Ways of studying the brain

What is the main assumption of functional magnetic resonance imaging (fMRI)?

• fMRI measures blood flow in the brain

• fMRI measures electrical activity in the brain

• fMRI measures neurotransmitter levels in the brain

• fMRI measures brain structure

What is the temporal resolution of fMRI?

• 1-4 seconds

• 1-10 milliseconds

• 1-2 millimeters

• 1-4 milliseconds

What is the spatial resolution of fMRI?

• 1-4 seconds

• 1-10 milliseconds

• 1-2 millimeters

• 1-4 centimeters

What does an EEG measure?

• Blood flow in the brain

• Electrical activity in the brain

• Neurotransmitter levels in the brain

• Brain structure

What is the main difference between EEG and ERP?

• EEG measures electrical activity, while ERP measures blood flow

• EEG measures brain structure, while ERP measures neurotransmitter levels

• EEG measures brain activity over time, while ERP measures activity related to specific stimuli

• EEG measures deep brain regions, while ERP measures superficial areas

What is the main advantage of post-mortem examination?

• It provides real-time brain activity measurements

• It has high spatial resolution

• It is considered an ethical procedure

• It allows for detailed examination of brain anatomy and deeper regions of the brain

Which brain scanning technique was first used to support the theory of brain localisation?

• fMRI

• EEG

• ERP

• Post-mortem examination

What is the main limitation of EEG?

• It has low spatial resolution

• It is an invasive procedure

• It cannot detect brain activity in deep regions

• It cannot provide information about brain disorders

What type of brain measuring technique produces the following reading?

• MRI

• fMRI

• PET

• ERP

Which technique is most appropriate for investigating brain wave patterns associated with stages of sleep?

• ERP

• PET

• fMRI

• EEG
