A shrine installation in the peony garden will investigate issues of spiritual and physical human interaction with the landscape. The problem of invasive tree species in Michigan's forests will be highlighted along the ridge trail. The fluctuating environment of the Huron River will be given a voice, and documentary video footage of the land management process of the prairie burn will illuminate grasses in the Dow Prairie. Together these installations point to the idea of making invisible or typically unnoticed processes of ecology and land management visible or audible. <br/> <br/>Description: Documents and learning objects related to the installation of the Digital Kami in the Nichols Arboretum.

These maps foster the emergence of stories about the city that are richer than any single author could create. The virtual digital environment created by Blue Puddle will serve as a catalyst for engaging the real built environment. <br/> <br/>Description: Videos produced to demonstrate the capability of the Blue Puddle system.

Theories of interference control differ regarding whether a single system of control acts upon multiple representations, or whether dissociable forms of control exist. Moreover, it is unclear whether control relies on the facilitation of relevant information, inhibition of irrelevant information, or both. Here, we combine cognitive psychology, functional neuromaging, and meta-analytic techniques to examine the neural and psychological mechanisms of interference control. We find common control-related activation in the dorsolateral prefrontal cortex across perceptual, memorial, and response selection. However, control networks in more posterior regions of the brain differentiate by the kinds of representations that control acts upon. We suggest that the frontal eye fields and superior parietal lobule may be most closely linked to selective attention mechanisms that underlie perceptual selection, but that these regions may also be recruited to select upon competing memorial and response representations. Interference control processes acting upon competing memories preferentially recruit left ventrolateral prefrontal cortex, which shows enhanced functional connectivity with the medial temporal lobe when selection demands are increased. Finally, response selection processes may engage the premotor cortex, and all forms of selection may be dissociable from inhibition processes that act just before motor execution. We demonstrate that at least in the perceptual domain, control processes act by a combination of facilitation of relevant information and inhibition of irrelevant information, and that inhibition can affect processing at least several seconds into the future. The role of inhibition in memory remains less clear. Our results suggest that common goal-related information stored in the dorsolateral prefrontal cortex biases processing in dissociable posterior networks responsible for different kinds of information. Hence, both common and dissociable neural and psychological mechanisms underlie interference control. Mon, 29 Oct 2007 22:58:59 GMT
