  1. Watch the following clip • How is brain surgery different today different from brain surgery in the 1940’s? • Why did the patient need to be awake?

  2. Learning Objectives • Describe the structure of the brain. • Recall how scientists learn about the brain. • Discuss some of the ethical issues involved in the study of the brain.

  3. The Brain On the right hand page you are going to make notes and complete activities throughout the lesson For the end of the lesson Left hand side, right hand side

  4. Paired interview Read through the information on your card. Make summary notes in your exercise books (you can talk to your partner about this!) Don’t forget to write title and the date!!

  5. Paired interview In pairs interview the pair opposite about the information on their card. Your pair will then be interviewed. Make notes about the other pairs information You can only do that AFTER the interview is finished

  6. The Brain • Simple Animals – have a large mass of neurons at the head end • Complex animals – have a brain made of billions of neurons • It has many areas, each carry out a function • Allows you to learn from experience

  7. Watch the clip about the structures of the brain The Brain

  8. Brain Role Play Survival

  9. Cerebellum • Latin for “Little Brain” • Primitive part of the brain • Survival • Responsible for Fight or Flight and Reproduction

  10. Brain Role Play Emotional (1)

  11. Temporal Lobe 1 • Links the nervous system with the endocrine system • Release oxytocin from pituitary gland (Chemical of love) • Responsible for protection and nurturing instincts

  12. Brain Role Play Emotional (2)

  13. Temporal Lobe 2 • Storage of traumatic memories • Fear conditioning (e.g. phobias) • If the amygdala is damaged then organisms can become fearless • Is this a good thing?

  14. Brain Role Play Cerebral Cortex

  15. Cerebral Cortex • Consciousness • Intelligence • Language • Memory • Very Large in Humans

  16. Brain labelling • Use the information around the room to label your diagram of the brain. • Add detailed notes from the slide to your diagram.

  17. Finding out about the brain? How do we know about the structure and function of the brain?

  18. Finding out... MRI and fMRI scans are one way we find out about the structure of the brain. The patient is awake The skull is not cut open Normal life can continue after the scan

  19. Injured Brains • Awake Brain Surgery • People who have had accidents e.g. Phineas Gage • Stroke Victims • Are there any problems studying brains in this way?

  20. Finding out... write down some ethical issues associated with finding out about the brain in this way

  21. Past Question Stuart is a doctor studying the Cerebral Cortex of the brain. One of Stuart’s patients has damage to her cerebral cortex. Suggest two processes that are most damaged by this. [2 marks] Suggest how Stuart could find out exactly which parts of the brain are damaged [2 marks]

  22. Answers • Memory, speech, • Look at images on an MRI Scan, apply an electrical charge to different parts of the brain.

  23. The Brain Your Notes Left hand side, right hand side Jokes show how much you get it – draw your own cartoon with a joke about the brain to make someone else in the class laugh…
