Prosaccades are rapid eye movements with direct stimulus and response relations and are designed to bring the fovea onto a target or area of interest. In contrast, antisaccades require the inhibition of a prosaccade and the evocation of a saccade to a target’s mirror-symmetrical location. Previous work has shown that a remote (i.e., midline, contralateral) – but not proximal (i.e., ipsilateral) – task-irrelevant distractor relative to a visual target delays prosaccade reaction times (RT) (i.e., remote distractor effect: RDE). To my knowledge, however, no work has examined whether antisaccade RTs are similarly influenced by a RDE. Accordingly, I sought to …

P2X7 is an ATP-gated ion channel in the plasma membrane of a number of cell types. Previous in vitro studies show that P2X7 plays a role in regulating the differentiation of osteoblasts and adipocytes from mesenchymal precursors, as well as cellular metabolism and energy homeostasis. Furthermore, P2X7 has been implicated in mediating the effects of mechanical stimuli in bone. Our objective was to investigate the roles of P2X7, mechanical vibration, and their possible interaction in regulating body composition in vivo. We developed a novel method to monitor body composition during growth and aging in mice using micro-computed tomography (Chapter …
