How Can Light Cranial Touch Have Therapeutic Efficacy?

This question has always been somewhat of a mystery to me, and have never heard a satisfying answer in the Energetic Kinesiology and Craniosacral Therapy communities. My experience with LENS points to a relatively straightforward explanation:

From LENS, we know that very small (25 microvolts) analog signals fed back to the brain near the operant frequency can have a significant influence on cognition.
From electrical theory, we know that the rate of change of an analog signal is determined by the capacitance of its environment (this is the tech behind the smartphone touchscreen).
When the cranium is touched the local capacitance at that point is increased, decreasing the local frequency (This may be similar to using a negative offset in LENS).
We observe with LENS that feeding back an offset of the sensed frequency at a site changes (perhaps desynchronizes) cognitive function, enabling cognitive repatterning.
I speculate that consistent point-specific touch as described for the Neurovascular points, and in Craniosacral Therapy, by altering localized capacitance, influences cognition foundationally in the same as LENS, but less specific and with a negative offset (which from LENS we know has lessened efficacy1).

1: This lessened efficacy may point to the way that time is utilized by cognition. If a lower frequency offset “drags” on a cognitive process, the drag may simply “lockout” that process from the time-based sequence that process is a part of. A higher frequency offset may push that process ahead in the queue (event cascade) – forcing the downstream cognitive components into an adaptive dynamic. This model may have relevance when exploring phase-shifting vs. frequency shifting feedback offsets.
