Анализ реотаксиса у рыбок данио-рерио: метод измерения ориентационного поведения в ответ на различные скорости потока воды

Executive Industry Relevance

Understanding orientation behavior in response to environmental stimuli provides mechanistic insights into sensory integration and navigation pathways relevant to neuropharmacology target validation. Quantitative behavioral assays like rheotaxis enable de-risking of CNS-targeted compounds by assessing functional outputs in disease-relevant systems. This supports predictive confidence in early discovery by linking genetic or pharmacological manipulations to measurable phenotypic changes in aquatic models.
