A low-cost electroencephalographic recording system combined with a millimeter-sized coil is proposed to drive transcranial magnetic stimulation of the mouse brain in vivo. Using conventional screw electrodes with a custom-made, flexible, multielectrode array substrate, multi-site recording can be carried out from the mouse brain in response to transcranial magnetic stimulation.

This manuscript describes the establishment of an infectious model of pneumonia in mice and the respective characterization of injury resolution along with methods for growing bacteria and intratracheal instillation. A novel approach using high-dimensional flow cytometry to evaluate the immune landscape is also described.
FAQs
Sub-millimeter resolution depends on several linked measurement properties rather than a single instrument setting. Spatial sampling determines how finely an area is represented, while signal quality affects whether adjacent details can be separated. Optics or sensor geometry and calibration then influence the smallest detail that can be resolved under the conditions of a particular environmental measurement.
The relevant resolution can change because the smallest separable detail is evaluated under specific measurement conditions. Variations in signal quality, spatial sampling, optics or sensor geometry, and calibration can therefore alter whether nearby environmental features appear distinct. Reporting those conditions helps interpret measurements accurately and prevents a resolution value from being treated as universally applicable.
Fine-scale environmental measurements are especially useful where important variation occurs over short distances. They can characterize surface texture, sediment or soil structure, small organisms, particles, and narrow spatial gradients. That detail supports closer examination of localized habitat conditions and transport or erosion processes, rather than averaging those features into a coarser observation.
An environmental workflow begins by selecting spatial sampling and sensor or optical geometry suited to the feature being measured. Researchers then consider signal quality, apply calibration, and determine the smallest separable detail under the actual measurement conditions. This evaluation links the reported resolution to the observation itself, making results more useful for analysis and comparison.
Sub-millimeter resolution is most valuable when the research question depends on localized environmental structure rather than broad spatial averages. Examples include examining habitat features, sediment or soil organization, particles, small organisms, and fine transport or erosion patterns. In these settings, resolving short-range variation can improve characterization of processes that coarser observations may obscure.
Measurements at this scale can support model validation by providing observations against which predicted environmental structure is compared. They also enable more informative comparisons of environmental change over time, provided the measurement conditions and calibration are sufficiently considered. This makes fine-resolution data useful not only for description, but also for evaluating model performance and temporal patterns.
