Transcript

  • 1. **The Brain** in Brain Computer Interface An Do, MD Department of Neurology University of California, Irvine
  • 2. The Brain • Source of thought, behaviors, and perceptions • Composed of billions of neurons in interconnected networks
  • 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. Movement Sensation Coordination
  • 5. Left vs Right Brain
  • 6. The Nervous System
  • 7. Brain Function Integration • Integration of all brain functions and neurological processes is similar to how multi- core computer processors work.
  • 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. Stroke
  • 10. Seizures
  • 11. Parkinson’s disease
  • 12. Dementia
  • 13. Brain Cancer
  • 14. Spinal Cord Injury
  • 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. 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
