We can explain our behavior between balances of two chemicals: epinephrine and acetylcholine
Not imbalances: more complicated than that
New ideas
-
Many neurotransmitters, perhaps about 100 belonging to three groups.
1.
Their actions = inhibitory or excitatory. Depends on 2 types of receptors.
2.
3.
Epinephrine is excitatory. Acetycholine is inhibitory.
Fight or flight
Rest and digest
Small molecule - diet

Peptides - depend on DNA

Gases - break all the rules
