DMN activity seems to be associated with primacy of focus on haptic, oscillatory, thermal, and other somatic data types.
CEN activity seems to be associated with primacy of focus on optical and acoustic data types.
I could be mistaken, and IIRC the SN is associated somewhat with somatic data types.
Need to go back and check documentation later.

Progress.
So, it appears that we do (a lot) of our conscious spatial modelling of kinesthesia by abstracting into the optical mode. That is to say, when we mentally prepare to move the body, we (often) visualise the movement, instead of feeling it. Of course we do both, and it is more accurate to do the latter. But the stronger the imagined somatic data signal, the more live SNS somatic signals are displaced from conscious memory, and the greater the risk that SNS-PNS feedback loops currently in-flight would get distorted by the imaginary signal.
For example, say I actually hold a ball. I can imagine visually dropping the ball, or I can imagine haptically dropping the ball. If I imagine too strongly the haptic signal, it appears to my conscious memory that I had felt the ball dropping and my subconscious might step in to modify the MNS signal and mess up my current effort in holding the ball in place. Of course, with more practice, a kinesthete will be able to imagine stronger haptic signals without corrupting their SNS-PNS feedback loops. That is just part of what all manual/physical exercise studies do.
I suppose in college, I didn't think of this distinction much. I mostly thought about activating the DMN as a matter of zeroing my optical and acoustic imagination. I guess that is because most verbal reasoning happens in those sense modalities. But actually a total zeroing is excessive - I should have allowed non-verbal acoustic and optical imagery to remain in the imagined signal. That would have been enough to disengage CEN activities from conscious memory.
Back to thinking about this.
Aside, I must say calcium's hourly effect on neurochemistry is probably the most important thing I picked up over the past 1.5 years. The slower release of chalk in tablet form seems to optimally emulate whole food release rates. The only other thing now is that my stomach is going to get used to producing more acid than it did. So I will have to monitor that
