  2. PET

  3. EEG

  4. MEG
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

fMRI (functional magnetic resonance imaging) is a neuroimaging technique that measures brain activity by detecting changes in blood flow, and is commonly used to study the neural basis of language.

Multiple choice

  4. It varies depending on the individual
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In most individuals, the left hemisphere of the brain is dominant for language processing, including speech production and comprehension.

Multiple choice

What is the term for the phenomenon where individuals with brain damage to the left hemisphere may show language processing in the right hemisphere?

  1. Language lateralization

  2. Language activation

  3. Language dominance

  4. Language reorganization
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Language reorganization refers to the phenomenon where individuals with brain damage to the left hemisphere may show language processing in the right hemisphere, indicating the brain's capacity for neuroplasticity.

Multiple choice

Which theory of memory proposes that memories are stored in the brain as distributed patterns of activity across multiple neurons?

  1. The engram theory

  2. The holographic memory theory

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The distributed memory theory is a theory of memory that proposes that memories are stored in the brain as distributed patterns of activity across multiple neurons. This theory was first proposed by Donald Hebb in 1949.
