AP Psych Neurotransmitters Functions
41 flashcards covering AP Psych Neurotransmitters Functions for the AP-PSYCHOLOGY Unit 2: Biological Bases section.
This topic covers the functions of neurotransmitters, which are chemical messengers that facilitate communication between neurons in the brain and throughout the nervous system. According to the College Board's AP Psychology Curriculum Framework, understanding neurotransmitters is essential for grasping the biological bases of behavior, as they play a crucial role in regulating mood, cognition, and physical responses.
On practice exams and competency assessments, questions about neurotransmitters often require students to identify specific neurotransmitters, their functions, and the effects of their imbalance. Common traps include confusing the functions of similar neurotransmitters or overlooking the broader implications of neurotransmitter activity on psychological conditions. For instance, students might mix up dopamine with serotonin, which can lead to incorrect answers regarding mood disorders. A practical tip for those in the field is to remember that the interplay between neurotransmitters can be just as important as understanding their individual roles, as many psychological conditions arise from complex interactions rather than single neurotransmitter deficiencies.

Serotonin has a role in regulating appetite and can influence feelings of satiety and hunger (College Board AP CED).
- 11
What is the role of dopamine in addiction?
Dopamine is heavily involved in the brain's reward pathways, making it a key player in the development of addiction by reinforcing behaviors that lead to pleasurable outcomes (College Board AP CED).
- 12
What is the primary action of acetylcholine at the neuromuscular junction?
At the neuromuscular junction, acetylcholine binds to receptors on muscle cells, triggering muscle contraction (College Board AP CED).
- 13
Which neurotransmitter is associated with learning and memory?
Glutamate is associated with learning and memory, as it is involved in synaptic plasticity, which is essential for these cognitive processes (College Board AP CED).
- 14
What is the impact of low levels of serotonin?
Low levels of serotonin are associated with mood disorders, particularly depression and anxiety, affecting emotional regulation (College Board AP CED).
- 15
Which neurotransmitter is known for its role in reducing anxiety?
GABA is known for its role in reducing anxiety by inhibiting excessive neuronal firing and promoting relaxation (College Board AP CED).
- 16
What neurotransmitter is released during pleasurable activities?
Dopamine is released during pleasurable activities, reinforcing behaviors that provide rewards and enjoyment (College Board AP CED).
- 17
How does norepinephrine affect attention?
Norepinephrine enhances attention and focus, particularly in response to stress or novel stimuli, thereby increasing alertness (College Board AP CED).
- 18
What is the function of endorphins in response to stress?
Endorphins help mitigate the perception of pain and stress, acting as natural pain relievers and mood enhancers in stressful situations (College Board AP CED).
- 19
How does glutamate contribute to neuroplasticity?
Glutamate contributes to neuroplasticity by facilitating synaptic strengthening, which is critical for learning and memory formation (College Board AP CED).
- 20
What neurotransmitter is primarily involved in the regulation of circadian rhythms?
Melatonin is primarily involved in the regulation of circadian rhythms, influencing sleep-wake cycles (College Board AP CED).
- 21
What is the effect of high levels of dopamine?
High levels of dopamine can lead to increased motivation and pleasure but may also be associated with risk-taking behavior and certain psychiatric disorders (College Board AP CED).
