The Habenula (Hb), an evolutionarily conserved diencephalic nucleus crucial for adaptive behaviors, undergoes sequential neurogenesis in developing zebrafish, forming organized neuronal ensembles. Despite the increasing complexity of adaptive behaviors observed in developing zebrafish, the contribution of Hb neurogenesis to sensory and limbic integration remains unclear. Using in vivo birth-dating and functional brain imaging, we examined sensory-evoked activity in Hb neurons born at different developmental stages and their telencephalic input regions. Molecular markers identified distinct Hb
