Dr. Reside's experiment can not be considered effective because his study has only treatment subjects group and lack of control group. That's why his study can be very good but not valid without control group.
In his study, he concluded that 80% children after therapeutic treatment decreased the activity level which can be true but not valid without control group because when he use control group in his study then we will be able to compare the normal or control group and treatment group. Then the study will be valid and effective as well.
I'm rather confused about your question, but I believe you are referring to a blind spot caused by your optic nerve. The optic nerve runs from your retina to your brain, it sends all the visual information that your retina picks up. Because this nerve does not have any cones or rods on it, like your retina does, you cannot see with this part of your eye. By positioning an object correctly and looking at something at the right angle, the object can seem to disappear. Your brain usually just imagines a picture in this blind spot, so as to fill in the gap.
