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.

¹H NMR of Labile Protons: Temporal Resolution

Protons bonded to heteroatoms such as nitrogen and oxygen exhibit a range of chemical shift values. This is due to the varying degree of hydrogen bonding between the proton and the heteroatom in other molecules. The extent of hydrogen bonding affects the electron density around the proton, thereby giving different chemical shift values for the protons in the proton NMR spectrum. The –OH proton in alcohols typically appears in the range of δ 2 to 5 ppm but can vary depending on the specific...

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.

At room temperature, the chair conformer of cyclohexane undergoes rapid ring flipping between two equivalent chair conformers at a rate of approximately 105 times per second. These two chair conformers are in equilibrium. The rapid ring flipping results in the interconversion of the axial proton to an equatorial proton and an equatorial to the axial proton. Such interconversions are too rapid and cannot be detected on the NMR timescale. Hence, the NMR spectrometer cannot distinguish between the...
FAQs
Temporal resolution is shaped by both instrument speed and the biological event under study. A method may acquire signals rapidly, yet the measured signal can still reflect a slower neural or physiological process. Researchers therefore interpret millisecond timing in relation to what the signal represents, rather than treating acquisition speed alone as a complete account of when brain activity occurred.
Spatial resolution should be interpreted as localization precision, not simply as the amount of anatomical detail in an image. When the research question concerns which brain region is involved, a method with finer localization can be more informative than one optimized for rapid timing. This distinction helps prevent researchers from choosing a technique solely because it captures changes quickly.
Temporal spatial resolution reflects complementary strengths rather than a single overall measure of method quality. A technique that captures rapid changes may provide less precise localization, whereas one that identifies brain regions more precisely may measure changes more slowly. The appropriate choice depends on whether the study prioritizes event timing, anatomical location, or both.
Researchers can begin by identifying whether the experiment primarily requires precise timing or precise localization. EEG is suited to questions involving rapid changes because it provides millisecond-scale temporal resolution, while functional magnetic resonance imaging is more useful when finer anatomical localization is central. This decision aligns the measurement characteristics with the study's main scientific question.
Combining methods can address limitations that arise when one technique emphasizes timing and another emphasizes localization. For example, EEG can contribute information about when neural signals change, while functional magnetic resonance imaging can help identify where activity is localized. Using their complementary resolution properties supports a more integrated interpretation of brain activity.
Researchers should distinguish the recorded signal's timing from the exact timing of the underlying biological event. Because temporal resolution depends partly on the process being measured, a rapid acquisition rate does not automatically establish equally precise biological timing. Careful interpretation reduces the risk of assigning more temporal precision to a neural signal than the measurement supports.
