the things people do...i just googled "straighteners"......Ye gods, they fry your hair into submission !...great way to subdue your sixth sense if ever there was.
If they were going to study what part of hair gives the sixth sense it would be a good way to work it out. Curly hair is rougher along the shaft and therefore along the same length it has more surface area then straight hair. The same reason why you don't iron towels or sheets.
Lack of high frequency sound to stimulate the ear. ... Loud or prolonged noise flattens the fine, hair-like sensor cells (called "cilia") in the inner ear, which ... Sound Therapy was developed by Dr Alfred Tomatis (1920 - 2001), http://www.soundtherapy.com.au/v3/audit ... heory.html
The Centrifugal Pathways are where things start to get interesting. We all struggled with the afferent or input pathways and learned how things got to the brain, but it was that efferent or feed back system that always seemed to be so elusive and not very well understood. The efferent nerves run close to, but not within, the same tracts, as do the afferent nerves. The Superior Olivary Complex is the region of the brainstem where efferent neurons arise and have their point of origin, but are not within the afferent nuclei. It is this system that is responsible for the auditory reflex activities of the stapedius and the tensor tympanic muscles. Traditionally we have been taught that the contraction of these muscles causes the ossicles to become less efficient sound transmitters to the labyrinth, thus protecting the delicate hair cell structure. (Figure 3)
Unorthodox theories view this reflexive activity to be a tuning system that is continually monitoring the tension being applied to the tympanic membrane and providing protection to the hair cells from superatheshold stimuli.
The auditory efferent system is also feeding information back to the contractile outer hair cells pulling the tectorial membrane into the afferent inner hair causing a mechanical fine tuning effect as in attention and sound localization. (Figure 4)
What this means is Dr. Tomatis uses the fine hair like strutures in our ear to stimulate by high frequency (like ear cardio workout) in order to repair damage.
Damage to the hair within the middle ear has very wide reaching affects.
This also affects our ability to hear language, communicate and orient ourselves in space and time.
