Prostaglandin E2-induced masculinization of brain and behavior requires protein kinase A, AMPA/kainate, and metabotropic glutamate receptor signaling.

19 Oct 2009 Prostaglandin E(2) (PGE(2)) mediates the masculinization of adult sex behavior in rats in response to the surge in serum testosterone at approximately birth. Measures of behavioral masculinization correlate with a twofold increase in spinophilin ... Read more...

Multiyear multiple paternity and mate fidelity in the American alligator, Alligator mississippiensis.

3 Oct 2009 We examined multiple paternity during eight breeding events within a 10-year period (1995-2005) for a total of 114 wild American alligator nests in Rockefeller Wildlife Refuge in south-west Louisiana. Our goals included examining (i) within ... Read more...

Estrogen masculinizes neural pathways and sex-specific behaviors.

30 Sep 2009 Sex hormones are essential for neural circuit development and sex-specific behaviors. Male behaviors require both testosterone and estrogen, but it is unclear how the two hormonal pathways intersect. Circulating testosterone activates the androgen ... Read more...
