Neurotransmitters involved in temperament?

[bonnie m. wong]

Could someone give me some leads on some papers dealing with this
topic?  I understand that there is quite a few papers on temperament
and it being partially genetically determined, but are there any
papers out there that discusses the possible neurotransmitters involved
in temperament (developmentally or otherwise)?

Actually, *any* neurochemistry involved in temperament would be
a great start for me.

thanks!
