Elementary, my dear.

Supposedly Watson the IBM super computer can analyze your writing to come up with a description of your personality. In response to this post it responded thusly.

You are guarded and somewhat indirect.
You are self-conscious: you are sensitive about what others might be thinking about you. You are independent: you have a strong desire to have time to yourself. And you are intermittent: you have a hard time sticking with difficult tasks for a long period of time.
Your choices are driven by a desire for efficiency.
You consider both helping others and achieving success to guide a large part of what you do. You think it is important to take care of the people around you. And you seek out opportunities to improve yourself and demonstrate that you are a capable person.

At least as good as my horoscope

Left sided birthing

The pain on my right side has been becoming somewhat more manageable. I haven't used as much advil or tylenol. I thought when I started playing with the left sublingual musculature/tongue I thought I would rapidly gain control of it however the process is much larger. It feels like I  am almost 'birthing' a new use of the left side of my head, face, neck sublingual musculature and tongue. It was not what I expected. I have not seen any particular value in what I am doing. It has been quite painful at times. I don't think the process is nearly over (where there would be a somewhat more equitable arrangement in the left and right side dominant control). What is becoming more clear to me that I had previously a false understanding of my right side dominance left side subordinance. There does not seem to be any new dichotomy in my personality. For an analogy it feels more like I had a hand that I never used and it's connections to the arm, shoulder and rest of the body are quite painful and sore to the new adaptation of use. I know I used the left tongue/ jaw/ etc previously but in subordinate pattern to the right. Using the left as the initiator of the movement is something I am finding to be very different.

Painfully superfluous

From the link below it is suggested that dolphins can stay awake just using half their brain. In the work with my 'left tongue'  I do not seem to have any of this ability and I am not sure I would want it. The need to constantly swim and monitor other group members and outside threats may have led to the development of this possibly unique talent.

Playing with the left tongue lately has led to a great deal of pain in my heads and jaws as I do not have the ability to seemingly coordinate all the musculature while in the left side dominant mode.
Much of this pain lately has been in the right side where it feels like I am unable for it to take a more passive subordinate role. The pain interferes with my ability to accurately feel what I am doing and seems to enhance the opposite of what I am trying to do.

I may be on a very superfluous endeavor with no real benefit unlike the dolphins. In some ways though it has taken on a life of it's own and I am not sure I could stop playing with it at this hopefully transition point.

Half awake

Like dolphins, bats may continuously echolocate for extended periods [11]; however most seek shelter and sleep during the day. In contrast, dolphins do not appear to sleep like terrestrial mammals. Instead, unihemispheric sleep has been observed, where slow waves are seen from the cerebral cortex and thalamus on one side of the brain while the opposite side of the brain shows awake physiology [12]. One hemisphere maintains sensory awareness and motor control while the other sleeps [13], [14], [15]. Paradoxical sleep associated with hypotonia and hyporeflexia has not been observed in odontocete cetaceans [16] and would likely result in drowning. Evolutionary pressures selecting for unihemispheric slow wave sleep and the absence of paradoxical sleep, are hypothesized to include: respiratory behavioral demands[13], thermoregulation [17], and continuous vigilance [18]. Dolphins live in cooperative groups and must continuously monitor the location of group members to maintain group cohesion. Even during unihemispheric sleep, where often one eye is closed, the open eye is preferentially gazing in the direction of group members which suggest monitoring group members has a survival advantage [19]. Although predator detection and avoidance will influence vigilant behavior, direct field evidence is difficult to obtain. There is, however, evidence that bottlenose dolphin distribution is modulated by both prey abundance and predation risks, suggesting dolphins monitor their environment for predators [20].

Facial recap

I have been focusing more and more on trying to connect with my left eye to others left eye. Many times while trying to see the persona in the left half of others I notice on my periphery more activity on the right half of face on others. It is almost a flash but the left side does not seem to express as much of these as the right. There are many people that do use the left side in an animate way but it seems still less active than their right for the most part.

It still takes some effort and imagination to see the persona exhibited in the left side. When I glance at the right the persona is there. The left takes some time and I am not always successful. I see the elements of the face on the left but not the person.

Right jaw pain

There have been times when I have experienced a fair amount of pain with playing with the left tongue and the last few days have been tough. However the pain seems to becoming more on the right side jaw by the TMJ joint down through the angle of the jaw and along the lower border. After the pain becomes pretty intense it is hard to feel exactly where it originates. I have taken advil and tylenol more than once and have been unable to sleep at times.

I think the way I used my jaw musculature favored the right tongue jaw in a slightly lengthened position as compared to the left to allow for greater range of action with speech and communication. As my left tongue/jaw musculature seems to grabbing more space my right side is trying to accommodate the new position somewhat unsuccessfully at this time. The left side movements though powerful are spastic and not well controlled. There are times when the pain disappears and comes back when I start playing with the left side control and movements.

So obviously a person with at least a shred of sense would stop trying what I am doing. I don't see any particular benefit in trying to develop the left tongue but it does suggest to me that the right left division in terms of handedness is false. I am right handed based on the way I perceived others and habits of use but could be left handed. (Left tongue/head/spine dominance leading to left shoulder arm hand control and dominance.)

Random Elements

When I switch to left side control of my head it is more like I am discovering the coordination of the different elements than directing them. I can ask for a certain movement such as the turning of my head but there is no way I could have thought of all the separate pieces. However once performing the movement and feeling the different elements of control initiated on the left I can remember them for the next time and try to include them in the movement. The movement feels to be more complete as I discover the different structures that can contribute.

In looking at a person's image in profile that I only see the left side of the head I do see a persona unlike when I view the left side from a full frontal position. What I think I am doing normally in the left profile instance is my right eye dominates and almost makes an assumption what the other person right eye/face/persona is on the clues suggested by the left side image. The dominance of my right eye takes over in reading the left side of the profile. If I put my attention in my left eye I have the same incomplete sense of the persona as I do when see the frontal image.  I have to pay attention and scan a few seconds longer before I am able to see a persona suggested.  Most of the time the persona is more complete when my right eye is directing the scan than my left.

If I close my right eye and look at a someone in the frontal image I don't have any trouble in ascertaining the persona with the natural inclination of seeing the right eye /face even though I am using only my left eye.  However there feels to be a suggestion in myself that my left eye does not come up with the persona but is communicated in my head and my right(left hemisphere) comes up with the image of the persona.

Of course there is a strong possibility that I am completely out to lunch.

The unfortunateness of being a motor moron

Still dealing with the question of why I couldn't tell the difference between most of the left side of my head and the right side.  I can sense in terms of pain and touch quite easily but that is different than movement proprioception. In practising physical therapy there is sometimes the unkind phrase that the patient is a 'motor moron' (applied usually to the non- neurologically involved patient).  It could be a very smart patient or one not quite as bright but when you would ask for a specific movement you would get something completely different than what was asked. Many times it was the phrasing of the language but plenty often the person was incapable of processing what was said in their body. In the training based on the work of Moshe Feldenkrais a generalization could be made, that the person could not differentiate the separate parts and structures in his/her body image.

In most simple terms I am saying I could not tell the difference in movement of the left side and right side of most of my head. The statement at first glance seems somewhat 'moronic' besides it's obvious reflection on myself.

PS Thinking more about this if I was numbed on the right side I believe I would still be able to tell if my mouth was opening on my left. So the above argument needs to be refined to feeling where the movement was initiated. That I could not feel the initiation of the movement on my left side of my head. It feels like I am developing a separate movement image.
