i had wondered the analogue of microtubule computation in HTMs.
microtubules, as measured, are operating at several space scale magnitudes
smaller and faster than individual neurons. whether or not they influence
macroscopic neural activity, the cylindrical matrices can store and process
additional memory bits "in-between" and "inside-of" neurons. their design
might be adapted somehow.  here's some notes

In January 2014, Hameroff and Penrose announced that the discovery of
quantum vibrations inmicrotubules by Anirban Bandyopadhyay of the National
Institute for Materials Science in Japan in March 2013[20] confirms the
hypothesis of the Orch-OR theory.[10][21]

Moreover, the transmitted ac power and the transient fluorescence decay
(single photon count) are independent of the microtubule length. Even more
remarkable is the fact that the microtubule nanowire is more conducting
than a single protein molecule that constitutes the nanowire. Microtubule's
vibrational peaks condense to a single mode that controls the emergence of
size independent electronic/optical properties, and automated noise
alleviation, which disappear when the atomic water core is released from
the inner cylinder.

A single microtubule, acts just like a single molecule oscillator, the
frequency ranges of three resonance bands are (10^4 ~ 10^10 Hz, gap in
order ~6) Triplet 1 (15–20 kHz, 25–80 kHz, 100–300 kHz), Triplet 2 (10–19
MHz, 20–40 MHz, 100–228 MHz), Triplet 3 (1–5 GHz, 7–10 GHz, 15–30 GHz).

Microtubule is electrical insulator (~300 mega Ohms), however, at
particular ac frequencies, the dc conductivity decreases several orders of
magnitude to a few kilohms.[32] These frequencies are termed as
electromagnetic resonance frequency. Sahu et al exhibited multi-level
memory switching properties storing as much as ~500 bits, reversible
switching like Random Access Memory (RAM) devices. Single molecule
multi-level memory switching is an advanced atomic scale measurement
technique,[33] which exhibits massively parallel computing.[34]
