Psych 101 Neurotransmitters
38 flashcards covering Psych 101 Neurotransmitters for the PSYCHOLOGY-101 Intro Psych Topics section.
Neurotransmitters are chemical messengers that transmit signals across synapses in the brain, playing a crucial role in regulating mood, behavior, and cognitive functions. The American Psychological Association (APA) outlines the importance of understanding neurotransmitters in its guidelines for introductory psychology courses, emphasizing their relevance to mental health and neurological disorders.
In practice exams or competency assessments, questions about neurotransmitters often focus on their types, functions, and the effects of imbalances. Common question styles include multiple-choice scenarios that require identifying specific neurotransmitters associated with various psychological conditions. A frequent pitfall is confusing the functions of similar neurotransmitters, such as dopamine and norepinephrine, which can lead to incorrect answers.
To enhance understanding, remember that real-world applications of neurotransmitter knowledge can inform treatment plans, yet many overlook the importance of considering how lifestyle factors, such as diet and exercise, can influence neurotransmitter levels.

Norepinephrine enhances attention and responsiveness to stimuli, particularly in stressful situations (Hockenbury Psychology, Chapter on Biological Psychology).
- 13
What is the significance of neurotransmitter receptors?
Neurotransmitter receptors are critical for the action of neurotransmitters, as they determine the response of the receiving neuron (Myers Psychology, Chapter on Biological Bases of Behavior).
- 14
How do antidepressants affect neurotransmitter levels?
Antidepressants often work by increasing levels of neurotransmitters like serotonin and norepinephrine in the brain (Hockenbury Psychology, Chapter on Biological Psychology).

- 17
What neurotransmitter is linked to feelings of well-being?
Serotonin is linked to feelings of well-being and happiness, playing a key role in mood regulation (Myers Psychology, Chapter on Biological Bases of Behavior).
- 18
How does the body respond to increased levels of dopamine?
Increased levels of dopamine can enhance feelings of pleasure and reward, influencing motivation and behavior (Hockenbury Psychology, Chapter on Biological Psychology).
- 19
What is the effect of high glutamate levels?
High levels of glutamate can lead to excitotoxicity, which may damage neurons and is implicated in various neurological disorders (Myers Psychology, Chapter on Biological Bases of Behavior).

What neurotransmitter is often referred to as the 'feel-good' chemical?
Dopamine is often referred to as the 'feel-good' chemical due to its role in pleasure and reward pathways (Myers Psychology, Chapter on Biological Bases of Behavior).
- 22
How do endorphins function in the body?
Endorphins function as natural pain relievers and mood enhancers, often released during exercise and stress (Hockenbury Psychology, Chapter on Biological Psychology).

What is the role of neurotransmitters in synaptic transmission?
Neurotransmitters are released from the presynaptic neuron and bind to receptors on the postsynaptic neuron, facilitating synaptic transmission (Myers Psychology, Chapter on Biological Bases of Behavior).
- 24
What neurotransmitter is associated with anxiety disorders?
GABA is associated with anxiety disorders, as it helps to inhibit excessive neuronal activity (Hockenbury Psychology, Chapter on Biological Psychology).
- 25
What is the primary neurotransmitter involved in the reward system?
Dopamine is the primary neurotransmitter involved in the brain's reward system, influencing feelings of pleasure and reinforcement (Myers Psychology, Chapter on Biological Bases of Behavior).
