Updated project metadata. In this work we investigated how the brain proteome of the larval zebrafish is modified by behavioral adaptation to the environmental challenge of a water vortex. We monitored the behavior of larvae and observed that they behaviorally adapted to the presence of a water vortex. We obtained the larval zebrafish brain proteome by extracting brains from zebrafish larvae and analyzing them using and LFQ-based LC-MS/MS-approach. In total we identified 5929 proteins in the larval brain. Within this proteome, we identified 57 proteins that were significantly regulated following experience of the water vortex: 41 proteins were up regulated and 16 were down regulated. Of these, 29 proteins are known to have neuronal functions, 17 proteins are known to have other cellular functions, and 11 proteins are still uncharacterized.
