Experience-Dependent Remodeling of Juvenile Brain Olfactory Sensory Neuron Synaptic Connectivity in an Early-Life Critical Period(어린 뇌 후각 감각 뉴런 시냅스 연결성의 경험 의존적 리모델링)

Executive Industry Relevance

Experience-dependent synaptic remodeling during early-life critical periods is a key inflection point for understanding neural circuit plasticity and its implications for target validation in neurodevelopmental research. This protocol enables precise, dose- and time-controlled manipulation of olfactory sensory input in Drosophila, supporting mechanistic de-risking and predictive confidence for synaptic connectivity studies. The approach provides a robust platform for dissecting gene-environment interactions relevant to early discovery and translational neuroscience portfolios.
