The brain

• What is the brain's primary role in the nervous system?

  Control centre of the nervous system
• How does the brain process information?

  It processes information from the senses
• What types of behaviors is the brain responsible for?

  Complex behaviors like memory and emotions
• What are the main structures of the brain and their functions?

  • Cerebral cortex: Consciousness, intelligence, memory, language
  • Cerebellum: Balance, coordination, movement
  • Medulla oblongata: Unconscious activities (heartbeat, breathing)
  • Hypothalamus: Body temperature regulation, controls pituitary gland
  • Pituitary gland: Hormone production and release
  • Spinal cord: Connects brain to body, transmits nerve signals
• What is the function of the cerebral cortex?

  Responsible for consciousness and voluntary actions
• Where is the cerebellum located?

  At the back of the brain
• What does the medulla oblongata control?

  Unconscious activities like heartbeat and breathing
• What is the role of the hypothalamus?

  Regulates body temperature and hormone release
• What does the pituitary gland produce?

  Hormones that regulate body functions
• What is the function of the spinal cord?

  Connects the brain to the rest of the body
• Why is studying the brain important?

  • Helps understand brain function
  • Aids in developing treatments for brain disorders
• How do scientists study brain damage?

  By linking damaged areas to lost functions
• What is the purpose of electrical stimulation in brain studies?

  To observe effects on brain functions
• What does an MRI scan produce?

  Detailed images of the brain's structure
• What can MRI scans detect?

  Tumours, strokes, or brain activity
• What are the difficulties in treating brain disorders?

  • Complexity and delicacy of the brain
  • Risky surgery with potential unintended problems
  • Blood-brain barrier limits medicine access
