The core task of this step is to select a behavioral paradigm and design a scientific neurobehavioral experiment plan. Neurobehaviorology studies nervous system function by observing animal behavior.

• Select research topic and animal: choose from learning and memory, emotion and anxiety, motor function, sensory perception, social behavior, feeding and metabolism, sleep and arousal; select model animal (mouse, rat, zebrafish, Drosophila); determine strain, age, gender, quantity
• Select behavioral paradigms: choose paradigms based on topic—learning/memory (Morris water maze, Y-maze, novel object recognition, fear conditioning), anxiety/depression (open field, elevated plus maze, forced swim, tail suspension), motor function (rotarod, gait analysis, forelimb grip strength), social behavior (three-chamber social interaction, mating preference)
• Experimental design: determine experimental groups (control, model, treatment/surgery), sample size estimation, experimental flow, behavioral testing order (non-stressful before stressful tests), control setting; consider ethical review and 3R principles (Replacement, Reduction, Refinement)

The core task of this step is to prepare experimental animals and calibrate behavioral experimental apparatus. Animal housing conditions, health status, and habituation training can all affect behavioral results.

• Animal preparation: select healthy experimental animals; house in standard animal facility (22±2°C, 50-60% humidity, 12h light/dark cycle); acclimate for at least 1 week; mark animals before experiment (ear tags, dye marking); record body weight and general condition; exclude unhealthy animals
• Apparatus calibration: calibrate behavioral equipment—water maze (water depth, temperature, platform position, camera field of view), open field/elevated plus maze (dimensions, brightness, sound insulation), rotarod (rotation speed, acceleration), fear conditioning box (sound intensity, shock intensity, camera); ensure equipment operates normally
• Pilot experiment and habituation training: conduct small-scale pilot experiment; test apparatus stability and paradigm feasibility; determine experimental parameters; perform habituation training (water maze swimming habituation, experimenter handling habituation); reduce stress effects on behavior

The core task of this step is to perform behavioral testing according to the experimental protocol and systematically collect behavioral data. Behavioral testing requires strict control of experimental conditions and consistent operations.

• Behavioral test implementation: perform all behavioral tests following SOP—control test time (fixed during specific light/dark period), maintain quiet environment (sound insulation, constant illumination), consistent experimenter operation (same handling, placement, recorder)
• Video recording and automated analysis: use behavioral video tracking systems (EthoVision, ANY-maze, TopScan) to synchronously record animal behavior videos; automatically analyze trajectory, speed, distance, residence time; manual scoring for auxiliary validation (freezing behavior, social behavior observation records)
• Data recording and quality control: use lab notebook to record testing details for each animal (date, time, experimenter, animal condition, abnormalities); perform data quality checks (video completeness, tracking accuracy); exclude invalid data promptly; backup raw data properly

The core task of this step is to perform statistical analysis on behavioral data and explain neural mechanisms of behavioral changes combined with neuroscience principles. Behavior is the external manifestation of nervous system function.

• Statistical data analysis: use GraphPad Prism, SPSS, or R for statistical analysis—descriptive statistics (mean±SEM), normality test, group comparison (t-test, one-way/two-way ANOVA, repeated measures ANOVA), post-hoc test (Tukey, Bonferroni); draw behavioral result graphs (bar charts, line graphs, heatmaps, trajectory plots)
• Behavioral indicator integration: comprehensively analyze results from multiple behavioral tests; construct behavioral profile—distinguish cognitive function, emotional state, motor ability, social ability dimensions; use PCA or factor analysis to extract main behavioral dimensions
• Neural mechanism interpretation: explain neural mechanisms of behavioral changes combined with neuroanatomy, neurophysiology, neuropharmacology knowledge—involved brain regions (hippocampus and memory, amygdala and anxiety, striatum and movement), neurotransmitter systems (glutamate, GABA, dopamine, 5-HT), neural circuit mechanisms; propose mechanistic hypothesis

The core task of this step is to write a complete neurobehavioral research report systematically presenting experimental design, methods, results, and discussion. Neurobehavioral reports should demonstrate scientific rigor.

• Write research report: follow neuroscience research paper standards—abstract, introduction, materials and methods (animals, equipment, behavioral paradigms, statistics), results (present each behavioral test in subsections), discussion (comparison with literature, mechanism discussion, limitations), conclusion, references; minimum 3500 words
• Produce behavioral figures: create high-quality behavioral result figures—trajectory plots, heatmaps, statistical bar/line charts, representative behavior photos; standard figure labeling, detailed figure/table captions, correct statistical significance markers
• Methodological discussion and limitation analysis: discuss advantages and disadvantages of behavioral paradigms; analyze possible confounding factors (animal strain, gender differences, stress levels, circadian rhythm); propose improvements and future research directions
