Which technique is used to detect blood oxygenation and flow in the brain to produce a 3D map in real time?

• Electroencephalogram (EEG)

• Event-Related Potentials (ERPs)

• Functional magnetic resonance imaging (fMRI)

• Computed Tomography (CT)

What is a major advantage of fMRI as a therapy?

• It is inexpensive

• It has a high temporal resolution

• It does not rely on the use of radiation

• It directly measures neuronal activity

Which technique uses a skull cap with a series of electrodes to measure brainwave patterns?

• Functional magnetic resonance imaging (fMRI)

• Event-Related Potentials (ERPs)

• Electroencephalogram (EEG)

• Computed Tomography (CT)

What is a primary use of EEG in medical studies?

• To measure blood flow in the brain

• To diagnose epilepsy

• To create a 3D map of the brain

• To measure oxygen levels in the brain

What is a limitation of EEG mentioned in the text?

• It is very expensive

• It has poor spatial resolution

• It uses radiation

• It cannot measure brainwave patterns

What are Event-Related Potentials (ERPs) generated from?

• fMRI data

• EEG data

• CT scan data

• PET scan data

What is a disadvantage of ERPs?

• They are less specific than EEG

• They are very expensive

• It is hard to reliably remove background data

• They use radiation

What is the main function of the suprachiasmatic nucleus (SCN)?

• To regulate blood pressure

• To control digestion

• To act as a master circadian pacemaker

• To manage muscle movements

What is the primary input that sets the body clock in the process called photoentrainment?

• Sound

• Light

• Temperature

• Smell

What is one of the ethical issues associated with post-mortem analysis in psychological research?

• High cost of the procedure

• Difficulty in obtaining accurate results

• Fully informed consent of patients donating their brain to research

• Lack of trained professionals
