My Experience with an EEG Direct Brain Interface Project Brain-Computer Interfaces for the Operation of Commercial Assistive Technology: Sabrina M. Miller Final Project Presented for: Understanding the Brain: The Neurobiology of Everyday Life Coursera MOOC Presented in Conjunction with the University of Chicago and Dr. Peggy Mason 6/30/2014 My Experience with an EEG Direct Brain Interface Project Brain-Computer Interfaces for the Operation of Commercial Assistive Technology Imagine…: Imagine… You are sitting in a chair… You are performing NO deliberate movement. No speaking, moving… nothing. You have a fabric cap that contains electrodes on your head – the only thing connecting it to your scalp are small dots of gel in various places around your scalp. The wires connecting your cap to a computer look just like the ones you see when you open your PC. And, by merely viewing a screen like the one featured here, and the power of your mind, you are able to type. Who does it help? : Who does it help? Although it can help those with a number of physical impairments, such as Muscular dystrophy, spinal cord injury and brainstem stroke, I will focus on ALS as it was the subject named in the study. Amyotrophic Lateral Sclerosis (ALS) or “Lou Gehrig’s Disease” Amyotrophic comes from the Greek language. "A" = no or negative. "Myo“ = muscle “Trophic" = nourishment COMBINED: "No muscle nourishment." Lateral identifies the areas in a person's spinal cord where portions of the nerve cells that signal and control the muscles are located. Sclerosis: As this area degenerates it leads to scarring or hardening ("sclerosis") in the region. What Portions of the Nervous System are Affected?: What Portions of the Nervous System are Affected? In ALS both upper and lower motor neurons in the motor cortex of the brain, the brain stem, and the spinal cord die. Ph: ALS Association Website As the motor neurons and axons degenerate, muscles no longer receive signals and they atrophy Survivability depends on the speed of degeneration. Half of all people affected with ALS live at least three or more years after diagnosis. Twenty percent live five years or more Up to ten percent will live more than ten years. For example: Stephen Hawking, who was diagnosed with ALS at the age of 22 is still generating amazing scientific work at the age of 72! How Did It Feel? : How Did It Feel? How Has “Understanding the Brain: The Neurobiology of Everyday Life Helped Me” Understand My Volunteer Work?: How Has “Understanding the Brain: The Neurobiology of Everyday Life Helped Me” Understand My Volunteer Work? While the idea of electrical impulses from the brain to the computer interface had made sense to me at the time of the study, this course has helped me understand What parts of the nervous system are affected in those people who would be utilizing this technology. What parts of the nervous system would NOT be affected in those people who would be utilizing this technology. A greater understanding of how motor, sensory and are separate systems. The fragility of the system of motor neurons (and how few there actually are) PowerPoint Presentation: Published results of the research I participated in: Thompson DE Gruis KL, Huggins JE: A plug-and-play brain-computer interface to operate commercial assistive technology.
