Este artigo mudou minha vida: adotando um dos primeiros modelos de neurociência naturalística
Um artigo publicado na PNAS em 1992 mostrou que o canto das aves aumenta a expressão de um gene de resposta imediata no prosencéfalo dessas aves. O estudo revelou a Ribeiro a importância de investigar as respostas moleculares em contextos naturalísticos.
