      Lesson details

      Learning outcome

      I can describe the main regions of the brain and their functions.

      Key learning points

      1. The human brain is an organ made of billions of neurones.
      2. The brain acts as the processing centre for the nervous system.
      3. Key regions of the brain (e.g. cerebral cortex, cerebellum, brain stem) and the processes they regulate.

      Keywords

      • Brain - The organ which controls responses to the internal and external environments.

      • Cerebral cortex - The part of the brain responsible for conscious thoughts and responses.

      • Cerebellum - The part of the brain responsible for conscious movement.

      • Brain stem - The part of the brain responsible for unconscious control of the body.

      Common misconception

      Confusion around which functions of the brain operate where, the level of detail required, and how these functions can become impaired through injury or disease are common.

      The role and parts of the brain are covered in detail and separately to avoid confusion. Quick checks and tasks focus on areas of misunderstanding to reinforce the correct message and help identify those who have got it wrong.

      Teacher tip

      Don't go into detail about the lobes of the cerebral cortex: they are not needed at GCSE. Instead, focus on ensuring students can correctly assign the functions to the areas, and spend time checking this, with more checks if necessary.

      Equipment

      None required.
