Select four of the six neurotransmitters listed below, and describe the functions of these neurotransmitters, whether the neurotransmitter is an excitatory or inhibitory neurotransmitter, and what effect(s) would occur from having a deficiency and/or excess of each chemical. acetylcholine, serotonin, dopamine, norepinephrine, GABA, glutamate

Question

What will be an ideal response?

Answer 1

Answer will include that acetylcholine is an excitatory neurotransmitter that participates in movement, autonomic function, learning, and memory with a deficiency of acetylcholine being linked with the development of Alzheimer's disease. Serotonin is an inhibitory neurotransmitter that participates in mood, appetite, and sleep with a deficiency leading to anxiety and/or depression. Dopamine is an excitatory neurotransmitter that participates in motivation, reward, and planning of behavior. A deficiency of dopamine may lead to Parkinson's disease or to reduced feelings of pleasure, while an excess of dopamine may lead to schizophrenia. Norepinephrine is considered to be both an excitatory neurotransmitter and a hormone. It is involved in arousal, vigilance, and mood with an excess leading to anxiety. GABA has a major inhibitory effect in the central nervous system and participates in moods with a deficiency in GABA leading to anxiety. Glutamate has a major excitatory effect in the central nervous system and is involved in learning and memory. An excess of glutamate may lead to neuron death and autism, while a deficiency may lead to tiredness.
