2016
This article describes a simple and reproducible protocol to manipulate dissolved oxygen conditions in a laboratory setting for animal behavior studies. This protocol may be used in both teaching and research laboratory settings to evaluate organismal response of macroinvertebrates, fishes, or amphibians to changes in dissolved oxygen concentration.

Drosophila as a Model Organism The common fruit fly, Drosophila melanogaster, is a widely used model organism in biology, though it may be more commonly recognized as a fruit-loving pest. There are multiple reasons that make D. melanogaster an excellent experimental organism: their roughly two-week generation time allows studying multiple generations, they are easily maintained in very small tubes, and their sexual dimorphism enables investigators to easily distinguish between males that have...

Making Choice Chambers ExpandBefore beginning the experiments, use one of the Sharpies from the lab table to trace a line around the circumference of the bottom of both bottles. One line should be 1 cm from the base of the bottle and the other should be 1.5 cm from the base of the bottle. Use a razor blade to make a small cut in each bottle at the mark. Then, insert the scissors and carefully cut along the line until the bottoms of the bottles are removed completely. Fit one bottle bottom into...

D. Melanogaster Care ExpandObtain the Drosophila melanogaster specimens at least two weeks before the experiment to allow the specimens to acclimate to the lab room conditions. NOTE: 25 Drosophila adults produce about 50 new adults in two weeks. Each colony-housing container should consist of a clean vial, 1.5 – 3 cm of prepared food medium, and a stopper. Use a funnel to transfer the flies to the colony-housing container. NOTE: House the colonies so there will be approximately 40 flies per...

FAQs
An ethogram converts observable actions into defined behavioral categories, making scoring more consistent across observations. This matters because neuroscience experiments need behavioral measures that can be related to brain activity, sensory processing, motivation, or neural circuit function. Clear categories also help reduce observer bias when researchers compare animals or experimental conditions.
These measures describe different features of a behavioral pattern. Frequency indicates how often an action occurs, duration shows how long it persists, and sequence captures the order in which behaviors appear. Examining them together can reveal consistent responses to internal states, environmental conditions, or social interactions rather than relying on a single observation.
Controlled stimuli give researchers a defined condition against which behavioral responses can be recorded and compared. By relating a measured action to a specific stimulus, investigators can examine how sensory processing, motivation, or other nervous system functions are reflected in behavior. This approach helps connect observable outcomes with possible neural circuit activity.
Consistent behavioral patterns offer measurable outcomes for studying relationships between nervous system function and action. When observations are considered alongside brain activity, neural injury, drugs, or gene and circuit manipulation, changes in behavior can help researchers examine effects on learning, memory, motivation, sensory processing, or neural circuit function in living organisms.
A basic workflow begins by identifying behaviors of interest and organizing them into defined categories or an ethogram. Researchers then observe responses under relevant environmental, social, internal, or controlled-stimulus conditions. They record frequency, duration, and sequence, then analyze recurring patterns to relate behavioral outcomes to the neuroscientific question being studied.
Systematic recording applies the same behavioral definitions and measurement types across observations. Recording frequency, duration, or sequence creates structured information that can be examined for recurring patterns. Minimizing observer bias is especially important when comparing responses associated with different conditions, drugs, neural injuries, or experimental manipulations.
Researchers use it to assess learning and memory, evaluate responses to drugs or neural injury, and examine the effects of gene or neural circuit manipulation. The resulting behavioral measurements provide an outcome that can be compared with changes in nervous system function, helping connect experimental interventions to actions displayed by living organisms.
Observations can show whether a manipulation is associated with a change in defined behavioral patterns. Measures such as frequency, duration, and sequence allow researchers to describe the form and consistency of that change. In neuroscience, these outcomes help relate altered behavior to neural circuit function while preserving behavior as a measurable result.
