I learned quite a lot from the video. Until I watched this video science of sense , I did not know of a device like the Voice, which enables people with site problems like Pat to see objects through hearing. It is so fascinating just how the gadget operates. I also learnt that individuals who have the condition of facial blindness could differentiate people by the hair. Though I knew of such a condition, I was not aware it is called prosopagnosia, neither did I know about this aspect of recognition through the hair. It is so inspiring how people like Pat living with physical challenges still find a way to live through the challenges. It taught me a life lesson to always appreciate the little things we always tend to ignore, like the ability to recognize people by faces. The questions I have is concerning the primary qualities that are independent of us. What exactly are they? What makes them independent of us?
Dear Chinyere Okpala,
Facial blindness is caused by damage or malfunction of the right fusiform gyrus (Lewis, 2013). It is the part of the brain that coordinates the control of memory and facial recognition (Lewis, 2013). I believe the lack of self-awareness will occur in patients whose sense of memory have been adversely affected.
Delegate your assignment to our experts and they will do the rest.
Dear Bryan Brown White
Eighty percent of visual impairments disorders have a cure (McIntosh, 2015). The 80% represent visual impairments resulting from cataracts and refractive errors. Retinal degeneration disorders cause the remaining 20% of blindness cases, a condition that has no cure presently (McIntosh, 2015). Scientists have identified and are working on four technologies that give some ray of hope regarding the treatment of this condition (Makin, 2019). However, according to this author, we are nowhere near getting the cure for retinal degeneration, which is the only medical way for the blind to regain sight.
