Abstract:
:How the brain becomes lateralized is poorly understood. By contrast, much is known about molecular cues that specify the left-right axis of the body, fashioning the asymmetric morphology and positioning of the visceral organs. In zebrafish, the Nodal signaling pathway functions in visceral asymmetry and also in the embryonic brain, to bias laterality of the epithalamus. Formation of an asymmetric pineal complex differentially influences adjacent diencephalic nuclei, the left and right habenulae, which acquire distinctive molecular and cellular features. Results from the genetically tractable zebrafish system provide a promising entry point for exploring how left-right biases are established and propagated in the developing vertebrate brain.
