Amygdala
100
Persistent sadness or loss of interest for at least two weeks is characteristic of this disorder.
Major Depressive Disorder
100
The body's rapid "fight-or-flight" response is primarily driven by this branch of the autonomic nervous system.
Sympathetic nervous system
100
This neurotransmitter is commonly associated with mood, anxiety, and sleep regulation.
Serotonin

This hormone helps regulate the sleep-wake cycle and is produced by the pineal gland.
Melatonin
Bonus - This hormone can be produced excessively when too much of what compound is ingested?
200
This brain region is involved in judgment, impulse control, planning, and decision making.
Prefrontal cortex
200
Excessive, difficult-to-control worry occurring more days than not for at least six months characterizes this disorder.
Generalized anxiety disorder
200
This brain process allows neural connections to strengthen or weaken in response to experience.
Neuroplasticity
200
This neurotransmitter plays a major role in reward, motivation, and psychosis.
Dopamine
200
This hormone is released during acute stress and increases heart rate and alertness.
Epinephrine
300
This structure plays a major role in memory formation and contextual learning.
Hippocampus
300
Recurrent unexpected sympathomimetic attacks followed by persistent concern or behavioral changes characterize this disorder.
Panic disorder
300
This process describes the brain's adaptation to repeated exposure to a drug, requiring more of it to achieve the same effect.
