Wild type mice

MAO A/B double

MAO A KO mice


Slide6 l.jpg

Forebrain-specific transgenic MAO A KO mice

5-HT, NE, DA normal level in forebrain

No aggression

MAO B KO mice

PEA 

No aggression

MAO A/B double KO mice

5-HT, NE, DA  

PEA  

Anxiety

Disregulation of heart rate

MAO A KO mice

5-HT, NE, DA 

aggression

Different levels of 5-HT lead

to different signaling pathways

which lead to different behaviors

The increased 5-HT in forebrain

is responsible for aggression

USC Addiction and Violence Research Center

For Studying the Cause, Treatment and Prevention

of Drug Abuse and Violence

Addiction and Violence:

Clinical Studies

*Psychological traits

*Psychiatric diagnosis

(addiction, depression anxiety, aggression)

D. Holschneider, J. Victoroff

USC Keck School of Medicine

Addiction: Social Studies

Using 10,000 methamphetamine abusers

*Demographics (gender, twins, ethnicity, type of substance, criminal justice status)

*Social factors (employment and environmental stressors)

*Developmental factors (childhood development, maternal smoking and substance use)
