deficit/Hyperactivity Disorder, Nadine M. Hammoud
Open Access Theses
Attention-deficit/hyperactivity disorder (ADHD) is the most diagnosed behavioral disorder in children. It affects around 5% of children worldwide and 11% of children in the United States, with rates increasing. Pharmaceutical treatments, such as amphetamines and methylphenidates, are not effective for everyone and are known to have unwanted side effects. While the etiology of the disorder is not yet fully understood, there are clear genetic and environmental components. Nutritional insufficiencies have recently become a popular environmental risk factor under investigation. Essential fatty acids (EFA), omega-3 polyunsaturated fatty acids (PUFA) in particular, are needed for proper brain development and function. Our lab …
Postural Sway In Infants At Low And High Risk For Autism Spectrum Disorder, Rachel C. Harris
Postural Sway In Infants At Low And High Risk For Autism Spectrum Disorder, Rachel C. Harris
Open Access Theses
ABSTRACT Harris, Rachel C. M. S., Purdue University, December 2014. Postural Control in Infants at Low and High Risk for Autism Spectrum Disorder. Major Professor: Laura J. Claxton. Autism Spectrum Disorder (ASD) is a neurodevelopmental disorder more commonly known for deficits in social and communication skills. More recently, aspects of motor development have been shown to be delayed in children with ASD, including deficits in their postural control abilities. Children with ASD have difficulty integrating information from their sensory systems to help control their balance. Infants at risk for ASD and infants who are later diagnosed with ASD have delays …
Anticipatory And Reactive Responses To Chocolate Restriction In Frequent Chocolate Consumers, Chelsey L. Keeler
Anticipatory And Reactive Responses To Chocolate Restriction In Frequent Chocolate Consumers, Chelsey L. Keeler
Open Access Theses
Many individuals have difficulty adhering to a weight loss diet. One possible explanation could be that dietary restriction paradoxically contributes to overconsumption. The objective of this study was to examine ingestive behavior under a forced chocolate restriction, with a focus on the anticipatory restriction period and the post-restriction period in frequent chocolate consumers. Fifty-six male (N=18) and female (N=38) high chocolate consumers with high or low cognitive disinhibition aged 27.70 ± 11.09 years with a mean BMI of 25.68± 5.92 kg/m2 participated. Chocolate snacks were provided for the first, second, and sixth week of the study to establish baseline, pre-restriction …
Consumer Perceptions Of Child-Friendly Shaped Healthy Fruit And Vegetable Snacks, Selena Lauren Baker
Consumer Perceptions Of Child-Friendly Shaped Healthy Fruit And Vegetable Snacks, Selena Lauren Baker
Open Access Theses
Fruits and vegetables (FV) are widely recognized as healthful foods by the public, and most individuals are aware of dietary guidance recommendations to consume more FV. However, actual consumption of FV has been and continues to be low in the United States and many other countries, despite public health efforts to change this trend. The sub-optimal intake of FV among children and adolescents is of particular concern due to high nutrient requirements for proper growth and development during these life stages. Fruit and vegetable intake patterns in childhood have been shown to track into later life and may affect individuals' …
