What does a PET scan measure in the brain?

• The electrical activity of neurons

• The magnetic fields produced by neural activity

• The consumption of glucose by brain areas

• The alignment of spinning atoms in brain molecules

Which technique is used to study the brain's electrical activity in real-time?

• MRI

• EEG

• PET

• MEG

How does the use of optogenetics help neuroscientists?

• Optogenetics helps neuroscientists by changing the color of neurons
• Optogenetics allows neuroscientists to control weather patterns in the brain
• Optogenetics is used by neuroscientists to communicate with aliens
• Optogenetics helps neuroscientists by allowing them to selectively inhibit specific neurons using light.

What brain structure is highlighted by MRI scans in patients with schizophrenia?

• The hippocampus

• The amygdala

• The ventricles

• The corpus callosum

Which imaging technique uses a strong magnetic field and radio waves to produce detailed images of brain tissues?

• CT

• PET

• MRI

• MEG

What is one of the limitations of using EEG for brain research?

• Invasive procedure
• Limited spatial resolution
• High cost of equipment
• Unlimited spatial resolution

What insight does brain connectivity research provide for understanding psychological disorders?

• It helps in identifying brain regions involved in sensory perception.

•  It reveals how different brain regions communicate and interact.

•  It detects magnetic fields produced by neurons during specific tasks.

• It measures the glucose consumption of active brain areas.

What is the primary function of the brainstem?

• Regulating emotions

• Controlling heartbeat and breathing

• Processing sensory information

• Coordinating voluntary movement

How does the brainstem's function differ from the brain's higher regions?

• The brainstem regulates sleep patterns, whereas the brain's higher regions manage sensory perception.
• The brainstem controls basic life functions, whereas the brain's higher regions are involved in complex cognitive processes.
• The brainstem coordinates memory functions, while the brain's higher regions oversee hormonal balance.
• The brainstem is responsible for emotions, while the brain's higher regions control physical movements.

What role does the thalamus play in sensory information processing?

• The thalamus is responsible for motor control
• The thalamus plays a role in relaying sensory information

• The thalamus regulates hormone production
• The thalamus stores long-term memories
