Final answer:
The two neurotransmitters that are most responsible for waking EEG are acetylcholine and norepinephrine.
Step-by-step explanation:
The two neurotransmitters that appear to be most responsible for waking EEG are:
A. Acetylcholine and norepinephrine
Dopamine, serotonin, and norepinephrine are neurotransmitters that are associated with other processes in the brain, but they are not primarily responsible for waking EEG.
GABA and glutamate are amino acid neurotransmitters, which mainly have inhibitory and excitatory effects, respectively, but they are not the primary neurotransmitters responsible for waking EEG.
Endorphins and melatonin are also not the primary neurotransmitters responsible for waking EEG.
