• Controlling motor functions

• Forming new memories

• Processing visual information

Explain how genetic predisposition can influence behavior. Provide an example to support your explanation.

• Genetic predisposition has no influence on behavior.

• Genetic predisposition can influence behavior by determining physical traits only.

• Genetic predisposition can influence behavior by interacting with environmental factors, such as a person with a genetic predisposition for high intelligence excelling in a stimulating educational environment.

• Genetic predisposition solely determines behavior without any environmental influence.

Describe the process of neural communication from the release of neurotransmitters to the generation of an action potential in the postsynaptic neuron.

• Neurotransmitters are released from the axon terminal, cross the synaptic gap, bind to receptors on the postsynaptic neuron, and if the signal is strong enough, an action potential is generated.

• Neurotransmitters are released from the dendrites, cross the synaptic gap, bind to receptors on the axon terminal, and if the signal is strong enough, an action potential is generated.

• Neurotransmitters are released from the cell body, cross the synaptic gap, bind to receptors on the postsynaptic neuron, and if the signal is strong enough, an action potential is generated.

• Neurotransmitters are released from the axon terminal, cross the synaptic gap, bind to receptors on the postsynaptic neuron, and if the signal is weak, an action potential is generated.

Which brain structure is responsible for regulating vital functions such as heart rate and breathing?

• Cerebellum

• Medulla oblongata

• Thalamus

• Hypothalamus

DOK Level 1: Recall

Analyze the role of dopamine in both normal brain function and in the development of mental disorders such as schizophrenia.

• Dopamine is only involved in motor control and has no role in mental disorders.

• Dopamine is involved in reward and pleasure pathways, and an imbalance can contribute to mental disorders like schizophrenia, where excess dopamine activity is linked to symptoms such as hallucinations.

• Dopamine is involved in regulating sleep and has no role in mental disorders.

• Dopamine is involved in memory formation and has no role in mental disorders.

What is the role of the myelin sheath in neural communication?

• It generates action potentials.

• It insulates axons to increase the speed of neural impulses.

• It releases neurotransmitters.

• It processes sensory information.

DOK Level 1: Recall

Compare and contrast the roles of the amygdala and the prefrontal cortex in emotional regulation.

• The amygdala is involved in processing emotions like fear and aggression, while the prefrontal cortex is involved in higher-order functions such as decision-making and moderating social behavior.

• The amygdala is involved in motor control, while the prefrontal cortex processes sensory information.

• Both the amygdala and the prefrontal cortex are involved in motor control.

• The amygdala processes visual information, while the prefrontal cortex regulates heart rate.

DOK Level 2: Skill/Concept

Design an experiment to investigate the genetic basis of a specific behavior, such as anxiety, in a population of lab mice.

• Use a single group of mice and observe their behavior without any genetic manipulation.

• Use two groups of mice, one with a genetic modification that increases anxiety-related genes and one control group, and compare their behavior in anxiety-inducing situations.

• Use a single group of mice and expose them to different environments without any genetic manipulation.

• Use two groups of mice, one with a genetic modification that decreases anxiety-related genes and one control group, and compare their behavior in non-anxiety-inducing situations.

Identify the neurotransmitter that is primarily inhibitory and is known to reduce neuronal excitability throughout the nervous system.

• Glutamate

• Dopamine

• GABA

• Norepinephrine
