brainstem

Hey guys I need some help. So I have science fair on thursday, (and it's due by tuesday..eek) so i'm researching on how drugs may induce/cause schizophrenia, and how they(drugs) affect the brain. I'm kind of going with the whole overreacting dopamine theory, and i'm wondering how some drugs may affect the dopamine levels in the brain, and what happens. I've been researching a lot and it's been hard to find some pretty recent information. Maybe I should change my topic and narrow it down to some other point? Oh yeah, and I would've just done schizophrenia in general but some girls took my idea so I wanted to change mine a bit so that I can beat them ! sorry if this is a total waste of your time
