Source: Lauer, S. M., et al. Visualization of Cortical Modules in Flattened Mammalian Cortices. J. Vis. Exp. (2018) This video demonstrates a method to visualize the cortical modules in flattened brain sections using histochemical staining. Pre-fixed sections are treated with a straining reagent that highlights active neural clusters, forming dark, high-contrast regions. After mounting and dehydration, cortical modules appear under a bright-field microscope as dark, patchy patterns.

The laser heated diamond anvil cell combined with synchrotron micro-diffraction techniques allows researchers to explore the nature and properties of new phases of matter at extreme pressure and temperature (PT) conditions. Heterogeneous samples can be characterized in situ under high pressure by 2D mapping and combined powder, single-crystal and multigrain diffraction approaches.

Compartment Models: Two-Compartment Model

The two-compartment model divides the body into central and peripheral compartments to account for varying blood perfusion rates among organs and tissues, affecting drug distribution. The central compartment includes blood and highly perfused tissues with rapid drug distribution, while the peripheral compartment contains tissues with slower drug distribution. After a single IV bolus dose, the drug concentration is high in plasma and low in tissues. The drug distribution between compartments...

Compartment Models: Single-Compartment Model

The single-compartment model serves as a simplified representation of the human body. This model assumes that the body functions as a single, well-mixed open compartment. When a drug is administered intravenously, it enters the body and quickly distributes uniformly. The drug then undergoes biotransformation and elimination, ultimately leaving the body. The volume of this compartment is referred to as the apparent volume of distribution into which the drug can uniformly distribute. In this...
FAQs
The flattening threshold provides a comparative indicator of how readily the enclosing fascia deforms under applied pressure. Differences in the required pressure may reflect relative changes in fascial stiffness or compliance, rather than a direct measurement of either property. This makes the value useful for comparing tissue behavior between conditions or time points while recognizing that it remains an indirect biomechanical measure.
Swelling and increased internal pressure can alter the mechanical environment surrounding the fascia, potentially changing how the compartment deforms during loading. A measured difference may therefore reflect altered compartment mechanics rather than an isolated change in the fascia itself. In medicine, this relationship is relevant because it connects the measurement with conditions in which tissue volume or internal pressure changes.
Comparisons should account for the measurement site, the technique used to apply pressure, and the properties of surrounding tissues. These factors can influence the observed flattening threshold independently of the condition being studied. Consequently, comparisons are most informative when measurements are collected under consistent conditions and interpreted as relative differences across sites, groups, or repeated time points.
A typical assessment applies pressure in a controlled manner to the fascia over an anatomical compartment while monitoring fascial shape or tissue displacement. The pressure associated with flattening is then recorded and compared with measurements from another condition, site, or time point. The procedure depends on consistent pressure application and reliable observation of the resulting deformation.
The approach can support studies of compartment syndrome, injury, exercise-related pressure changes, and responses to treatment. Researchers may use repeated or comparative measurements to examine whether compartment mechanics differ after an event or intervention. Its value lies in tracking mechanical changes that may accompany these conditions, rather than treating one measurement as a complete description of tissue status.
In compartment syndrome research, the measurement offers an indirect way to investigate changes in the mechanics of the fascial enclosure alongside swelling or increased internal pressure. It may help compare affected and unaffected conditions or follow changes over time. Interpretation still requires caution, because measurement technique and surrounding tissue properties can influence the observed pressure threshold.
