Front

What type of electrophysiology measures action potentials?

Back

Single units measure action potentials.

Front

What technique involves injecting a radioactive tracer into the bloodstream to visualize brain activity?

Back

PET (Positron Emission Tomography) involves injecting a radioactive tracer.

Front

Which neurosurgical method does not require cutting into the patient?

Back

Gamma knife surgery does not require cutting into the patient.

Front

Which imaging technique uses radiation?

Back

PET uses radiation.

Front

What does the presence of ataxia suggest damage to?

Back

Front

What does EEG stand for and what does it measure?

Back

EEG stands for Electroencephalography and measures electrical activity in the brain.

Front

What is the main purpose of MRI in clinical neuroimaging?

Back

MRI (Magnetic Resonance Imaging) is used to visualize internal structures of the brain without radiation.

Front

What is the difference between fMRI and PET?

Back

fMRI measures brain activity by detecting changes in blood flow, while PET uses radioactive tracers.

Front

What is deep brain stimulation (DBS)?

Back

DBS is a neurosurgical procedure that involves implanting electrodes in specific brain areas to treat neurological disorders.
