We can explain our behavior between balances of two chemicals: epinephrine and acetylcholine
Not imbalances: more complicated than that
Many neurotransmitters, perhaps about 100 belonging to three groups.
Their actions = inhibitory or excitatory. Depends on 2 types of receptors.
Some NTs work as systems that can be linked to specific behaviors and behavioural disorders
Epinephrine is excitatory. Acetycholine is inhibitory.
Fight or flight
Rest and digest
Small molecule - diet
Peptides - depend on DNA
Gases - break all the rules
Classes of NTs
Each transmitter has a name and an initial
Elements obtained from diet
Small Molecule Neurotransmitters
Eggs, beef liver, beef patty, cauliflower, navy beans, tofu
Choline obtained from diet and combines with acetate in the synapse to form ACh
Phenylalanine is an essential amino acid found in breast milk, fats, manufactured by bacteria
Major excitatory transmittior in the brain (Glu)
Major inhibitory NT (GABA)
