The role of adrenoceptors in the central nervous system in male and female rat sexual behavior

Functions of Vocalization in Sociosexual Behaviors in Rats (Rattus norvegicus) in a Seminatural Environment
(Journal article; Tidsskriftartikkel; Preprint; Manuskript, 2017-01-09)

In each group, 1 or 2 males and females were devocalized, and the other subjects were sham operated. Sociosexual interactions ...
