What Was the Result When Researchers Used FMRI to Image

question 32

Multiple Choice

What was the result when researchers used fMRI to image brain activity while subjects listened to syllables that differed in place of articulation?

• A) The motor region for lip movements was more active when hearing /p/, and the tongue movement area was more active when hearing /t/.
• B) The motor region for tongue movements was more active when hearing /p/, and the lip movement area was more active when hearing /t/.
• C) Brain activity during passive listening did not overlap with the brain regions active during speaking tasks.
• D) Upon hearing any speech sound, all the articulatory regions were activated at once, as predicted by the motor theory of speech perception.

Definitions:

Parietal Area

Region of the brain located in the parietal lobe that processes sensory information such as touch, temperature, and pain, and plays a role in spatial orientation and navigation.

Occipital Cortex

The region of the brain located at the back of the head that is primarily responsible for processing visual information.

Action Potentials

Rapid and temporary electrical impulses in neurons that are fundamental for transmitting signals across the nervous system.

Neurotransmitters

Neurotransmitters are chemical messengers that transmit signals across a chemical synapse, from one neuron to another, influencing mental function and behavior.
