Ticklishness is defined as a sensation separate from itch or pressure, and I am wondering how the body makes the distinction among the different types of touch. If you could answer some of my questions or direct me in my research, it would be greatly appreciated. I'm under the impression that we still don't know if we have some sort of a soul or if our brains are purely chemical. Thanks a lot for any information you can give me. I am interested in Alzheimer's disease and know that it can be positively identified after death by performing an autopsy on the patient's brain.
Doctors diagnose Alzheimer disease by analyzing a patient's everyday behavior.
