**The Brain** in Brain Computer Interface

  1. 1. **The Brain** in Brain Computer Interface An Do, MD Department of Neurology University of California, Irvine
  2. 2. The Brain • Source of thought, behaviors, and perceptions • Composed of billions of neurons in interconnected networks
  3. 3. Brain Anatomy • 3 Major Parts – Cerebrum • Frontal lobe • Temporal lobe • Parietal lobe • Occipital lobe – Brainstem – Cerebellum Frontal Lobe Parietal Lobe Temporal Lobe Occipital Lobe Cerebellum Brainstem
  4. 4. Movement Sensation Coordination
  5. 5. Left vs Right Brain
  6. 6. The Nervous System
  7. 7. Brain Function Integration • Integration of all brain functions and neurological processes is similar to how multi- core computer processors work.
  8. 8. Diseases of the Nervous System • In such a complicated system, if any part is damaged, many problems can occur. • Neurologists, neurosurgeons, and neuroscientists study these problems
  9. 9. Stroke
  10. 10. Seizures
  11. 11. Parkinson’s disease
  12. 12. Dementia
  13. 13. Brain Cancer
  14. 14. Spinal Cord Injury
  15. 15. Neurological Injury • Injury to the nervous system often causes irreversible damage – results in disability, sometimes devastating – occasionally results in very bizarre symptoms • Neurologists, neurosurgeons, and neuroscientists are actively studying brain injury to arrive at new understanding of the brain and new treatments – the Brain Computer Interface is one such example
  16. 16. Why study the brain and nervous system ? • It’s the control center ! • There are many things even scientists still don’t know • Search for better understanding of brain function and brain repair • The answer to these problems will rely not only on the current generation of physicians and scientists alone, but also on future generations to come
