Emergent categorical representation of natural, complex sounds resulting from the early post-natal sound environment

Highlights • Early exposure to naturalistic complex sounds shapes refined STRFs. • Early experience shapes sparse representation of natural sounds. • Exposure to natural sounds results in categorical representations of the sounds. • The refinement in sound representations is specific to the experien...
