Biopsychology: Studying the Brain - EEG & ERP Quiz

What does an electroencephalogram (EEG) measure?

• Electrical activity in the brain

• Blood flow in the brain

• Chemical activity in the brain

• Magnetic fields in the brain

Which of the following is NOT a type of EEG pattern?

• Alpha waves

• Delta waves

• Gamma waves

• Theta waves

What is the main difference between EEG and ERP?

• EEG is used for sleep studies, ERP is not

• ERP involves presenting a stimulus, EEG does not

• ERP measures blood flow, EEG measures electrical activity

• EEG uses electrodes, ERP does not

What is the term for the time between the presentation of a stimulus and the response in ERP studies?

• Frequency

• Latency

• Alpha waves

What is the purpose of 'averaging' in ERP studies?

• To measure blood flow

• To reduce extraneous neural activity

• To detect magnetic fields

• To increase the amplitude of the response

Which EEG pattern is associated with REM sleep?

• Fast desynchronized activity

• Slow synchronized activity

What are sensory ERPs?

• Responses occurring after 100 milliseconds

• Responses occurring within 100 milliseconds

• Responses related to cognitive processing

• Responses related to motor activity
