Introduction to Brain Imaging Techniques Quiz for Psychology Students

🧠 Quick Study Guide

• 🔬 Electroencephalography (EEG): Measures electrical activity in the brain using electrodes placed on the scalp. Excellent temporal resolution but poor spatial resolution.
• 🧲 Magnetoencephalography (MEG): Measures magnetic fields produced by electrical activity in the brain. Better spatial resolution than EEG, but expensive and sensitive to movement.
• ☢️ Computed Tomography (CT): Uses X-rays to create detailed images of the brain's structure. Good spatial resolution, but involves radiation exposure.
• 🌡️ Magnetic Resonance Imaging (MRI): Uses magnetic fields and radio waves to create high-resolution images of the brain's structure. Excellent spatial resolution and no radiation, but expensive and can be uncomfortable for some.
• 🩸 Functional Magnetic Resonance Imaging (fMRI): Detects changes in blood flow to measure brain activity. Good spatial and temporal resolution, but susceptible to artifacts.
• 🎯 Positron Emission Tomography (PET): Uses radioactive tracers to measure metabolic activity in the brain. Can be used to study neurotransmitter function, but involves radiation exposure and has limited spatial resolution.
• 💡 Transcranial Magnetic Stimulation (TMS): Uses magnetic pulses to stimulate or inhibit brain activity. Can be used to study the function of specific brain regions.
