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.

Immunohistochemistry is a powerful lab technique for evaluating protein localization and expression within tissues. Current semi-automated methods for quantitation introduce subjectivity and often create irreproducible results. Herein, we describe methods for multiplexed immunohistochemistry and objective quantitation of protein expression and co-localization using multispectral imaging.

Measurement Accuracy The ability to repeat an experiment and get the same results, or reproducibility, is essential in scientific research. However, it’s impossible to repeat an experiment if you don’t know how you did it. Thus, scientists keep detailed records of their experiments in lab notebooks. These records include important information like the amount of each material used and descriptions of each step of the procedure. Equipment, like balances and volumetric or graduated glassware, is...

Histochemical technique links a reagent response to a particular cellular or tissue component. A stain or dye is applied to a section so the target produces a visible color, while an enzyme-based reaction produces a detectable signal where the relevant activity occurs. Examining that pattern allows molecular composition to be interpreted alongside surrounding biological structure.
Spatial localization is important because the same chemical component can have different biological significance depending on which cells or tissue regions contain it. By retaining the arrangement of the section, histochemistry shows where carbohydrates, lipids, proteins, nucleic acids, or enzyme activity occur. This context connects molecular findings with tissue organization rather than treating composition as an isolated measurement.
Unlike biochemical or molecular analyses that provide composition-focused information, histochemical observations preserve the relationship between that information and tissue architecture. The method therefore serves as a visual complement rather than a replacement for those analyses. Combining approaches can relate a detected component or activity to specific cells, tissue regions, or structural changes visible in the section.
A basic workflow begins with a tissue section, followed by application of a selected stain, dye, or enzyme-based reaction. After the target produces a color or other visible signal, the prepared section is examined with light or electron microscopy. The resulting image is interpreted by considering both the detected chemical feature and its location within the preserved tissue structure.
Choice of reaction depends on the component or activity being investigated. Histochemical methods can target carbohydrates, lipids, proteins, nucleic acids, or enzyme activity, so the experimental question determines which chemical feature is visualized. Matching the method to the target shifts the analysis from general tissue appearance toward a more focused view of molecular composition.
Biologists apply these methods when location is central to the question, including studies of tissue organization, development, disease-related changes, and pathology. A visible distribution pattern can show how molecular features relate to normal structure or how they shift during biological or pathological change. This provides spatial evidence that complements other laboratory analyses.
