Question 1:

Which brain imaging technique measures changes in blood oxygenation to infer neural activity?

Explanation: Functional magnetic resonance imaging (fMRI) measures changes in blood oxygenation to infer neural activity. It is a non-invasive technique commonly used in cognitive neuroscience research.

Question 2:

Which brain imaging technique involves injecting a radioactive tracer to visualize metabolic activity in the brain?

Explanation: Positron emission tomography (PET) involves injecting a radioactive tracer to visualize metabolic activity in the brain. It provides information about brain function and can be used to study various neurological conditions.

Question 3:

Which brain imaging technique measures electrical activity in the brain using scalp electrodes?

Explanation: Electroencephalography (EEG) measures electrical activity in the brain using scalp electrodes. It provides a measure of neural oscillations and is often used to study brain dynamics during various cognitive tasks.

Question 4:

Which brain stimulation technique involves delivering magnetic pulses to the brain to modulate neural activity?

Explanation: Transcranial magnetic stimulation (TMS) involves delivering magnetic pulses to the brain to modulate neural activity. It is a non-invasive brain stimulation technique used in cognitive neuroscience research and clinical applications.

Question 5:

Which brain imaging technique provides high-resolution structural images of the brain?

Explanation: Magnetic resonance imaging (MRI) provides high-resolution structural images of the brain. It is widely used to study brain anatomy and detect abnormalities in neurological disorders.
