We describe a Flippase-induced intersectional Gal80/Gal4 repression (FINGR) method, allowing tissue-specific FLP to determine Gal80 expression patterns. Wherever Gal4 and FLP overlap, Gal4 expression is turned on (Gal80 flipped out) or off (Gal80 flipped in). The FINGR method is versatile for clonal analysis and neural circuit mapping.

Drosophila Larval IHC

Immunohistochemistry (IHC) is a technique used to visualize the presence and location of proteins within tissues. Drosophila larvae are particularly amenable to IHC because of the ease with which they can be processed for staining. Additionally, the larvae are transparent, meaning that some tissues can be visualized without the need for dissection. In IHC, proteins are ultimately detected with antibodies that specifically bind to “epitopes” within the protein of interest. In order to preserve...

This protocol details a streamlined method used to conduct live cell imaging in the context of an intact larval brain. Live cell imaging approaches are invaluable for the study of asymmetric neural stem cell divisions as well as other neurogenic and developmental processes, consistently uncovering mechanisms that were previously overlooked.

Drosophila melanogaster larvae provide an ideal model system to investigate the mechanisms of axonal transport within larval segmental nerves. Using this procedure, 3rd instar larvae carrying various mutations can be compared to wild type larvae.
FAQs
Sensory information enters neural circuits, where neurons integrate signals through synaptic connections before producing motor commands. This organization links environmental input with behaviors such as feeding, movement, and responses to changing conditions. Studying the sequence from sensory processing to motor output helps researchers examine how circuit structure supports specific behavioral decisions.
Neurons provide the signaling pathways that receive information, integrate activity, and generate motor commands, while glial cells are also part of the developing nervous system. Examining both cell types gives researchers a broader view of circuit development rather than focusing only on synaptic connections. This cellular perspective supports studies of how neural systems become organized.
Behavior depends on how neurons are connected and how those connections integrate incoming signals with outgoing commands. The larval CNS provides a compact setting for tracing this organization as circuits develop. Researchers can therefore relate cellular connectivity to feeding, locomotion, and environmental responses, clarifying general principles of how nervous systems coordinate behavior.
Live imaging allows researchers to observe the larval CNS while examining circuit development at cellular precision. Used alongside the system’s genetic accessibility, it can help connect visible developmental changes with particular neural components or circuit arrangements. This approach is especially useful when the goal is to follow organization over time rather than assess behavior alone.
A study can begin by identifying neural components or circuits through genetic access, then tracing their connections as the CNS develops. Researchers may use live imaging to observe organization and targeted manipulation to test neuronal function. Behavioral observations, including feeding, movement, or environmental responses, can then relate cellular changes to circuit output.
Targeted manipulation is useful when researchers need to test whether a particular neural component contributes to circuit function or behavior. Because the larval CNS permits cellularly precise intervention, investigators can examine effects on motor commands and behaviors such as feeding or movement. This moves analysis beyond correlation toward functional testing of neuronal activity.
This model supports research on synaptic connectivity, circuit organization, and nervous-system development. Its compact structure and genetic accessibility make it practical for linking individual cells with circuit-level functions and behavior. Findings from these studies can inform broader neuroscience by revealing principles that apply to how neural systems develop and coordinate responses.
