Cerebellum

Question 3

Which neurotransmitter is most closely associated with pleasure, reward, and voluntary movement, and is implicated in Parkinson's disease and schizophrenia?

Accepted Answer

Dopamine

Question 4

What is the primary function of the myelin sheath?

Accepted Answer

To insulate axons and speed up electrical signal transmission

Question 5

During the action potential, which ion rushes into the neuron causing depolarization?

Accepted Answer

Sodium ($Na^+$)

Question 6

Which of the following best describes the role of the prefrontal cortex?

Accepted Answer

Planning, thinking, and executive function

Question 7

A person with damage to Broca's area would most likely experience which of the following symptoms?

Accepted Answer

Question 8

Which neurotransmitter is primarily inhibitory in the central nervous system and is associated with reducing brain activity?

Accepted Answer

GABA

Question 9

Which brain imaging technique is best suited for measuring electrical activity in the brain over time?

Accepted Answer

Electroencephalography (EEG)

Question 10

A split-brain patient is shown an object in their left visual field. Which of the following is most likely to occur?

Accepted Answer

They can draw the object with their left hand but cannot verbally name it.

Question 11

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

Accepted Answer

The brain's ability to change its structure and function in response to experience or injury

Question 12

Which of the following drugs would most likely increase the effects of a neurotransmitter by blocking its reuptake?

Accepted Answer

A selective serotonin reuptake inhibitor (SSRI)

Question 13

A person is unable to form new long-term memories after a brain injury. Which brain structure is most likely damaged?

Accepted Answer

Hippocampus

Question 14

Which of the following statements about glutamate is TRUE?

Accepted Answer

It is associated with learning and memory.

Question 15

Which lobe of the brain is primarily responsible for processing auditory information and language comprehension?

Accepted Answer

Temporal lobe

Question 16

A person with damage to the occipital lobe would most likely have difficulty with which of the following?

Accepted Answer

Processing visual information

Question 17

Which of the following best describes the function of the thalamus?

Accepted Answer

Relays sensory information to the appropriate areas of the brain

Question 18

Which of the following is a correct sequence of events during neurotransmission?

Accepted Answer

Action potential reaches axon terminal → neurotransmitter released into synaptic cleft → neurotransmitter binds to postsynaptic receptors

Question 19

Which of the following best describes the effect of an antagonist drug on neurotransmission?

Accepted Answer

It blocks or impedes the normal activity of a neurotransmitter at the receptor site.

Question 20

A patient is unable to recognize faces after a stroke. Which area of the brain is most likely damaged?

Accepted Answer
