The segmentation clock drives oscillatory gene expression across the pre-somitic mesoderm (PSM). Dynamic Notch activity is key to this process. We use imaging and computational analyses to extract temporal dynamics from spatial expression data to demonstrate that Delta ligand and Notch receptor expression oscillate in the vertebrate PSM.

To quantify microvascular flow from high speed capillary flow image sequences, we developed STAFF (Spatial Temporal Analysis of Fieldwise Flow) software. Across the full image field and over time, STAFF evaluates flow velocities and generates a sequence of color-coded spatial maps for visualization and tabular output for quantitative analyses.

FAQs
The key variable is not only stimulus strength but where and when the signal reaches a biological system. By coordinating these dimensions, investigators can observe whether cells integrate simultaneous inputs, respond to a sequence of signals, or react differently in separate regions. This helps connect signal patterns with pathway activation and with outcomes that vary across a tissue.
Spatial control allows researchers to distinguish a response confined to a stimulated location from one that spreads across a tissue or system. That distinction is important because the same general signal can be associated with different conclusions depending on whether neighboring regions also change. Mapping position alongside response therefore clarifies local effects, tissue organization, and broader communication.
Timing can be examined as an ordered pattern rather than as an isolated event. Cells may integrate signals according to when they occur, so changing the sequence provides a way to test links between signal order, pathway activation, and functional behavior. This is especially useful when researchers want to determine whether position and sequence jointly shape a tissue response.
It can separate effects associated with stimulus location, stimulus timing, and their interaction. A response observed after a precisely placed signal may reflect a local process, whereas a response following coordinated signals at different times may reveal integration across regions. Examining these dimensions together supports more precise interpretation of cell communication, tissue behavior, development, and neural activity.
An experiment begins by specifying the locations and time points that will be compared, then selecting a stimulus category suited to the biological question. Researchers can deliver biological, chemical, electrical, or physical inputs in the planned pattern and examine resulting cellular or tissue behavior. Comparing responses across locations and sequences helps identify effects linked to each dimension.
Spatial Temporal Stimulation can coordinate biological, chemical, electrical, or physical stimuli, allowing the experimental design to match the process under study. The important consideration is how each input is distributed across locations and scheduled over time. This flexibility makes the approach relevant to questions about signaling, tissue organization, development, and neural activity rather than to one stimulus class alone.
Patterned inputs let investigators test whether cells respond only to a nearby signal or participate in a coordinated response across a tissue. Observing behavior at defined positions and times can reveal how communication relates to organization, while developmental studies can examine how changing signal patterns correspond to biological outcomes. The method therefore connects local signaling events with tissue-level structure and behavior.
