Previous Brain Structure Next Treating Brain Damage & Disease
  • Neuroscientists study the brain and its functions.
  • Techniques to map brain areas to functions include studying brain damage, electrical stimulation, and MRI scanning.
  • Studying brain damage, such as from a stroke, can reveal functions like balance if damage leads to loss of balance.
  • Electrical stimulation involves using electrodes to stimulate brain parts and observing effects like distorted vision, indicating the stimulated part's function.
  • MRI (Magnetic Resonance Imaging) is a less invasive technique that uses strong magnetic fields to produce brain images.
  • During MRI scans, patients may perform tasks like speaking or tapping fingers to highlight active brain areas.
  • MRI images show highlighted areas in different colors representing active regions during specific tasks, helping map brain functions to specific tasks.
