Chronic Circadian Disruption Increases Risk For Cardiovascular Disease, Jazmine I Benjamin
Chronic Circadian Disruption Increases Risk For Cardiovascular Disease, Jazmine I Benjamin
All ETDs from UAB
Circadian disruption is a disturbance in biological timing which can occur within or between different organizational levels, ranging from molecular rhythms within specific cells to misalignment of behavioral and environmental cycles. Previous work has shown that changing the timing of food availability is sufficient to lower blood pressure and improve insulin sensitivity in prediabetic males, demonstrating the importance of timing of food intake for cardiovascular health. Findings from our group demonstrated that less than one week of mistimed feeding is sufficient to invert diurnal blood pressure rhythms, although kidney excretory rhythms and kidney function remained aligned with the light-dark cycle. …

Integration Of Cone Photoreceptor Signals In Macaque Lgn Neurons, Paul B. Brown
All ETDs from UAB
Despite advances in the understanding of the primate visual system, much is yet to be learned about the way light signals sum to create our perception of the world. This is especially true at the simplest level of visual processing—the summation of two individual cone photoreceptor signals. How such signals combine to create visual perception has not been assessed in vivo. We used an adaptive optics scanning laser ophthalmoscope (AOSLO) to deliver binarized noise movies to identified groups of cones within the receptive fields of neurons in the macaque lateral geniculate nucleus (LGN). Recordings of neural action potentials within the …
