Question 1

What is neuroimaging?

Answer 1

Techniques that allow for studying brain activity and structure by obtaining visual images in awake humans.

Question 2

Name two types of neuroimaging techniques.

Answer 2

MRI, fMRI, CAT, PET, TMS, DTI

Question 3

What is the role of the central nervous system (CNS)?

Answer 3

It consists of the brain and spinal cord and processes information from the body.

Question 4

What is the peripheral nervous system (PNS)?

Answer 4

The PNS consists of all the nerves that deliver information from the periphery to the CNS.

Question 5

What does the somatic nervous system do?

Answer 5

Gathers sensory information and sends it to the spinal cord and brain.

Question 6

What does the autonomic nervous system control?

Answer 6

It controls involuntary functions through the sympathetic and parasympathetic systems.

Question 7

What is the fight-or-flight response?

Answer 7

The body’s reaction to stress, controlled by the sympathetic nervous system.

Question 8

What is the function of afferent neurons?

Answer 8

Carry signals from the PNS to the CNS.

Question 9

What is the function of efferent neurons?

Answer 9

Carry signals from the CNS to the PNS muscles and glands.

Question 10

What is a reflex circuit?

Answer 10

A circuit where sensory information travels into the spinal cord and triggers movement via motor neurons.

Question 11

What is the role of the hindbrain?

Answer 11

Regulates basic life functions like breathing and heart rate.

Question 12

What is the medulla responsible for?

Answer 12

Regulates heartbeat, breathing, sneezing, and coughing.

Question 13

What is the function of the pons?

Answer 13

Acts as a bridge between the medulla and other brain areas.

Question 14

What is the cerebellum’s role?

Answer 14

Important for motor coordination and movement learning.

Question 15

What happens when the reticular formation is severed?

Answer 15

Causes coma and prevents waking.

Question 16

What is the function of the thalamus?

Answer 16

Serves as a relay station for sensory information.

Question 17

What is the hypothalamus important for?

Answer 17

It controls motivation, basic drives, and the endocrine system.

Question 18

What does the pituitary gland regulate?

Answer 18

Regulates hormones in the body.

Question 19

What does the hippocampus contribute to?

Answer 19

Involved in learning and memory.

Question 20

What is the basal ganglia responsible for?

Answer 20

Cognitive flexibility and voluntary movement control.

Question 21

What role does the cerebral cortex play?

Answer 21

Responsible for higher functions like consciousness, language, and thought.

Question 22

What does the motor cortex control?

Answer 22

Controls voluntary movements of the body.

Question 23

What does the somatosensory cortex process?

Answer 23

Processes touch, pressure, temperature, and pain sensations.

Question 24

Where is Broca’s area located and what does it control?

Answer 24

Located in the frontal lobe, it controls speech production.

Question 25

What is Wernicke’s area responsible for?

Answer 25

Language comprehension, located in the temporal lobe.
