Which of the following statements best describes EEG?

• It has high spatial resolution but low temporal resolution

• It measures blood oxygen levels to track neural activity

• It has high temporal resolution but low spatial resolution

• It tracks water molecule diffusion in the brain

Which EEG frequency band is primarily associated with deep sleep?

• Alpha (8–12 Hz)

• Beta (12–30 Hz)

• Delta (0.5–4 Hz)

• Gamma (30+ Hz)

The Theta frequency band (4–8 Hz) is most commonly associated with:

• Focus and active thinking

• Meditation and drowsiness

• Self-referential thought

• Problem-solving

What does fMRI primarily measure to infer brain activity?

• Direct neuronal firing

• The movement of water molecules in brain tissue

• Changes in blood oxygenation levels

• Electrical signals from individual neurons

One major advantage of fMRI over EEG is:

• Higher temporal resolution

• Higher spatial resolution

• Direct measurement of electrical activity

• Ability to stimulate brain regions

Transcranial Magnetic Stimulation (TMS) is primarily used to:

• Induce or inhibit neuronal activity using magnetic pulses

• Measure electrical signals in the brain

• Track blood flow changes in different brain regions

• Stimulate neurotransmitter release in the hippocampus

Diffusion MRI (dMRI) is particularly useful for:

• Mapping the structure of white matter pathways

• Measuring electrical activity of neurons

• Studying changes in blood oxygenation

• Detecting neurotransmitter release in synapses

Single-cell recording is a technique used to:

• Measure the electrical activity of an individual neuron

• Track blood oxygen levels in a brain region

• Stimulate large-scale brain networks

• Map white matter pathways in the brain

Which large-scale network is most associated with self-referential thought and mind-wandering?

• Executive control network

• Salience network

• Default mode network

• Sensorimotor network

The Executive Control Network is primarily involved in:

• Filtering sensory input and shifting attention

• Self-referential thought and memory recall

• Goal-directed behavior and problem-solving

• Regulating bodily functions like breathing
