All 15 questions on Coordination and the brain, as a list
- June 2024, Paper 2, Q1(b)(i) (2 marks): Describe the advantages of using PET and fMRI rather than MRI scans to investigate a possible tumour in the brain. (2)
- June 2024, Paper 2, Q1(b)(ii) (1 mark): The images show brain scans produced from two imaging techniques other than PET. Image 1 Image 2 (Source: ZEPHYR/SCIENCE PHOTO LIBRARY) (Source: ALFRED PASIEKA/
- June 2024, Paper 2, Q1(c) (2 marks): The diagram shows a human brain. P Q Brain tumours can change brain function. Describe the possible effects of brain tumours in parts P and Q. (2) P Q
- June 2022, Paper 2, Q2(a) (1 mark): A student produced a table linking three descriptions of brain function to a labelled diagram of the brain. Label Description of function of labelled region in
- June 2022, Paper 2, Q2(b)(i) (3 marks): Describe why a region of the brain might appear lighter in an image obtained by a functional magnetic resonance image (fMRI) scan. (3)
- June 2022, Paper 2, Q2(b)(ii) (3 marks): One scan combines positron emission tomography (PET) and computed tomography (CT). This scan can be used to show whether a person has cancer. Describe why a com
