Neuro Psychology Quiz 1

What is the main focus of cognitive neuroscientists?

• Studying the behavior of abnormal brains

• Exploring the connection between memory and brain structure

• Investigating the anatomical structures of the brain

• Analyzing the impact of diseases on brain function

Which scanning technique uses a series of x-rays to produce detailed black-and-white cross-sectional images of the brain?

• MRI scanner

• PET scanner

• fMRI scanner

• CT scanner

What is the main advantage of PET scanners over CT scanners?

• They use large magnets to measure brain activity

• They have better temporal resolution

• They show brain activity

• They are cheaper to perform

What did the researcher Tolving find when using a PET scanner to study long-term memory?

• No consistent difference in blood flow among the participants

• No difference in blood flow when recalling different types of memories

• Activity in the frontal and temporal lobes when recalling semantic memories

• Activity in the peripheral and occipital lobes when recalling episodic memories

What is the main cause of strokes?

• Radiation risk from CT scans

• Physical damage to the brain

• Clot blocking a blood supply to the brain

• Neurological damage to the neurons

Which area of the brain controls decision-making?

• Limbic system

• Temporal lobe

• Frontal lobe

• Motor cortex

What is the main drawback of fMRI scanners?

• They use radiation which poses a risk to the patient

• They are more expensive than CT scanners

• They have poor temporal resolution

• They don't show brain activity

What is the historical way of investigating brain function before the use of scanning techniques?

• Using radioactive tracers to detect brain activity

• Studying the behavior of abnormal brains

• Matching an ability to a particular location in the brain

• Investigating the anatomical structures of the brain
