Maternal Hpa Axis Function During Parenting Is Associated With Reduced Brain Activation To Infant Cry And More Intrusive Parenting Behavior, Andrew Erhart
Electronic Theses and Dissertations
Previous research indicated that maternal cortisol function and maternal brain response to infant stimuli are separately related to differences in parenting behavior. Evidence from animal models have demonstrated that chronically high cortisol concentration alters brain structure and function, suggesting that studying these two mechanisms together may further improve understanding of parental behavior in human mothers. First time mothers of infants aged 1-7 months old (M age = 3 months) were recruited to participate. Mother’s cortisol concentration was measured during a naturalistic interaction with their infant and their behavior was coded for maternal sensitivity and nonintrusiveness. In a separate session using …
The Place And Role Of Pharmacy Benefit Management (Pbm) Companies In Us Healthcare System, George Mattis Ii
The Place And Role Of Pharmacy Benefit Management (Pbm) Companies In Us Healthcare System, George Mattis Ii
Electronic Theses and Dissertations
On average, prescription drugs cost US consumers more than any other developed country in the world. US drug makers claim that intermediaries in the prescription drug supply chain, companies called pharmacy benefit managers (PBM), are forcing them to increase their drug prices. PBMs counter that the discounts they receive from drug makers are channeled to insurers. This thesis will examine the role that PBMs play in the prescription drug supply chain and determine what effect they have on drug prices. This thesis will utilize a comparative static model, Structure, Conduct, Performance (SCP) framework to analyze the pharmaceutical manufacturing and the …
Mechanisms Of Sensory Adaptation In The Primate Visual System, Boris Isaac Peñaloza Rojas
Mechanisms Of Sensory Adaptation In The Primate Visual System, Boris Isaac Peñaloza Rojas
Electronic Theses and Dissertations
Under ecological conditions, the luminance impinging on the retina varies within a dynamic range of 220 dB. Stimulus contrast can also vary drastically within a scene, and eye movements leave little time for sampling luminance. In addition, the amount of information reaching our visual system far exceeds the brain’s information processing capacity. Given the limited dynamic range of its neurons and its limited capacity in processing visual information in real-time, the brain deploys both structural and functional solutions that work in tandem to adapt to the surroundings. In this work, employing visual psychophysics and computational neuroscience, we study the mechanisms …
