Our facility breeds inbreed strains of mice (BALB/cBkl, CBA/H, C3Hf/Bu, C57BL/Go, C57BL/6-Ly5, NOD, Hsd:ICR (CD-1)) for the research projects conducted mainly in Rudjer Boskovic Institute. In our animal unit two colonies of rats are developed from the Wistar stock, i.e. “Hyperserotoninemic rat” and “Wistar-Zagreb 5HT rat”. Both models are used in neuroscience research as rodent models for selected neuropsychiatric disorders as well as in related neuropsychopharmacological research.
