  1. What major neurotransmitters are associated with mood? How are they involved in abnormal behavior?
  2. What role do emotions play in psychopathology?


Several major neurotransmitters are associated with mood, including serotonin, dopamine, norepinephrine, and gamma-aminobutyric acid (GABA). Serotonin is often referred to as the “feel-good” neurotransmitter, as it is involved in regulating mood, appetite, and sleep. Low levels of serotonin have been linked to depression, anxiety, and obsessive-compulsive disorder. Dopamine is involved in the brain’s reward system, and it plays a role in motivation, pleasure, and attention. Abnormal levels of dopamine have been associated with a range of psychiatric disorders, including schizophrenia, bipolar disorder, and addiction.
