• Hippocampus

• Amygdala

• Cerebellum

What have researchers questioned about the neurotransmitter acetylcholine?

• Its role in muscle contraction

• Its role in the consolidation of memories

• Its role in sensory perception

• Its role in motor coordination

What is the primary function of an antagonist as described in the text?

• To enhance the action of a neurotransmitter

• To inhibit or block a neurotransmitter's action

• To promote the synthesis of neurotransmitters

• To facilitate the binding of neurotransmitters to their receptors

How does an antagonist affect the receptor site of a neurotransmitter?

• It detaches the neurotransmitter from the receptor site

• It enhances the attachment of the neurotransmitter to the receptor site

• It fits into the receptor site and blocks the action of a neurotransmitter

• It has no effect on the receptor site

Which of the following is an example of an antagonist for acetylcholine?

• Epinephrine

• Dopamine

• Scopolamine

• Serotonin

What is the role of an excitatory neurotransmitter in a neuron?

• It decreases the likelihood that the neuron will fire an action potential.

• It increases the likelihood that the neuron will fire an action potential.

• It stops the neuron from producing neurotransmitters.

• It has no effect on the neuron's action potential.

Which neurotransmitter is mentioned as playing a role in encoding memories?

• Dopamine

• Serotonin

• Acetylcholine

• GABA
