The adult Drosophila brain is a valuable system for studying neuronal circuitry, higher brain functions, and complex disorders. An efficient method to dissect whole brain tissue from the small fly head will facilitate brain-based studies. Here we describe a simple, one-step dissection protocol of adult brains with well-preserved morphology.

Lampreys recover locomotion after a complete spinal cord injury. However, some spinal-projecting neurons are good regenerators and others are not. This paper illustrates the techniques for housing sea lamprey larvae (and recently transformed adults), producing complete spinal cord transections and preparing wholemount brains and spinal cords for in situ hybridization.

2026
Here, a protocol is presented to assess mouse meningeal lymphatic vessels (MLVs), which play an important role in multiple neurologic diseases. The goal of this protocol is to provide an integrated method that enables both functional evaluation of tracer drainage and detailed morphological characterization of the dorsal MLVs network.
FAQs
Landmarks provide reference points for locating and separating neural structures while maintaining their original spatial relationships. During dissection, recognizing these features helps determine where surrounding tissue should be removed and where sequential cuts should be made. This organized approach supports consistent identification of brain or nerve regions and preserves anatomical information needed for later examination.
Sequential cuts allow tissue to be exposed and separated in a controlled order rather than removed unpredictably. This reduces unnecessary mechanical damage and helps preserve tissue features and spatial relationships. The resulting sample is more suitable for downstream histology, electrophysiology, imaging, or molecular analysis, where structural integrity and consistent preparation influence the usefulness of experimental observations.
Appropriate instruments and carefully controlled conditions help limit mechanical damage and tissue degradation during isolation. Their importance extends beyond the dissection itself because damaged or degraded tissue may be less suitable for subsequent analysis. Consistent handling therefore improves tissue quality and makes results easier to compare across experiments using the same anatomical targets.
Standardized steps make the exposure, identification, and isolation of neural regions more consistent between samples and experiments. Reproducibility is strengthened when investigators apply comparable cuts, use appropriate instruments, and preserve the same anatomical relationships. This consistency supports more reliable comparisons of structural observations and prepares samples in a way that can be linked to cellular or functional investigations.
A typical workflow begins by exposing the relevant anatomy, removing surrounding tissues, identifying landmarks, and isolating the selected brain or nerve region through sequential cuts. Each stage should preserve tissue features and spatial relationships while limiting damage and degradation. The isolated sample can then be directed toward histology, electrophysiology, imaging, or molecular analysis, depending on the study.
Dissected neural tissue can support several complementary forms of investigation, including histology, electrophysiology, imaging, and molecular analysis. Histology examines tissue organization, whereas electrophysiology addresses functional properties; imaging and molecular analysis provide additional structural or biological information. Careful preparation connects the original anatomical context with these cellular and functional measurements.
Researchers use a standardized approach when they need consistent anatomical samples for examination or comparison across experiments. It is especially relevant when a study must connect macroscopic brain or nerve anatomy with cellular, functional, imaging, histological, or molecular findings. The protocol helps preserve tissue quality and establishes a reproducible starting point for these different analyses.
