Q

Examples of agonist function of drugs

A 
Serves as NT precursor 
Stimulates release of NT

16
Q

A drug is an antagonist if it does these things

A 
Inhibits synthesis of NT 
prevents storage of NT in vesicle 
Inhibits release of NT 
blocks postsnyptic receptors 
Stimulates autoreceptors
17
Q

Why can lithium cross BBB and displace K+ and Na +

A

It’s smaller than K+ and Na+

It’s close to them on periodic table

18
Q

What brain part is in mesolimbic pathway

A

Caudate nucleus

19
Q

A

Cerebellum
Central tegmentum
Nucleus accumbens in basil ganglia
