• neuron

Junita doesn't want to get out of bed. Has lost her appetite and feels tired constantly. Which neurotransmitter is likely in short supply?

• dopamine

• serotonin

• norephinephrine

• acetylcholine

• glutamate

Which neurotransmitter inhibits CNS activity in order to calm a person down during a stressful situation?

• GABA
