Sodium channels

Question 5

Which process prevents continuous stimulation of the postsynaptic neuron by removing neurotransmitters from the synaptic gap?

Accepted Answer

Computed Tomography (CT) Scan

Question 8

Which of the following is a function of the cerebellum?

Accepted Answer

Controlling voluntary movement and balance

Question 9

Damage to Broca's area in the left frontal lobe would most likely result in which of the following symptoms?

Accepted Answer

Difficulty producing fluent speech

Question 10

Which neurotransmitter is primarily involved in learning and memory and is the major excitatory neurotransmitter in the brain?

Accepted Answer

Glutamate

Question 11

A person is experiencing symptoms of Parkinson's disease, such as tremors and difficulty initiating movement. Which neurotransmitter is most likely deficient?

Accepted Answer

Dopamine

Question 12

Which brain structure acts as a relay station for sensory information on its way to the cerebral cortex?

Accepted Answer

Thalamus

Question 13

Which of the following best describes the 'all-or-none principle' of action potentials?

Accepted Answer

A neuron fires only if the stimulus is strong enough; otherwise, it does not fire at all.

Question 14

Which type of brain stimulation uses weak electrical current passed between scalp electrodes to modulate brain activity and is being researched for depression and learning enhancement?

Accepted Answer

Transcranial Direct Current Stimulation (tDCS)

Question 15

A patient with damage to the hippocampus would most likely experience which of the following?

Accepted Answer

Impaired formation of new memories

Question 16

Which of the following best explains why neurotransmitters can have either excitatory or inhibitory effects?

Accepted Answer

It depends on the receptor site on the postsynaptic neuron.

Question 17

Which neuroimaging technique is most suitable for studying changes in brain activity during cognitive tasks and tracks blood flow in real time?

Accepted Answer

Functional MRI (fMRI)

Question 18

A split-brain patient is shown a picture to the right visual field. Which hemisphere processes the image, and what is the likely outcome?
