False (B)
What is the primary function of GABA in the brain?
What is the primary function of GABA in the brain?
GABA acts as the main inhibitory neurotransmitter, reducing neuronal excitability to prevent overstimulation.

Study Notes
Neurotransmitters and their Functions
-
Dopamine:
- Produced in the substantia nigra and ventral tegmental area (midbrain).
- Brain functions: Reward, pleasure, motivation, mood regulation, decision-making.
- Body functions: Motor control, heart rate, hormone release.
-
Serotonin:
- Produced in the raphe nuclei (brainstem).
- Brain functions: Mood regulation, sleep, appetite, emotion, stabilization of mood.
- Body functions: Digestion, blood clotting, cardiovascular health.
-
Acetylcholine:
- Produced in the basal forebrain (e.g., nucleus basalis) and brainstem.
- Brain functions: Learning, memory, attention.
- Body functions: Muscle contractions, autonomic nervous system responses, heart rate.
-
GABA (Gamma-Aminobutyric Acid):
- Produced throughout the brain (inhibitory neurons).
- Brain function: Main inhibitory neurotransmitter, reduces neuronal excitability. Prevents overstimulation.
- Body function: Controls muscle tone and relaxation.
-
Glutamate:
- Produced throughout the brain (excitatory neurons).
- Brain function: Primary excitatory neurotransmitter; essential for learning, memory, and neural communication.
- Body function: Aids in metabolic functions in muscles and tissues.
-
Norepinephrine (Noradrenaline):
- Produced in the locus coeruleus (brainstem).
- Brain functions: Attention, arousal, alertness, mood regulation.
- Body functions: Fight-or-flight response, heart rate, blood pressure.
Brain Structures and Functions
- Brainstem: Regulates vital functions (breathing, heart rate, sleep).
- Hippocampus: Essential for forming and retrieving long-term memories.
- Amygdala: Processes emotions, especially fear and aggression.
- Medulla Oblongata: Manages involuntary actions (swallowing, respiration).
- Pons: Connects brain parts; aids in sleep and facial expressions.
