Advancements in Brain Imaging: Understanding Brain Function and Potential Treatments

The video discusses the use of positron emission tomography (PET) at London's Hammersmith Hospital to track brain activity by monitoring blood flow. It highlights how the left hemisphere of the brain focuses on words, while the right hemisphere processes intonation and vocal characteristics. This technology aids in identifying brain damage and compensatory activity in cases of head injury. The research could lead to new treatments and targeted therapies for conditions like dyslexia.

What is the primary use of positron emission tomography (PET) as mentioned in the video?

• To monitor lung function

• To analyze muscle activity

• To measure heart rate

• To track blood movement in the brain

Which part of the brain is responsible for focusing on words according to the research?

• Frontal lobe

• Left hemisphere

• Occipital lobe

• Right hemisphere

What does the right hemisphere of the brain primarily process?

• Intonation and vocal characteristics
