"A Woman Perpetually Falling"

In "A Woman Perpetually Falling" it talked about Bach-y-Rita and his discoveries regarding the brain and showed us one particular case he treated. Cheryl Schlitz has struggled with a faulty vestibular apparatus for five years and can't figure out how to resolve it. Not until she meets with Bach-y-Rita and wears a hat that sends her brain signals from an artificial vestibular apparatus. This is considered a neuroplastic miracle because the tingling sensations on her tongue are somehow finding their way to the brain area that deals with balance. This device could help not only people damaged by gentamicin but also the elderly. With much more usage, Cheryl is able to stay upright and help recover her vestibular function. This is just one example of Bach-y-Rita's discoveries regarding the human brain but he has struggled to come this far with his inventions. People have always viewed the brain as made up of different parts that each perform a specific function and one area can never do the work of another. But, Paul Bach-y-Rita rejected all these ideas and believes in "sensory substitution". He states that all our sense receptors translate into different electrical patterns sent to our nerves and these patterns are the universal language within our brain. Any part of the cortex is able to process whatever electrical signal is sent, so it meant our brain was not so specialized after all. 
1. "An unspoken and yet profound aspect of our well-being is based on having a normally functioning sense of balance" 
It is surprising how much we take granted of our sense of balance. Such important part of our body can have such a huge impact of our lives but rarely do we acknowledge it. It is just another part of our body that we don't realize its' role until it is gone or has a defect. 
2. "She has almost no natural sensors. For the past twenty minutes we provided her with an artificial sensor. But the real miracle is what is happening now that we have removed the device, and she doesn't have either an artificial or a natural vestibular apparatus. We are awakening some kind of force inside her." It is amazing how providing her with an artificial vestibular apparatus has an instant impact on her as expected, but the aftermath is even more shocking. The brain is able to be stimulated and continue with a lasting effect. For her, this is so effective for her to try living like a normal person even though she has no natural or artificial vestibular apparatus. 
3. "Our senses have an unexpectedly plastic nature, he discovered, and if one is damaged, another can sometimes take over for it, a process he calls "sensory substitution" 
The human body is so versatile and can change so quickly to adapt to a new situation that we can't see physically. There are so many senses in our body yet they are able to adapt to a situation and react in a way that is so beneficial.
