          Abstract

          Para que serve sonhar? A vasta contribuição sobre a função dos sonhos dada por Freud e Jung foi em grande parte ignorada pela ciência, pela falta de um método quantitativo e de hipóteses testáveis. Não obstante, vários resultados experimentais corroboram dois importantes "insights" psicanalíticos: 1) que os sonhos freqüentemente contêm elementos da experiência do dia anterior, denominados de "restos do dia", e 2) que estes "restos" incluem atividades mnemônicas, levando portanto a uma facilitação do aprendizado. Em particular, dados recentes sugerem que os sonhos podem desempenhar um papel essencial na consolidação das memórias, levando aquelas recentemente adquiridas a migrar do hipocampo para o neocórtex. Tomados em conjunto, estes resultados indicam a necessidade de reavaliar cientificamente o legado psicanalítico.

          Translated abstract

          What is the function of dreaming? The vast contribution on dreams made by Freud and Jung has been largely ignored by science, which harshly criticized their approach for the lack of a quantitative method and of testable hypotheses. Here I review a series of experimental results that corroborate two important psychoanalytical insights regarding dreams: 1) that dreams often contain a "day residue" of the preceding waking experience, and 2) that such "residue" includes cognitive and mnemonic activities, therefore leading to a facilitation of learning. In particular, recent data suggests that dreams may play an essential role in memory consolidation, allowing recently-acquired memories to exit the hippocampus and settle in the neocortex. Taken together, these results call for a comprehensive scientific reassessment of the psychoanalytical legacy.
