An Introduction to Developmental Neurobiology

Developmental neuroscience is a field that explores how the nervous system is formed, from early embryonic stages through adulthood. Although it is known that neural progenitor cells follow predictable stages of proliferation, differentiation, migration, and maturation, the mechanisms controlling the progression through each stage are incompletely understood. Studying development is not only important for understanding how complex structures are assembled, but also for characterizing and...

This video describes how to dissect and isolate the adult Drosophila brain–a procedure necessary for visualizing the organ, which is otherwise obscured by the cuticle, eye, and tracheal tissue. The example protocol shows a detailed demonstration yielding high-quality preparations that can be used for immunostaining and imaging methods in Drosophila neurobiology.

The comparative species approach allows behavioral neuroscientists to explore various neurobiological factors associated with specific behaviors viewed as characteristic of a specific animal model. Taking advantage of naturally occurring differences in behavior between closely related species, this technique doesn’t require invasive techniques to manipulate the expression of the behavior.

Here we present a protocol to induce activity-based anorexia (ABA) in female adolescent mice. ABA is a condition of hyperactivity evoked by imposing food restriction on rodents with access to a running wheel. This phenomenon is being used as a model to study the underlying neurobiology of anorexia nervosa.
FAQs
Preserving orientation and landmarks allows observers to identify structures according to their anatomical relationships rather than as isolated tissues. This makes it possible to trace how the brain, spinal cord, and peripheral nerves are arranged and connected. Maintaining those relationships strengthens anatomical interpretation and helps link visible organization with sensory, motor, and other nervous-system functions.
Layer-by-layer exposure reveals structures progressively while reducing the risk of losing their position within the nervous system. Each stage can show how superficial and deeper tissues relate to one another, supporting examination of pathways and regional organization. This gradual approach also helps learners and investigators connect anatomical observations with questions about neural function, development, or injury.
A dissection can support examination of connections among the brain, spinal cord, and peripheral nerves, as well as the organization of sensory and motor systems. These relationships provide a structural basis for interpreting how signals may be organized within the nervous system. The resulting anatomical observations can guide experimental design and the interpretation of neurobiological data.
The workflow begins by establishing orientation and identifying structural landmarks, then uses fine instruments to expose tissues layer by layer. Throughout the process, the investigator preserves the position and connections of relevant structures rather than separating them indiscriminately. This sequence produces an anatomical view that can be examined for organization, pathways, and relationships among neural regions.
In education, the method gives students a direct way to connect neural form with function. Observing structures in relation to one another makes concepts such as sensory and motor organization more concrete than studying names alone. It also develops attention to anatomical landmarks and prepares students to interpret neurobiological observations and experimental findings more accurately.
Researchers can apply dissections when they need anatomical context for developmental changes or the effects of injury and disease. Comparing exposed structures or their relationships can help frame questions about how the nervous system is organized under different conditions. The observations may also support experimental planning and provide a structural basis for interpreting other neurobiological data.
