A Neuronal Circuit Architecture for Angular Integration in Drosophila
… neurons each exist in two subtypes, with spatiotemporal activity profiles that suggest opposing roles for each subtype at the start and end of a turn. Shifting neurons are required for the heading system to properly track the fly's heading in the dark, and their stimulation induces a shift …

Dissection of spatiotemporal intracellular signaling using engineered chemical and genetic tools
… mechanisms for modulating signaling protein activity. Scientists seeking to engineer systems that mimic endogenous pathways must be able to control and precisely tune the spatiotemporal activity of the proteins involved in these complex networks. This thesis describes the development of …

A DYNAMIC LANDSCAPE OF FEAR: HUMAN IMPACTS ON CARNIVORE COMMUNITIES
… Further, growing evidence shows that human activity can impact carnivore behavior and community structure by altering predator-prey interactions, shifting diel activity patterns, and altering wildlife movement leading to increased sightings, nuisance reports, and harvests. To investigate how …

Spatiotemporal Dynamics of CaMKI During Structural Plasticity of Single Dendritic Spines
… regulatory role based on differences in the spatiotemporal dynamics of activity. While the function and activity of CaMKII in synaptic plasticity has been extensively studied, that of CaMKI, another major class of CaMK required for LTP, still remain elusive. </p><p>Here, we develop a …

USING SOCIALLY SENSED BIG DATA TO MODEL PATTERNS AND GEOGRAPHIC CONTEXT OF HUMAN ACTIVITIES IN CITIES
… in turn, the knowledge of socioeconomic status-activity relationships can contribute to understanding the social landscape of a city; 2) how different types of activities are located in space and time in three U.S. cities and how the spatiotemporal activity patterns in these cities characterize …

Optimization of fluorescence lifetime imaging microscopy (FLIM) for studying the activity of enzymes in live cancer cells
… very few reports have quantitatively studied the activity of this enzyme in live cells. Even fewer reports have examined the spatiotemporal activity of MT1-MMP in live cells cultured in 3-dimensional settings such as matrices of ECM proteins. These 3-dimensional settings can parallel the …

Seasonal use and mortalities of mammals along the Phalaborwa – Hoedspruit railway line in Balule Nature Reserve, South Africa.
… loss. There is growing evidence that human activity negatively affects the spatial distribution of wildlife in relation to the distance from the infrastructure and wildlife also adjust their spatiotemporal activity to avoid or minimize encounters of human activity. Moreover, wildlife …

In vitro selection of DNAzymes selective for monovalent metal ions and their development as sensors in living cells and organisms
… a shortage of methods to probe metal ions with activity control at specific space and time, especially in vivo. To overcome this limitation, the work in the Chapter 6 developed a Zn2+-specific near-infrared (NIR) DNAzyme nanoprobe for in vivo Zn2+ profiling with spatiotemporal activity control …
