3.4.1 Brain Imaging Techniques

• Brain imaging techniques are methods used to visualize the structure and function of the brain.
• Why are brain imaging techniques important in biological psychology?

  They study brain structure and function non-invasively
• Match the brain imaging technique with its description:

  MRI ↔️ Provides detailed images of brain structure

  fMRI ↔️ Measures changes in blood flow

  PET ↔️ Measures metabolic activity
• What do brain imaging techniques enable researchers to study?

  The brain in vivo
• Functional brain imaging techniques measure brain activity during specific tasks.
• Which brain imaging technique provides detailed images of brain structure?

  MRI
• What does fMRI measure to map brain function?

  Changes in blood flow
• PET scans measure metabolic activity in the brain.
• Brain imaging techniques are crucial in biological psychology as they allow researchers to study the brain's structure and function non-invasively.
• Order the steps in a typical fMRI study:

  1️⃣ Participant lies in the scanner

  2️⃣ Brain activity is measured during a task

  3️⃣ Changes in blood flow are detected

  4️⃣ Data is analyzed to map brain function
• How do brain imaging techniques advance knowledge of psychological processes?

  By mapping brain activity
• What is one benefit of using brain imaging techniques to diagnose neurological conditions?

  Improves patient outcomes
• Why are brain imaging techniques crucial in biological psychology?

  Study brain structure and function
• Understanding brain function allows researchers to map brain activity to specific tasks
• Brain imaging techniques can diagnose conditions such as tumors.
• How do brain imaging techniques enhance treatment efficacy for neurological conditions?

  Develop targeted treatments
• Arrange the following brain imaging techniques based on their primary focus:

• Match the brain imaging technique with its description:

  MRI ↔️ Provides detailed images of brain structure

  fMRI ↔️ Measures changes in blood flow

  PET ↔️ Measures metabolic activity
• Steps in the process of MRI structural brain imaging

  1️⃣ Magnet Alignment

  2️⃣ Radiofrequency Pulse

  3️⃣ Signal Detection

  4️⃣ Image Reconstruction
• In fMRI, changes in blood flow indicate neuronal activity.
• PET scans involve injecting a radioactive tracer into the bloodstream.
• fMRI measures blood flow changes, while PET measures metabolic activity.
• Match the brain imaging technique with its primary purpose:

  MRI ↔️ Visualizes brain anatomy

  fMRI ↔️ Maps brain activity

  PET ↔️ Measures metabolic processes
• MRI has excellent spatial resolution but is time-consuming and expensive.
