the brain

• What is the primary role of the brain?


  The brain is the control center of the body.
• What are the main functions of the brain?


  Managing complex behaviors, processing sensory information, and coordinating responses.
• What is the composition of the brain?

  The brain consists of billions of interconnected neurones and various regions.
• What are the key structures of the brain?

  • Cerebral Cortex
  • Cerebellum
  • Medulla Oblongata
• Where is the cerebral cortex located?


  The cerebral cortex is the outer layer of the brain.
• What higher brain functions does the cerebral cortex involve?


  Thought, reasoning, memory, and voluntary movement.
• What sensory information does the cerebral cortex process?


  Touch, taste, vision, and hearing.
• How is the cerebral cortex divided?


  It is divided into left and right hemispheres.
• What does each hemisphere of the cerebral cortex control?


  Each hemisphere controls the opposite side of the body.
• Where is the cerebellum located?


  The cerebellum is located at the back of the brain, below the cerebral cortex.
• What is the function of the cerebellum?


  It coordinates voluntary muscle movements and maintains balance and posture.
• What role does the cerebellum play in motor learning?


  The cerebellum plays a role in timing of movements and motor learning.
• Where is the medulla oblongata located?


  The medulla is located at the base of the brain, just above the spinal cord.
• What involuntary functions does the medulla control?


  Breathing, heart rate, and blood pressure.
• What is the role of the medulla as a pathway?


  It acts as a pathway for signals between the brain and spinal cord.
• What are the challenges in investigating brain function?

  • Complexity of the brain's structure and connections
  • Delicacy of brain tissue leading to potential damage
• What are the methods of investigating brain function?

  1. Brain Damage Studies
  2. Electrical Stimulation
  3. MRI Scanning
• How do brain damage studies help in understanding brain function?


  They help identify functions associated with damaged areas.
• What is the purpose of electrical stimulation in brain research?


  It allows researchers to see the effects on behavior and sensation.
• What does MRI scanning provide in brain research?


  MRI provides detailed images of brain structures.
• What ethical considerations are involved in brain research?


  • Weighing benefits against risks
  • Importance of informed consent
• Why is informed consent crucial in brain surgeries?


  It ensures patients understand the risks and benefits of the procedure.
