Question 4

The autonomic nervous system is divided into two branches. Which of the following correctly matches each branch with its primary function?

Accepted Answer

Sympathetic: mobilizes the body for action; Parasympathetic: conserves energy

Question 5

Which neurotransmitter is most closely associated with mood, memory, and psychological well-being?

Accepted Answer

Serotonin

Question 6

A researcher uses transcranial magnetic stimulation (TMS) to temporarily disrupt activity in a specific brain region. What is the primary purpose of this technique?

Accepted Answer

To observe changes in behavior resulting from temporary changes in brain activity.

Question 7

Which of the following best illustrates the concept of neural plasticity?

Accepted Answer

A stroke victim regains the ability to speak after months of therapy.

Question 8

A split-brain patient is shown an object in their left visual field. Which hemisphere processes this information, and what is the likely outcome if asked to verbally identify the object?

Accepted Answer

Right hemisphere; the patient cannot verbally identify the object.

Question 9

Which brain structure is most directly involved in the formation of new long-term memories?

Accepted Answer

Hippocampus

Question 10

Which of the following statements about the two cerebral hemispheres is most accurate?

Accepted Answer

Both hemispheres cooperate in most mental activities, each contributing valuable functions.

Question 11

Which hormone is primarily responsible for regulating the sleep-wake cycle?

Accepted Answer

Melatonin

Question 12

A person is startled by a loud noise, causing their heart rate to increase and muscles to tense. Which part of the nervous system is primarily responsible for this response?

Accepted Answer

Sympathetic nervous system

Question 13

Which of the following best describes the function of glial cells?

Accepted Answer

They support, nurture, and insulate neurons, and remove debris when neurons die.

Question 14

Which brain structure is most involved in evaluating sensory information for its emotional significance and mediating anxiety and depression?

Accepted Answer

Amygdala

Question 15

A person is unable to regulate their body temperature and experiences disruptions in hunger and thirst. Which brain structure is most likely damaged?

Accepted Answer

Hypothalamus

Question 16

Which of the following is a correct statement about the effects of endorphins?

Accepted Answer

Question 17

Which lobe of the cerebral cortex is primarily responsible for processing visual information?

Accepted Answer

Occipital lobe

Question 18

A neuroscientist is interested in measuring the brain’s electrical activity in response to a specific stimulus. Which technique should they use?

Accepted Answer

Event-related potentials (ERPs)

Question 19

Which of the following best describes the role of the corpus callosum?

Accepted Answer

It connects the two cerebral hemispheres, allowing communication between them.

Question 20

A researcher finds that the cortex is thicker in women than in men, but there is no difference in performance on a memory task. What is the best conclusion?

Accepted Answer

A difference in brain structure does not necessarily produce a difference in behavior.
