is a very informative document!

Thank you Michael

Thanks Michael I would check and get back to u

Thank you very much Farhan

Yes head twitching is commonly used.....see:

Tadano T, Satoh S, Kisara K. Head-twitches induced by p-hydroxyamphetamine in mice. Jpn J Pharmacol. 1986, 41(4):519-23.

also, circling behavior: Fleisher LN and Glick SD Hallucinogen-induced rotational behavior in rats. Psychopharmocology 62, 193-200, 1979

Auditory hallucinations as defined in DSM and elsewhere comprise noises, music and voices.   In other words, tinnitus is a simple auditory hallucination.   There are many animal models for assessing tinnitus.
