I hate it when people publish research material as if it were the discovery of the century when actually similar results had been obtained elsewhere at least 40 years before.
It indicates plagiarism or, at best, poor review of the literature.
In this thread the discussion is about the role of brain serotonin in mammals' sexual behavior. Well, it aint new, not a bit.
Have a look at this link:
Lack of copulatory behaviour in male castrated rats after p-chlorophenylalanine , by M.Del Fiacco et al, Institute of Pharmacology, University of Cagliari, Cagliari, Italy.
In the Introduction to the article, published in 1974, it is written:
"p-Chlorophenylalanine (PCPA), a compound that inhibits the synthesis of 5-hydroxytryptamine (5-HT) rather selectively (Koe & Weissman, 1966), stimulates homo- and heterosexual mounting behaviour in male animals (Sheard, 1969; Tagliamonte,Tagliamonte, Gessa & Brodie, 1969; Shillito, 1970; Ferguson, Henriksen, Cohen, Mitchell, Barchas & Dement, 1970; Hoyland, Shillito & Vogt, 1970). However, we have observed that PCPA fails to cause male to male
mounting behaviour in castrated rats, but this effect is restored and greatly potentiated by testosterone (Gessa, Tagliamonte, Tagliamonte & Brodie, 1970)".
Which indicates that a lot of research had already been done on serotonin and sexual behavior.
