Neuroscience and Brain Function Quiz

Describe the main function of the occipital lobe. How would damage to this area affect someone’s ability to see or process color?

• It controls voluntary movements; damage would cause paralysis.

• It processes visual information; damage would impair vision or color perception.

• It regulates emotions; damage would lead to emotional instability.

• It controls speech; damage would cause difficulty in speaking.

Explain the role of Wernicke’s area in language. What symptoms might appear if this area is damaged?

• It controls motor functions; damage would cause paralysis.

• It processes auditory information; damage would impair hearing.

• It is involved in language comprehension; damage would cause difficulty understanding language.

• It regulates emotions; damage would lead to emotional instability.

What does the amygdala do, and how is it connected to emotional responses such as fear or aggression?

• It processes visual information.

• It regulates voluntary movements.

• It is involved in emotional responses like fear and aggression.

• It controls language comprehension.

Compare the sympathetic and parasympathetic nervous systems. When does each activate?

• Sympathetic activates during rest; parasympathetic activates during stress.

• Sympathetic activates during stress; parasympathetic activates during rest.

• Both activate during sleep.

• Both activate during physical activity.

What is the purpose of the corpus callosum? How do split-brain studies show this?

• It connects the spinal cord to the brain; split-brain studies show its role in reflexes.

• It connects the two hemispheres of the brain; split-brain studies show how each hemisphere functions independently.

• It regulates emotions; split-brain studies show its role in emotional responses.

• It controls voluntary movements; split-brain studies show its role in motor coordination.

Describe the function of acetylcholine. What happens when levels are too low?

• Acetylcholine helps regulate hunger; low levels cause overeating.

• Acetylcholine is involved in muscle movement; low levels can lead to paralysis.

• Acetylcholine controls sleep cycles; low levels cause insomnia.

• Acetylcholine influences social behavior; low levels lead to isolation.

What does dopamine influence in the brain? Provide one positive and one negative effect of dopamine imbalance.

• Dopamine influences memory; imbalance leads to amnesia and hyperactivity.

• Dopamine influences mood; imbalance can cause euphoria and depression.

• Dopamine influences hunger; imbalance leads to overeating and starvation.

• Dopamine influences vision; imbalance causes blindness and hallucinations.

What is the vestibular sense and how does it help with balance?

• The vestibular sense detects hunger and helps regulate eating habits.

• The vestibular sense detects sound and helps with hearing.

• The vestibular sense detects body position and helps maintain balance.

• The vestibular sense detects light and helps with vision.

What is REM rebound, and what does it tell us about the importance of REM sleep?

• REM rebound is the increase in REM sleep after deprivation, showing its importance for memory.

• REM rebound is the decrease in REM sleep after deprivation, showing its importance for hunger.

• REM rebound is the increase in REM sleep after deprivation, showing its importance for vision.

• REM rebound is the decrease in REM sleep after deprivation, showing its importance for social behavior.

Describe the activation-synthesis theory of dreams. How is it different from theories that say dreams serve a psychological purpose?

• The activation-synthesis theory states dreams are random brain activity, unlike psychological theories that focus on emotional processing.

• The activation-synthesis theory states dreams are emotional processing, unlike psychological theories that focus on random brain activity.

• The activation-synthesis theory states dreams are memory consolidation, unlike psychological theories that focus on hunger regulation.

• The activation-synthesis theory states dreams are vision processing, unlike psychological theories that focus on social behavior.
