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.
