I am aware of some animal models of mania. Rapid cycling, for instance, could easily be detected in animal. (Ie. they are hyperactive/hypersexual for days, and then seem to crash and not move for days)

I do know that there are big bucks put into reasearch nowadays to see how SSRI's can influence these behaviors, as well as influencing genes that have been linked with instability.

I know that there are animal models used which are often sucessfull at findind potential mood stabalizing agents. A dexamphetamine-chlordiazepoxide model was used to identify keppra as a potential mood stabilizer.

Methamphetamine is often used to replicate an animal model of mania with psychotic features.

There is some evidence that the GRK3 (G protein receptor kinase) enzyme is involved in mania, and perhaps psychosis. Expression is elevated in mania, and the state is readily reproducable in mice by administration of stimulants (don't know about antidepressants)

PACAP is another (enzyme?) that is influcenced oppositly by antidepressants and mood stabalizers, and is under investigation.
