Brain Scan

Front

A patient is experiencing unusual bouts of memory loss and mood swings. Doctors suspect that there might be abnormal activity in the brain regions associated with these functions. To investigate, they inject the patient with a radioactive tracer and observe the brain activity while the patient performs memory and mood-related tasks.

Pet Scan

Front

A patient arrives at the emergency room after a car accident, complaining of severe headaches and dizziness. The doctors need to quickly assess if there is any structural damage or bleeding in the brain. They decide to use an imaging technique that provides detailed cross-sectional images of the brain.

CT Scan

Front

Researchers are studying the brain regions involved in decision-making. They ask participants to perform a series of decision-making tasks while lying inside a scanner that measures changes in blood flow to different parts of the brain. What type of scan is being used? Options: PET Scan, Lesions, fMRI, MRI

Back

fMRI

Front

A neurologist is investigating the cause of a patient's frequent seizures. They attach electrodes to the patient's scalp to measure and record the electrical activity of the brain over a period of time, especially during sleep.

Back

EEG

Front

In a controlled laboratory setting, researchers are studying the effects of specific brain regions on behavior in animals. They surgically remove or destroy targeted areas of the brain to observe changes in the animals' behavior and understand the functions of those regions.

Back

Lesions

Front

A patient has been experiencing persistent, unexplained headaches. Doctors want to get a detailed image of the brain's soft tissues to look for tumors or abnormalities. They decide to use a non-invasive imaging technique that uses strong magnetic fields and radio waves.

Back

MRI

Front

A sleep researcher is studying the different stages of sleep in participants. They attach electrodes to the participants' scalps to monitor and record the electrical activity of the brain throughout the night.

Back

EEG

Front

Psychologists are investigating the neural mechanisms of empathy. They have participants watch videos depicting various emotional scenarios while in a scanner that tracks changes in blood flow to different brain regions associated with emotional processing. What type of scanner is being used?

Back

FMRI

Front

In a study on animal behavior, scientists are investigating the role of a specific brain region in fear responses. They selectively destroy this brain region in a group of rats and then observe the changes in their behavior when exposed to stimuli that previously induced fear. What imaging technique is being used? Options: EEG, CT, PET, FMRI

Back

PET

Front

An elderly patient has been showing signs of cognitive decline. To check for signs of a stroke or other structural abnormalities in the brain, doctors decide to use an imaging technique that can quickly provide a detailed view of the brain's structure.
