ABSTRACT Animals integrate information from different sensory modalities as they mature and perform increasingly complex behaviors. This may parallel differential investment in specific brain regions depending on the demands of changing inputs. To investigate developmental changes volume canonical integration regions, we used third harmonic generation imaging for morphometric analysis forebrain midbrain 5 to 90 days post fertilization (dpf) Danionella dracula , a transparent, miniature teleost fish whose is optically accessible throughout its lifespan. Relative whole volume, increased or telencephalon, higher order center, torus longitudinalis (TL), visuomotor relatively consistent 30 dpf, until it increases at 60 followed by another increase animals reach adulthood. In contrast, optic tectum (TeO), retinal-recipient target, progressively decreases 30-90 whereas across all stages semicircularis (TS), secondary auditory mechanosensory lateral line olfactory bulb (OB), direct target epithelium. sum, centers (telencephalon, TL) occurs juveniles adulthood exhibit more cognitive tasks, modality-dominant earlier (TeO) development (TS, OB). Complete optical access ’s lifespan provides unique opportunity how structure over correlates with connectivity, microcircuitry, behavior.
