The brain is the control centre of your body. To understand where the brain processes the sight of a friendly face across the room or the sound of laughter, read from the heading “The Brain” on page 386 to the questions at the bottom of page 395 in your textbook. This will seem like a significant reading assignment, but concentrate your efforts on the following:

  • the regions of the brain and their functions (The labelled diagram, “Figure 11.24,” on page 387 will further your understanding.)
  • the lobes of the brain and the information they process
  • technologies associated with understanding brain function, injuries, and diseases
Make summary notes or a graphical organizer for future study. Save your work in your course folder.

occipital lobe: one of the four lobes of the cerebrum that receives and analyzes visual information that is sent to association centres for recognition of what is being seen

SC 1. After reading pages 386 to 395 in your textbook and watching “The Central Nervous System and Brain: Orchestrating Life,” you will know that the occipital lobe processes sight and the temporal lobe processes sound. There are, however, four major lobes of the brain.

 

This diagram of the brain provides information about the functions of all four lobes. Consider this information as you identify and label the name for each lobe. After you have labelled the diagram, save it in your course folder for reference.

Self-Check Answers

 

SC 1. You should have labelled your diagram as follows.

  1. frontal lobe
  2. parietal lobe
  3. occipital lobe
  4. temporal lobe

 

SC 2. Check your understanding by answering questions 1, 4, 5, and 6 on page 395 of your textbook. The answers will help you build an understanding of key concepts.

 

You may choose to answer the easier questions mentally, and only record the answers to the questions that you find challenging. Or, you may decide to record your answers to all of the questions. The choices you make will depend upon the recommendation of your teacher, your learning style, your abilities in this subject, and your goals for the course. Verify your answers with your teacher.
