This category includes specialized tools and systems used in neuroscience research involving animal models. Designed for high-precision manipulation, monitoring, and intervention, these instruments enable researchers to study brain function, behavior, and physiology in controlled experimental environments. Typical devices include stereotaxic frames, microinjectors, optogenetic systems, electrophysiology rigs, and behavioral testing apparatus. Unlike clinical imaging equipment, preclinical neuroscience tools are intended for laboratory use in academic, pharmaceutical, and biomedical research settings.
